    - by Shaik Phakeer
    Hi All, Here I am trying to assign the datasource (using same code given in the sample application) and create a graph, only difference is i am doing it in WPF WindowsFormsHost. due to some reason the datasource is not being assigned properly and i am not able to see the series ("Series 1") being created. wired thing is that it is working in the Windows Forms application but not in the WPF one. am i missing something and can somebody help me?

  • Subsonic Access To App.Config Connection Strings From Referenced DLL in Powershell Script

    - by J Wynia
    I've got a DLL that contains Subsonic-generated and augmented code to access a data model. Actually, it is a merged DLL of that original assembly, Subsonic itself and a few other referenced DLL's into a single assembly, called "PowershellDataAccess.dll. However, it should be noted that I've also tried this referencing each assembly individually in the script as well and that doesn't work either. I am then attempting to use the objects and methods in that assembly. In this case, I'm accessing a class that uses Subsonic to load a bunch of records and creates a Lucene index from those records. The problem I'm running into is that the call into the Subsonic method to retrieve data from the database says it can't find the connection string. I'm pointing the AppDomain at the appropriate config file which does contain that connection string, by name. Here's the script. $ScriptDir = Get-Location [System.IO.Directory]::SetCurrentDirectory($ScriptDir) [Reflection.Assembly]::LoadFrom("PowershellDataAccess.dll") [System.AppDomain]::CurrentDomain.SetData("APP_CONFIG_FILE", "$ScriptDir\App.config") $indexer = New-Object LuceneIndexingEngine.LuceneIndexGenerator $indexer.GeneratePageTemplateIndex("PageTemplateIndex"); I went digging into Subsonic itself and the following line in Subsonic is what's looking for the connection string and throwing the exception: ConfigurationManager.ConnectionStrings[connectionStringName] So, out of curiosity, I created an assembly with a single class that has a single property that just runs that one line to retrieve the connection string name. I created a ps1 that called that assembly and hit that property. That prototype can find the connection string just fine. Anyone have any idea why Subsonic's portion can't seem to see the connection strings?

  • c# linq to xml to list

    - by WtFudgE
    I was wondering if there is a way to get a list of results into a list with linq to xml. If I would have the following xml for example: <?xml version="1.0"?> <Sports xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <SportPages> <SportPage type="test"> <LinkPage> <IDList> <string>1</string> <string>2</string> </IDList> </LinkPage> </SportPage> </SportPages> </Sports> How could I get a list of strings from the IDList? I'm fairly new to linq to xml so I just tried some stuff out, I'm currently at this point: var IDs = from sportpage in xDoc.Descendants("SportPages").Descendants("SportPage") where sportpage.Attribute("type").Value == "Karate" select new { ID = sportpage.Element("LinkPage").Element("IDList").Elements("string") }; But the var is to chaotic to read decently. Isn't there a way I could just get a list of strings from this? Thanks

  • Etiquette for refactoring other people's sourcecode?

    - by Prutswonder
    Our team of software developers consists of a bunch of experienced programmers with a variety of programming styles and preferences. We do not have standards for everything, just the bare necessities to prevent total chaos. Recently, I bumped into some refactoring done by a colleague. My code looked somewhat like this: public Person CreateNewPerson(string firstName, string lastName) { var person = new Person() { FirstName = firstName, LastName = lastName }; return person; } Which was refactored to this: public Person CreateNewPerson (string firstName, string lastName) { Person person = new Person (); person.FirstName = firstName; person.LastName = lastName; return person; } Just because my colleague needed to update some other method in one of the classes I wrote, he also "refactored" the method above. For the record, he's one of those developers that despises syntactic sugar and uses a different bracket placement/identation scheme than the rest of us. My question is: What is the (C#) programmer's etiquette for refactoring other people's sourcecode (both semantic and syntactic)?

  • Android using ksoap calling PHP SOAP webservice fails: 'procedure 'CheckLogin' not found

    - by AmazingDreams
    I'm trying to call a PHP SOAP webservice. I know my webservice functions correctly because I use it in a WPF project succesfully. I'm also building an app in android, using the same webservice. The WSDL file can be found here: http://www.wegotcha.nl/servicehandler/service.wsdl This is my code in the android app: String SOAP_ACTION = "http://www.wegotcha.nl/servicehandler/CheckLogin"; String NAMESPACE = "http://www.wegotcha.nl/servicehandler"; String METHOD_NAME = "CheckLogin"; String URL = "http://www.wegotcha.nl/servicehandler/servicehandler.php"; String resultData = ""; SoapSerializationEnvelope soapEnv = new SoapSerializationEnvelope(SoapEnvelope.VER11); SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); SoapObject UserCredentials = new SoapObject("Types", "UserCredentials6"); UserCredentials.addProperty("mail", params[0]); UserCredentials.addProperty("password", md5(params[1])); request.addSoapObject(UserCredentials); soapEnv.setOutputSoapObject(request); HttpTransportSE http = new HttpTransportSE(URL); http.setXmlVersionTag("<?xml version=\"1.0\" encoding=\"utf-8\"?>"); http.debug = true; try { http.call(SOAP_ACTION, soapEnv); } catch (IOException e) { e.printStackTrace(); } catch (XmlPullParserException e) { e.printStackTrace(); } SoapObject results = null; results = (SoapObject)soapEnv.bodyOut; if(results != null) resultData = results.getProperty(0).toString(); return resultData; Using fiddler I got the following: Android request: <?xml version="1.0" encoding="utf-8"?> <v:Envelope xmlns:i="http://www.w3.org/2001/XMLSchema-instance" xmlns:d="http://www.w3.org/2001/XMLSchema" xmlns:c="http://schemas.xmlsoap.org/soap/encoding/" xmlns:v="http://schemas.xmlsoap.org/soap/envelope/"><v:Header /> <v:Body> <n0:CheckLogin id="o0" c:root="1" xmlns:n0="http://www.wegotcha.nl/servicehandler"> <n1:UserCredentials6 i:type="n1:UserCredentials6" xmlns:n1="Types"> <mail i:type="d:string">myemail</mail> <password i:type="d:string">myhashedpass</password> </n1:UserCredentials6> </n0:CheckLogin> </v:Body> </v:Envelope> Getting the following response: Procedure 'CheckLogin' not present My request produced by my WPF app looks completely different: <s:Envelope xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <UserCredentials6 xmlns="Types"> <mail>mymail</mail> <password>mypassword</password> </UserCredentials6> </s:Body> </s:Envelope> After googling my ass off I was not able to solve this problem by myself. It may be possible there are some weird things in my Java code because I changed a lot since. I hope you guys will be able to help me, thanks. EDIT: My webservice is of document/literal encoding style, after doing some research I found I should be able to use SoepEnvelope Instead of SoapSerializationEnvelope Though when I replace this I get an error before the try cache block, causing my app to crash. Error: 11-04 16:23:26.786: E/AndroidRuntime(26447): Caused by: java.lang.ClassCastException: org.ksoap2.serialization.SoapObject cannot be cast to org.kxml2.kdom.Node Which is caused by these lines: request.addSoapObject(UserCredentials); soapEnv.setOutputSoapObject(request); This may be a solution though, how do I go about this? I found nothing about using a SoapEnvelope instead of a SoapSerializationEnvelope except for this awesome tutorial: http://ksoap.objectweb.org/project/mailingLists/ksoap/msg00849.html

  • File Upload with HttpWebRequest doesn't post the file

  • impersonation and BackgroundWorker

    - by Lucian D
    Hello guys, I have a little bit of a problem when trying to use the BackgroundWorker class with impersonation. Following the answers from google, I got this code to impersonate public class MyImpersonation{ WindowsImpersonationContext impersonationContext; [DllImport("advapi32.dll")] public static extern int LogonUserA(String lpszUserName, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken); [DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)] public static extern int DuplicateToken(IntPtr hToken, int impersonationLevel, ref IntPtr hNewToken); [DllImport("advapi32.dll", CharSet = CharSet.Auto, SetLastError = true)] public static extern bool RevertToSelf(); [DllImport("kernel32.dll", CharSet = CharSet.Auto)] public static extern bool CloseHandle(IntPtr handle); public bool impersonateValidUser(String userName, String domain, String password) { WindowsIdentity tempWindowsIdentity; IntPtr token = IntPtr.Zero; IntPtr tokenDuplicate = IntPtr.Zero; if (RevertToSelf()) { if (LogonUserA(userName, domain, password, LOGON32_LOGON_INTERACTIVE, LOGON32_PROVIDER_DEFAULT, ref token) != 0) { if (DuplicateToken(token, 2, ref tokenDuplicate) != 0) { tempWindowsIdentity = new WindowsIdentity(tokenDuplicate); impersonationContext = tempWindowsIdentity.Impersonate(); if (impersonationContext != null) { CloseHandle(token); CloseHandle(tokenDuplicate); return true; } } } } if (token != IntPtr.Zero) CloseHandle(token); if (tokenDuplicate != IntPtr.Zero) CloseHandle(tokenDuplicate); return false; } } It worked really well until I've used it with the BackgroundWorker class. In this case, I've added a impersonation in the the code that runs asynchronously. I have no errors, but the issue I'm having is that the impersonation does not work when it is used in the async method. In code this looks something like this: instantiate a BGWorker, and add an event handler to the DoWork event: _bgWorker = new BackgroundWorker(); _bgWorker.DoWork += new DoWorkEventHandler(_bgWorker_DoWork); in the above handler, a impersonation is made before running some code. private void _bgWorker_DoWork(object sender, DoWorkEventArgs e) { MyImpersonation myImpersonation = new MyImpersonation(); myImpersonation.impersonateValidUser(user, domain, pass) //run some code... myImpersonation.undoImpersonation(); } the code is launched with BGWorker.RunWorkerAsync(); As I said before, no error is thrown, only that the code acts as if I did't run any impersonation, that is with it's default credentials. Moreover, the impersonation method returns true, so the impersonation took place at a certain level, but probably not on the current thread. This must happen because the async code runs on another thread, so there must be something that needs to be added to the MyImpersonation class. But what?? :) Thanks in advance, Lucian

  • Sort List C# in arbitrary order

    - by Jasper
    I have a C# List I.E. List<Food> x = new List<Food> () ; This list is populated with this class Public class Food { public string id { get; set; } public string idUser { get; set; } public string idType { get; set; } //idType could be Fruit , Meat , Vegetable , Candy public string location { get; set; } } Now i have this unsorted List<Food> list ; which has I.E. 15 elements. There are 8 Vegetable Types , 3 Fruit Types , 1 Meat Types , 1 Candy Types I would sort this so that to have a list ordered in this way : 1° : Food.idType Fruit 2° : Food.idType Vegetables 3° : Food.idType Meat 4° : Food.idType Candy 5° : Food.idType Fruit 6° : Food.idType Vegetables 7° : Food.idType Fruit //Becouse there isnt more Meat so i insert the //next one which is Candy but also this type is empty //so i start from begin : Fruit 8° : Food.idType Vegetables 9° : Food.idType Vegetables // For the same reason of 7° 10 ° Food.idType Vegetables ...... .... .... 15 : Food.idType Vegetables I cant find a rule to do this. Is there a linq or List.Sort instruction which help me to order the list in this way? Update i changed the return value of idType and now return int type instead string so 1=Vegetable , 2=Fruit , 3=Candy 4=Meat

  • MVC moq unit test the object before RedirecToAction()

  • Lists NotifyPropertyChanging

    - by Carlo
    Well BindingList and ObservableCollection work great to keep data updated and to notify when one of it's objects has changed. However, when notifying a property is about to change, I think these options are not very good. What I have to do right now to solve this (and I warn this is not elegant AT ALL), is to implement INotifyPropertyChanging on the list's type object and then tie that to the object that holds the list PropertyChanging event, or something like the following: // this object will be the type of the BindingList public class SomeObject : INotifyPropertyChanging, INotifyPropertyChanged { private int _intProperty = 0; private string _strProperty = String.Empty; public int IntProperty { get { return this._intProperty; } set { if (this._intProperty != value) { NotifyPropertyChanging("IntProperty"); this._intProperty = value; NotifyPropertyChanged("IntProperty"); } } } public string StrProperty { get { return this._strProperty; } set { if (this._strProperty != value) { NotifyPropertyChanging("StrProperty"); this._strProperty = value; NotifyPropertyChanged("StrProperty"); } } } #region INotifyPropertyChanging Members public event PropertyChangingEventHandler PropertyChanging; #endregion #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion public void NotifyPropertyChanging(string propertyName) { if (this.PropertyChanging != null) PropertyChanging(this, new PropertyChangingEventArgs(propertyName)); } public void NotifyPropertyChanged(string propertyName) { if (this.PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } public class ObjectThatHoldsTheList : INotifyPropertyChanging, INotifyPropertyChanged { public BindingList<SomeObject> BindingList { get; set; } public ObjectThatHoldsTheList() { this.BindingList = new BindingList<SomeObject>(); } // this helps notifie Changing and Changed on Add private void AddItem(SomeObject someObject) { // this will tie the PropertyChanging and PropertyChanged events of SomeObject to this object // so it gets notifies because the BindingList does not notify PropertyCHANGING someObject.PropertyChanging += new PropertyChangingEventHandler(someObject_PropertyChanging); someObject.PropertyChanged += new PropertyChangedEventHandler(someObject_PropertyChanged); this.NotifyPropertyChanging("BindingList"); this.BindingList.Add(someObject); this.NotifyPropertyChanged("BindingList"); } // this helps notifies Changing and Changed on Delete private void DeleteItem(SomeObject someObject) { if (this.BindingList.IndexOf(someObject) > 0) { // this unlinks the handlers so the garbage collector can clear the objects someObject.PropertyChanging -= new PropertyChangingEventHandler(someObject_PropertyChanging); someObject.PropertyChanged -= new PropertyChangedEventHandler(someObject_PropertyChanged); } this.NotifyPropertyChanging("BindingList"); this.BindingList.Remove(someObject); this.NotifyPropertyChanged("BindingList"); } // this notifies an item in the list is about to change void someObject_PropertyChanging(object sender, PropertyChangingEventArgs e) { NotifyPropertyChanging("BindingList." + e.PropertyName); } // this notifies an item in the list has changed void someObject_PropertyChanged(object sender, PropertyChangedEventArgs e) { NotifyPropertyChanged("BindingList." + e.PropertyName); } #region INotifyPropertyChanging Members public event PropertyChangingEventHandler PropertyChanging; #endregion #region INotifyPropertyChanged Members public event PropertyChangedEventHandler PropertyChanged; #endregion public void NotifyPropertyChanging(string propertyName) { if (this.PropertyChanging != null) PropertyChanging(this, new PropertyChangingEventArgs(propertyName)); } public void NotifyPropertyChanged(string propertyName) { if (this.PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } Sorry, I know this is a lot of code, which takes me back to my main point IT'S A LOT OF CODE to implement this. So my question is, does anyone know a better, shorter, more elegant solution? Thanks for your time and suggestions.

    Hello All: I have one application in which I want to pass data between Pages (Views) without sessions. Actually I want to apply some settings to all the pages using query string. For example if my link is like "http://example.com?data=test1", then I want to append this query string to all the link there after and if there is no query string then normal flow. I was thinking if there is any way that if we get the query string in any link for the web application then some application level user specific property can be set which can be used for subsequent pages.

  • MSMQ first Message.Body in queue is OK, all following Message.Body in queue are empty

    - by Andrew A
    I send a handful of identical (except for Id#, obviously) messages to an MSMQ queue on my local machine. The body of the messages is a serialized XElement object. When I try to process the first message in the queue, I am able to successfully de-serialize the Message.Body object and save it to file. However, when trying to process the next (or any subsequent) message, the Message.Body is absent, and an exception is thrown. I have verified the Message ID's are correct for the message attempting to be processed. The XML being serialized is properly formed. Any ideas? I am basing my code on the Microsoft MSMQ Book order sample found here: http://msdn.microsoft.com/en-us/library/ms180970%28VS.80%29.aspx // Create Envelope XML object XElement envelope = new XElement(env + "Envelope", new XAttribute(XNamespace.Xmlns + "env", env.NamespaceName) <snip> //Send envelope as message body MessageQueue myQueue = new MessageQueue(String.Format(@"FORMATNAME:DIRECT=OS:localhost\private$\mqsample")); myQueue.DefaultPropertiesToSend.Recoverable = true; // Prepare message Message myMessage = new Message(); myMessage.ResponseQueue = new MessageQueue(String.Format(System.Globalization.CultureInfo.InvariantCulture, @"FORMATNAME:DIRECT=TCP:192.168.1.217\private$\mqdemoAck")); myMessage.Body = envelope; // Send the message into the queue. myQueue.Send(myMessage,"message label"); //Retrieve messages from queue LabelIdMapping labelID = (LabelIdMapping)mqlistBox3.SelectedItem; System.Messaging.Message message = mqOrderQueue.ReceiveById(labelID.Id); The Message.Body value I see on the 1st retrieve is as expected: <?xml version="1.0" encoding="utf-8"?> <string>Some String</string> However, the 2nd and subsequent retrieve operations Message.Body is: "Cannot deserialize the message passed as an argument. Cannot recognize the serialization format." How does this work fine the first time but not after that? I have tried message.Dispose() after retrieving it but it did not help. Thank you very much for any help on this!

  • Get contact name from just the number

    - by user1190019
    Say i have an edit text and a button. In the edit text you would type a number and then when you hit the button it will either show the contact information or return with the name of that contact. I have tried all sorts of methods provided with no luck. The one i have successfully gotten the furthest with was the following... But i had no luck returning the name. Cursor phoneCursor = null; contactList = new HashMap<String,String>(); try{ Uri uContactsUri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI; String strProjection = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME; phoneCursor = getContentResolver().query(uContactsUri, null, null, null, strProjection); phoneCursor.moveToFirst(); String name = ""; String phoneNumber = ""; int nameColumn = phoneCursor.getColumnIndex(Phone.DISPLAY_NAME); int phoneColumn = phoneCursor.getColumnIndex(Phone.NUMBER); phoneCursor.moveToNext(); } } catch(Exception e){ Log.e("[SmsMain] getContactData", e.toString()); } finally{ if(phoneCursor != null){ phoneCursor.close(); phoneCursor = null; } } }

  • function to get the file name of an URL

    - by user262325
    Hello everyone I have some source code to get the file name of an url for example: http://www.google.com/a.pdf I hope to get a.pdf because the way to join 2 NSStrings I can get is 'appendString' which only for adding a string at right side, so I planned to check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop the checking, return string fdp.a , after that I change fdp.a to a.pdf source codes are below -(NSMutableString *) getSubStringAfterH : originalString:(NSString *)s0 { NSInteger i,l; l=[s0 length]; NSMutableString *h=[[NSMutableString alloc] init]; NSMutableString *ttt=[[NSMutableString alloc] init ]; for(i=l-1;i>=0;i--) //check each char one by one from the right side of string 'http://www.google.com/a.pdf', when it reach at the char '/', stop { ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; if([ttt isEqualToString:@"/"]) { break; } else { [h appendString:ttt]; } } [ttt release]; //below are to change the sequence of char in h // txt.edcba -> abcde.txt NSMutableString *h1=[[[NSMutableString alloc] initWithFormat:@""] autorelease]; for (i=[h length]-1;i>=0;i--) { NSMutableString *t1=[[NSMutableString alloc] init ]; t1=[h substringWithRange:NSMakeRange(i, 1)]; [h1 appendString:t1]; [t1 release]; } [h release]; return h1; } h1 can reuturn the coorect string a.pdf, but if it returns to the codes where it was called, after a while system reports 'double free * set a breakpoint in malloc_error_break to debug' I checked a long time and foudn that if I removed the code ttt=[s0 substringWithRange:NSMakeRange(i, 1)]; everything will be Ok (of course getSubStringAfterH can not returns the corrent result I expected.), no error reported. I try to fix the bug a few hours, but still no clue. Welcome any comment Thanks interdev

  • C#: File-size format provider

    - by Seb Nilsson
    Is there any easy way to create a class that uses IFormatProvider that writes out a user-friendly file-size? public static string GetFileSizeString(string filePath) { FileInfo info = new FileInfo(@"c:\windows\notepad.exe"); long size = info.Length; string sizeString = size.ToString(FileSizeFormatProvider); // This is where the class does its magic... } It should result in strings formatted something like "2,5 MB", "3,9 GB", "670 bytes" and so on.

  • Custom ViewEngine problem with ASP.NET MVC

    - by mare
    In this question jfar answered with his solution the problem is it does not work for me. In the method FindView() I have to somehow check if the View we are requesting is a ViewUserControl. Because otherwise I get an error saying: "A master name cannot be specified when the view is a ViewUserControl." This is my custom view engine code right now: public class PendingViewEngine : VirtualPathProviderViewEngine { public PendingViewEngine() { // This is where we tell MVC where to look for our files. /* {0} = view name or master page name * {1} = controller name */ MasterLocationFormats = new[] {"~/Views/Shared/{0}.master", "~/Views/{0}.master"}; ViewLocationFormats = new[] { "~/Views/{1}/{0}.aspx", "~/Views/Shared/{0}.aspx", "~/Views/Shared/{0}.ascx", "~/Views/{1}/{0}.ascx" }; PartialViewLocationFormats = new[] {"~/Views/{1}/{0}.ascx", "~/Views/Shared/{0}.ascx"}; } protected override IView CreatePartialView(ControllerContext controllerContext, string partialPath) { return new WebFormView(partialPath, ""); } protected override IView CreateView(ControllerContext controllerContext, string viewPath, string masterPath) { return new WebFormView(viewPath, masterPath); } public override ViewEngineResult FindView(ControllerContext controllerContext, string viewName, string masterName, bool useCache) { if (controllerContext.HttpContext.Request.IsAjaxRequest()) return base.FindView(controllerContext, viewName, "Modal", useCache); return base.FindView(controllerContext, viewName, "Site", useCache); } } The above ViewEngine fails on calls like this: <% Html.RenderAction("Display", "WidgetZoneV2", new { zoneslug = "left-default-zone" }); %> As you can see, I am providing Route values to my RenderAction call. The action I am rendering here is this: // Widget zone name is unique // GET: /WidgetZoneV2/{zoneslug} public ActionResult Display(string zoneslug) { zoneslug = Utility.RemoveIllegalCharacters(zoneslug); // Displaying widget zone creates new widget zone if it does not exist yet; so it prepares our page for // dropping of content widgets WidgetZone zone; if (!_repository.IsUniqueSlug(zoneslug)) zone = (WidgetZone) _repository.GetInstance(zoneslug); else { // replace slug with spaces to convert it into Title zone = new WidgetZone {Slug = zoneslug, Title = zoneslug.Replace('-', ' '), WidgetsList = new ContentList()}; _repository.Insert(zone); } ViewData["ContentItemsList"] = _repository.GetContentItems(); return View("WidgetZoneV2", zone); } I cannot use RenderPartial (at least I don't know how) the way I can RenderAction. To my knowledge there is no way to provide RouteValueDictionary to RenderPartial() like the way you can to RenderAction().

  • Java Runtime Exec for VBA script with arguments

    - by Holograham
    I am trying to use Runtime exec() to run a vba script with arguements. I am having trouble passing in the args. I think I need to use the String[] overloaded method for exec. Currently this works: String command = "cmd /c \"\\concat2.vbs\"" Process p = Runtime.getRuntime().exec(command); But I want to run that with arguments and if I do this String command = "cmd /c \"\\concat2.vbs\" " + arg1 + " " + arg2 where arg1 and arg2 are strings my program doesnt run (status = 1)

  • DataContractJsonSerializer produces list of hashes instead of hash

    - by Jacques
    I would expect a Dictionary object of the form: Dictionary<string,string> dict = new Dictionary<string,string>() {["blah", "bob"], ["blahagain", "bob"]}; to serialize into JSON in the form of: { "blah": "bob", "blahagain": "bob" } NOT [ { "key": "blah", "value": "bob" }, { "key": "blahagain", "value": "bob"}] What is the reason for what appears to be a monstrosity of a generic attempt at serializing collections? The DataContractJsonSerializer uses the ISerializable interface to produce this thing. It seems to me as though somebody has taken the XML output from ISerializable and mangled this thing out of it. Is there a way to override the default serialization used by .Net here? Could I just derive from Dictionary and override the Serialization methods? Posting to hear of any caveats or suggestions people might have.
