  Suppose I have an anonymous class instance var foo = new { A = 1, B = 2}; Is there a quick way to generate a NameValueCollection? I would like to achieve the same result as the code below, without knowing the anonymous type's properties in advance. NameValueCollection formFields = new NameValueCollection(); formFields["A"] = 1; formFields["B"] = 2;

  - by Tarik

  Hello people, Lets say we have a code portion like this : IProduct product = ProductCreator.CreateProduct(); //Factory Method we have here SellThisProduct(product); //... private void SellThisProduct(IProduct product) { //..do something here } //... internal class Soda : IProduct {} internal class Book : IProduct {} How can I infer which product is actually passed into SellThisProduct() method in the method? I think if I say GetType() or something it will probably return the IProduct type. Thanks...

• Optional non-system type parameters

  - by Courtney de Lautour

  C#4.0 obviously brings optional parameters (which I've been waiting for, for quite some time). However it seems that because only system types can be const that I cannot use any class/struct which I have created, as an optional param. Is there a some way which allows me to use a more complex type as an optional parameter. Or is this one of the realities that one must just live with?

• Python3 function annotations for type hinting versus Boo

  - by b0lt

  I've started on a medium-sized project in python, and I decided to use python 3 because I'm not using any large external libraries and py3k has some nice new syntactic sugar and more importantly function annotations. However, it seems like none of WingIDE, Pydev, or pycharm actually have any support for type hinting using function annotations. If I want something resembling static typing in python, is switching to boo a reasonable option?

I am using rails atom builder to create a valid atom feed, but when I use xml.tag!("activity:object-type", "http://activitystrea.ms/schema/1.0/person") the atom feed goes blank.On seeing the source I find the correct xml format from what I have found out the ":object" is giving the problem.

  I want to get the type of NSNumber instance. I found out on http://www.cocoadev.com/index.pl?NSNumber this: NSNumber *myNum = [[NSNumber alloc] initWithBool:TRUE]; if ([[myNum className] isEqualToString:@"NSCFNumber"]) { // process NSNumber as integer } else if ([[myNum className] isEqualToString:@"NSCFBoolean"]) { // process NSNumber as boolean } Ok, but this doesn't work, the [myNum className] isn't recognized by the compiler.

  In Core Data, if I have a Person entity is there any difference between: NSManagedObject *aPerson = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:[self managedObjectContext]]; or Person *aPerson = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:[self managedObjectContext]]; Should aPerson be of type Person or NSManagedObject?
