i am receiving the follwing error when i am invoking a custom object "Object of type 'customObject' cannot be converted to type 'customObject'."

Following is the scenario when i am getting the error

i am invoking a method in a dll dynamically.

Load an assembly

CreateInstance....

calling MethodInfo.Invoke() passing int, string as a parameter for my method is working fine => No exceptions are thrown.

But if I try and pass a one of my own custom class objects as a parameter, then I get an ArgumentException exception, and it is not either an ArgumentOutOfRangeException or ArgumentNullException.

"Object of type 'customObject' cannot be converted to type 'customObject'."

I am doing this in a web application.

The class file containing the method is in a different proj . also the custom object is a sepearte class in the same file.

there is no such thing called a static aseembly in my code. I am trying to invoke a webmethod dynamically. this webmethod is having the customObject type as an input parameter. So when i invoke the webmethod i am dynamically creating the proxy assembly and all. From the same assembly i am trying to create an instance of the cusotm object assinging the values to its properties and then passing this object as a parameter and invoking the method. everything is dynamic and nothing is created static.. :(

add reference is not used. Following is a sample code i tried to create it

public static object CallWebService(string webServiceAsmxUrl, string serviceName, string methodName, object[] args) 
    { 
        System.Net.WebClient client = new System.Net.WebClient(); 
        //-Connect To the web service 
        using (System.IO.Stream stream = client.OpenRead(webServiceAsmxUrl + "?wsdl")) 
        { 
            //--Now read the WSDL file describing a service. 
            ServiceDescription description = ServiceDescription.Read(stream); 
            ///// LOAD THE DOM ///////// 
            //--Initialize a service description importer. 
            ServiceDescriptionImporter importer = new ServiceDescriptionImporter(); 
            importer.ProtocolName = "Soap12"; // Use SOAP 1.2. 
            importer.AddServiceDescription(description, null, null); 
            //--Generate a proxy client. importer.Style = ServiceDescriptionImportStyle.Client; 
            //--Generate properties to represent primitive values. 
            importer.CodeGenerationOptions = System.Xml.Serialization.CodeGenerationOptions.GenerateProperties; 
            //--Initialize a Code-DOM tree into which we will import the service. 
            CodeNamespace nmspace = new CodeNamespace(); 
            CodeCompileUnit unit1 = new CodeCompileUnit(); 
            unit1.Namespaces.Add(nmspace); 
            //--Import the service into the Code-DOM tree. This creates proxy code 
            //--that uses the service. 
            ServiceDescriptionImportWarnings warning = importer.Import(nmspace, unit1); 
            if (warning == 0) //--If zero then we are good to go 
            { 
                //--Generate the proxy code  
                CodeDomProvider provider1 = CodeDomProvider.CreateProvider("CSharp"); 
                //--Compile the assembly proxy with the appropriate references 
                string[] assemblyReferences = new string[5] { "System.dll", "System.Web.Services.dll", "System.Web.dll", "System.Xml.dll", "System.Data.dll" }; 
                CompilerParameters parms = new CompilerParameters(assemblyReferences); 
                CompilerResults results = provider1.CompileAssemblyFromDom(parms, unit1); 
                //-Check For Errors 
                if (results.Errors.Count > 0) 
                { 
                    StringBuilder sb = new StringBuilder(); 
                    foreach (CompilerError oops in results.Errors) 
                    { 
                        sb.AppendLine("========Compiler error============"); 
                        sb.AppendLine(oops.ErrorText); 
                    } 
                    throw new System.ApplicationException("Compile Error Occured calling webservice. " + sb.ToString()); 
                } 
                //--Finally, Invoke the web service method  
                Type foundType = null; 
                Type[] types = results.CompiledAssembly.GetTypes(); 
                foreach (Type type in types) 
                { 
                    if (type.BaseType == typeof(System.Web.Services.Protocols.SoapHttpClientProtocol)) 
                    { 
                        Console.WriteLine(type.ToString()); 
                        foundType = type; 
                    } 
                } 

                object wsvcClass = results.CompiledAssembly.CreateInstance(foundType.ToString()); 
                MethodInfo mi = wsvcClass.GetType().GetMethod(methodName); 
                return mi.Invoke(wsvcClass, args); 
            } 
            else 
            { 
                return null; 
            } 
        } 
    } 

I cant find anything static being done by me.

any help is greatly appreciated.
