How to invoke method for web services

From the previous post, this is to show you how easy you can invoke method from web services. The code below is very short just 3 lines. There are only few steps, 1st create object using Object class, then call the Activator class for creating instance of service.

//Invoke Method
Object obj = Activator.CreateInstance(service);
Object response = t.Invoke(obj, param1);

return response;

Please try to code this and if you have any questions please comment here and I would be very happy to answer your questions.

Dynamic Invocation in Wsdl Reader Class

This is one of important code in the AutoWS program, DynamicInvocation. I use this one than hybernating. You can see sample of the class and function below.

WsdlReader class:
DynamicInvocation

StringWriter stringWriter = new StringWriter(System.Globalization.CultureInfo.CurrentCulture);
Microsoft.CSharp.CSharpCodeProvider prov = new Microsoft.CSharp.CSharpCodeProvider();
prov.GenerateCodeFromNamespace(nameSpace, stringWriter, new CodeGeneratorOptions());

// Compile the assembly with the appropriate references
string[] assemblyReferences = new string[2] { "System.Web.Services.dll", "System.Xml.dll" };
CompilerParameters param = new CompilerParameters(assemblyReferences);
param.GenerateExecutable = false;
param.GenerateInMemory = true;
param.TreatWarningsAsErrors = false;
param.WarningLevel = 4;

CompilerResults results = new CompilerResults(new TempFileCollection());
results = prov.CompileAssemblyFromDom(param, codeCompileUnit);
Assembly assembly = results.CompiledAssembly;
service = assembly.GetType(sdName);

methodInfo = service.GetMethods();

next chapter I will write sample how to use this class in the AutoWS program.
