   Hi, Crows.
   I read your post — Dynamically Invoke Web Service At Runtime, it is very helpful to me. thanks

   here, i met a problem. i hope if you have time, you can unscramble my confusion. i’m very appreciated about your help and your time.

   I write a function like this:

   public struct Test
   {
   public string str;
   public int num;
   }

   [WebMethod]

   public string TestFun(Test ts)
   {
   return ts.str + ts.num.ToString();
   }

   Then, i found this time, i got 2 AvailableServices ,
   one is “MyService”, and the other is “Test”.

   also, I found for service “Test”, there are 4 corresponding methods : get_str, set_str, get_num, set_num

   Do you know how to invoke the function TestFun???
   Thanks.

   this is the codebehind in my webservicegeneric.asmx…..

   Public Function InvokeMethod(ByVal webServiceUri As String, ByVal serviceName As String, ByVal methodName As String, ByVal ParamArray args As Object()) As String
   Dim args_result() As [Object]

   webServiceAssembly = BuildAssemblyFromWSDL(New Uri(webServiceUri))
   Dim obj As Object = webServiceAssembly.CreateInstance(serviceName)
   Dim methods As New List(Of String)
   Dim type As Type = obj.[GetType]()
   ‘For Each minfo As MethodInfo In type.GetMethods(BindingFlags.Instance Or BindingFlags.[Public] Or BindingFlags.DeclaredOnly)
   ‘ methods.Add(minfo.Name)
   ‘Next
   Dim result As String
   result = type.InvokeMember(methodName, BindingFlags.InvokeMethod, Nothing, obj, args)
   Return result
   End Function
