Calling a web service from within a DLL

[paul1664]

Hi,

I am trying to call a web service from within a dll, with that dll
being loaded and called dynamically.

eg.

Assembly assembly = Assembly.LoadFile(@"C:\path\myfile.dll");
Type type = assembly.GetType("myfile.Class1");
object instance = Activator.CreateInstance(type);

object returnvalue = type.InvokeMember("MyMethod",
BindingFlags.InvokeMethod | BindingFlags.Default,
null, instance, null);

The assembly, type and instance are all populated correctly and I can
call other methods just fine, but as soon as I invoke "MyMethod" as
above, which calls a web service internally, it fails with a casting
error. Monitoring the web server shows that the web service was called
successfully but the response was incorrectly cast. Any ideas?

I know that the code within my dll is correct because if I reference
and call the method directly (eg. myfile.Class1 test= new
myfile.Class1(); test.MyMethod(); ) then the web service gets called
and completes successfully.

Hope someone can help,

Regards, Paul.

Forgot to say... VS2005!

I've done some subsequent testing and found out that if I call it from
a Web Application Project
(http://msdn.microsoft.com/vstudio/de...sp#wapp_topic4)
then it works. Its only when I call from a Web Site Project (the
default with VS2005) it fails.
