CreateInstance problem

[Hans Berende]

Hi all

I have read the posting of Chris Bamford, but I still get the problem...

Here are some pieces of code

file IPlugin.cs
public interface IPlugi

string SayHi()

file Class1.c
public class Class1: IPlugi

string IPlugin.SayHi(

return "Hi"

These excerpts are compiled into test.dll

file form1.c
Assembly cAssembly = Assembly.LoadFrom(@"C:\test.dll")
foreach(Type cType in cAssembly.GetTypes()

if(cType.IsClass

if(cType.GetInterface("IPlugin") != null

test.IPlugin Plugin = (test.IPlugin)Activator.CreateInstance(cType)
textBox1.Text = Plugin.SayHi()


Can anybody tell me why I keep getting a System.InvalidCastException in

test.IPlugin Plugin = (test.IPlugin)Activator.CreateInstance(cType)
??

Thanx in advance
Hans
