Hi Marvin,
What you wanted won't work because IDispatch is treated specially, it can't
be implemented in managed code like what you did (and many others tried the
same thing before).
There is another option though. You can implement the
System.Reflection.IReflect interface on your object to be working with COM.
See
http://msdn.microsoft.com/en-us/library/system.reflection.ireflect.aspx
And for .NET Framework 4.0 (the future), the new interface
ICustomQueryInterface will be helpful on this issue.
See
http://clrinterop.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=32350
Hope this helps.
Regards,
Jie Wang
