Having another go at some WCF stuff again.  
I have a C# method that accepts a type. I want to pass it an interface.

interface IMyInterface;  
public void DoStuff( Type t );

DoStuff( typeof(IMyInterface) );

> From the ruby side, I’m importing both IMyInterface and DoStuff from C#, I  
> just want to call the method from ruby.

When I do this:

do\_stuff( IMyInterface );

I get “can’t convert Module into System::Type”

If I try pass in a class, I get the similar “can’t convert Class into  
System::Type”

So, is there a way to get a .NET Type from a ruby object, particularly  
an  
interface/module? (it is a real .NET type as it’s loaded from a C# dll)

Any help is greatly appreciated. Thanks.

IMyInterface.to\_clr\_type should work.
