C# Interfaces in C++?

[Chris]

Hello,

I'm creating a small plugin interface for my future .NET DLL's. This
interface is written in C# primarily for C# dlls. However, in one
particular instance, I have to plugin a C++ dll. How do I use the following
interface that is written in C# in C++ (I have limited experience with VC++
and am just learning .net)?

Thanks in advance!

Chris

using System;
namespace PlugIn

{

public interface IPlugin

{

Int32 Add(Int32 a, Int32 b);

string Name{get;set;}

IPluginHost Host{get;set;}

}

/// <summary>

/// The host

/// </summary>

public interface IPluginHost

{

bool Register(IPlugi n ipi);

}

}

In the .h file of the C++ project, do I just add the ": public IPlugin"
clause to the class definition? What else is necessary?

// test.h
#pragma once

using namespace System;

namespace test

{

public __gc class Class1 : public IPlugin

{

// TODO: Add your methods for this class here.

};

}

Chris,

The only way to access this in C++ is to either use Managed Extensions
in C++, in which case you have access to all unmanaged types, or you will
have to export the interface as a COM interface, and have your C++ code
create a COM component that implements the interface.

Hope this helps.

Thanks Nicholas, I'll give it a try.
