How do I define interfaces in managed C++/CLI

Question

Can we define interfaces in C++ using Visual Studio?

If yes, what would be an example of defining interfaces in C++?

Answer 1

C++ does not have a concept of "interface" per se. They are usually emulated with abstract classes with pure virtual functions. Moreover, classes are usually substituted with structs, since default access modifier for those is public. Hence,

struct IFoo
{
    virtual void Bar() = 0;
}

Also, see this.

Answer 2

In managed C++, this is the syntax for a managed interface.

using namespace System;

interface class IFoo
{
    String^ GetName();
};
