Question

I want to port the following code from c# to c++/cli:

class MyClass : IEnumerable<int> { ... }

I’ve tried

class ref class MyClass : IEnumerable<int>

but it doesn’t seem to be working.

Answer 1

C++ has multiple types of inheritance. Don’t forget to specify it, e.g.:

ref class MyClass : public IEnumerable<int>
{ };

In C++/CLI, I frequently find myself spelling out the full namespace in interface implementations. E.g.:

ref class MyClass :
    public MyCompany::MyProject::MyComponent::IMyInterface
{ };

If your class doesn’t actually implement the provided interface, you’ll also (of course) get an error. And you’ll want to remove the ^ from the class declaration. You’re inheriting from an interface, not from a GC Handle to an instance of that interface.
