(c++/cli) C++ using C# dll to get any enum member name

I'm using VS2010, I'm try to use a C# dll to get any enum member name in C++,

My C# dll source code:

namespace CSharpFuncion
{
    public class CSFun
    {
        public string GetEnumName(Enum en)
        {
            return Enum.GetName(typeof(Enum), en);
        }
    }
}

My C++ code

#using "CSharpFuncion.dll"
using namespace CSharpFuncion;
CSFun ^ csFun = gcnew CSFun;
cout << csFun->GetEnumName(MyTestEnum::E_A) << endl;

Error message:

cannot convert parameter from 'MyTestEnum'  to 'System::Enum ^'

How can I fix it?

Rather than 

public enum MyTestEnum
{
        E_A = 1,
        E_B = 2
};

You need to make it

public enum class MyTestEnum
{
        E_A = 1,
        E_B = 2
};

So just add the class keyword.

And change return Enum.GetName(typeof(Enum), en); to return en.ToString()

you have to give Enum.GetName(typeof(MyTestEnum ), 1); to get the name of value (E_A) in that enum
