Question

I have following problem statement.

• Export a C++ class in the dll (un-managed).
• Create and use an object of this class in C# code.
  For the first part I have the classDLL.h as follows

“

#include <iostream>
__declspec(dllexport) 
class pABC{ 
    private: 
      int x; 
    public: 
      void func();
};

The respective cpp is also there. On compiling I get the dll.For thesecond part of the problem I am not getting how to proceed.

Thanks.

 [DllImport("pABC.dll", SetLastError = true, CharSet = CharSet.Auto)]
        private static extern void func();
