How to receive strings from C# in Visual-C++ based .net DLL?

Question

In C++ (using clr) I have this code:

#include "stdafx.h"
##include <Windows.h>
#include <string>
#include <windows.h>

namespace NSST
{
  public ref class Wrapper
  {
 public:
     Wrapper() {}
    static void init_1(std::string a, std::string b){}
     static void init_2(){}
  };
};

But in .net C# I see only one function init_2. How do I make init_1 visible in .net?

You can't use std::string, you should use System::String^:

static void init_1(System::String^ a, System::String^ b);

Updated link for the said article: buffered.io/posts/net-systemstring-to-ansi-char (would be great if old comments were editable too).
