Hi, guys!
I'm doing this, to see if one day I can print my arrays:

C++

// Case_2.cpp
//
#include <stdafx.h>
#include <string>
#include <iostream>
#include <fstream>
#include <istream>
#include "Form1.h"
#include <marshal_cppstd.h> // Also tried "marshal_cppstd.h"

using namespace Case_2;
//
int main ()
{
	void save_arrays ();
	return 0;
}
//
void save_arrays ()
{
   array<String^>^ my_array = gcnew array<String^> {"xxx", "yyy", "zzz"};
   for (int i = 0; i< 3; i++)
   {
      System::String^ clrString = my_array[i];
      std::string stdString = marshal_as<std::string>(clrString);
      std::cout << stdString << std::endl;
   }
   return;
}

ANY HELP?

Solution 1

Except if you have a good reason to do otherwise, you should use wide strings.

That is, you should use wstring and wcout.

Conversion will be easier and the code will properly works with characters that are not available in ANSI charset.

I have made a little change in your program to make it run by using visual studio 2010... Find the code snippet below:

XML

#include "stdafx.h"
#include <string>
#include <iostream>
#include <fstream>
#include <istream>
#include <msclr\marshal.h>
using namespace System;
using namespace Runtime::InteropServices;

void save_arrays();
int main(array<System::String ^> ^args)
{
    save_arrays();
    return 0;
}

void save_arrays ()
{
    array<String^>^ my_array = gcnew array<String^> {"xxx", "yyy", "zzz"};
    for (int i = 0; i< 3; i++)
    {
        System::String^ clrString = my_array[i];
        const char* chars = (const char*)(Marshal::StringToHGlobalAnsi(clrString)).ToPointer();
        std::string stdString = chars;
        std::cout << stdString << std::endl;
    }
    return;
}
