推荐答案

来自 MSDN:

#include <iostream>
#include <stdlib.h>
#include <string>

using namespace std;
using namespace System;

int main()
{
    char *orig = "Hello, World!";
    cout << orig << " (char *)" << endl;

    // Convert to a wchar_t*
    size_t origsize = strlen(orig) + 1;
    const size_t newsize = 100;
    size_t convertedChars = 0;
    wchar_t wcstring[newsize];
    mbstowcs_s(&convertedChars, wcstring, origsize, orig, _TRUNCATE);
    wcscat_s(wcstring, L" (wchar_t *)");
    wcout << wcstring << endl;
}
