标准字符串std::string和System::String, CString之间的转换

1. std::string 转成System.String

#include <string>

#include <iostream>

using namespace System;

using namespace std;

int main() {

string str = "test";

cout << str << endl;

String^ str2 = gcnew String(str.c_str());

Console::WriteLine(str2);

// alternatively

String^ str3 = gcnew String(str.c_str());

Console::WriteLine(str3);
