1. #include <string>  
2. #include <iostream>  
3. using namespace System;  
4. using namespace std;

6. int main() {  
7.    string str = "test";  
8.    cout << str << endl;  
9.    String^ str2 = gcnew String(str.c_str());  
10.    Console::WriteLine(str2);  
11.   
12.    // alternatively  
13.    String^ str3 = gcnew String(str.c_str());  
14.    Console::WriteLine(str3);
