   std::string str("Hello World");
   outValue = str;
}

谷歌搜索显示marshal_as(未经测试):

// marshal_as_test.cpp
// compile with: /clr
#include <stdlib.h>
#include <string>
#include <msclr\marshal_cppstd.h>

using namespace System;
using namespace msclr::interop;

int main() {
   std::string message = "Test String to Marshal";
   String^ result;
   result = marshal_as<String^>( message );
   return 0;
}

另请参阅封送概述.

来自MSDN:

#include <string>
#include <iostream>
using namespace System;
using namespace std;

int main() {
   string str = "test";
   String^ newSystemString = gcnew String(str.c_str());
}
