Googling reveals marshal_as (untested):

// marshal_as_test.cpp
// compile with: /clr
#include <stdlib.h>
#include <string>
#include <msclrmarshal_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;
}
