How to Efficiently Convert Between System::String and std::string in C   .NET?

Using the Marshal Class to Convert between System::String and std::string

Translating between System::String in C .NET and std::string in C can be a common task. The marshal_context class provided by MS provides a clean and efficient way to achieve this.

Syntax:

<code class="CPP">msclr::interop::marshal_context context;
std::string standardString = context.marshal_as<std::string>(managedString);</code>

Example:

<code class="CPP">#include "stdafx.h"
#include <string>

#include <msclr/marshal_cppstd.h>

using namespace System;

int main(array<System::String ^> ^args)
{
    System::String^ managedString = "test";

    msclr::interop::marshal_context context;
    std::string standardString = context.marshal_as<std::string>(managedString);

    return 0;
}</code>

Benefits:

  • The marshal_context class provides additional safety and exception handling compared to manual memory management.
  • The syntax is concise and easy to read.

Alternative Conversions

The MSDN article referenced by the answer also provides other conversion methods, such as:

  • Using COM interop marshalling functions like SysStringToBSTR.
  • Using the MarshalAs attribute with platform invoke functions.
