++ C＃和C之间的进程间通信 [英] Interprocess communication between C# and C++

问题描述

我正在写一个僵尸的游戏，其中有一个C ++ API接口（即在一段cpp的方法DLL被调用由事件发生时，该dll可以调用后面的比赛方法来触发动作游戏）。

I'm writing a bot for a game, which has a C++ API interface (ie. methods in a Cpp dll get called by the game when events occur, the dll can call back methods in the game to trigger actions).

我真的不希望我写在C ++中的机器人，我是一个非常有经验的C＃程序员，但我没有C ++的经验都没有。因此，显而易见的解决方案是使用IPC发送事件给一个C＃程序，并发送行动回到C ++的，这样我需要用C写++是调用方法和发送事件的基本框架。

I don't really want to write my bot in C++, I'm a fairly experienced C# programmer but I have no C++ experience at all. So, the obvious solution is to use ipc to send event to a C# program, and send actions back to the C++ one, that way all I need to write in C++ is a basic framework for calling methods and sending events.

什么是做到这一点的最好方法是什么？样品code会大大AP preciated，因为我没有必须学习C ++在这一点上特别的愿望！

What would be the best way to do this? Sample code would be greatly appreciated as I no have particular desire to learn C++ at this point!

推荐答案

一种解决方案是创建一个托管C ++类库与普通的 __ declspec（dllexport）的其中要求管理功能方法引用C＃类库。

One solution is to create a managed C++ class library with regular __declspec(dllexport) functions which call managed methods in a referenced C# class library.

示例 - C ++ code。在托管C ++项目文件：

Example - C++ code file in managed C++ project:

#include "stdafx.h"

__declspec(dllexport) int Foo(int bar) 
{
    csharpmodule::CSharpModule mod;
    return mod.Foo(bar);
}

C＃模块（在溶液中单独的项目）：

C# Module (separate project in solution):

namespace csharpmodule
{
    public class CSharpModule
    {
        public int Foo(int bar)
        {
            MessageBox.Show("Foo(" + bar + ")");
            return bar;
        }
    }
}

请注意，我证明，这是通过使用 System.Windows.Forms.MessageBox.Show 调用实际.NET调用。

Note that I am demonstrating that this is an actual .NET call by using a System.Windows.Forms.MessageBox.Show call.

样品基本（非CLR）Win32控制台应用程序：

Sample basic (non-CLR) Win32 console application:

__declspec(dllimport) int Foo(int bar);

int _tmain(int argc, _TCHAR* argv[])
{
    std::cout << Foo(5) << std::endl;
    return 0;
}

记住链接与的.lib 从托管C ++项目的生成生成的文件中Win32控制台应用程序。

Remember to link the Win32 console application with the .lib file resulting from the build of the managed C++ project.
