C ++到C＃事件处理 [英] C++ to C# event handling

问题描述

所以，我已经得到了它在我的 C＃ WinForm应用程序，我把我的 C ++ CLI MFC DLL 库。

So I've got my C# WinForm Application, from it I call my C++ CLI MFC dll library.

但也有一些的活动在我的C ++库，即使这样的事件发生在该库的原生（非CLI）的一部分。而我需要从我的C＃应用​​程序调用一些代码，并得到了一些数据，也许就在那里对本次活动

But there are some events on my C++ library, even this events happens in native (non-CLI) part of this library. And I need to call some code from my C# application and get some data maybe right there on this event.

所以，当这本机的功能是从客户端名为：

so when this native function is called from client side :

bool __stdcall ClassName::WorkQuery()
{
         ......
        switch(pp->code)
        {
        case READCOMPLEX:
                       ..........

我需要从C＃把数据的所以我需要以某种方式注册此作为事件。

I need to bring the Data from C# so I need to register this as event somehow.

推荐答案

所以，问题是你需要在响应MFC事件（或C ++回调）上运行的C＃代码，对吧？

So the problem is you need to run C# code in response to MFC event (or C++ callback), right?

为什么你不能只是注册一个原生处理器原生事件/回调，然后只调用.NET的事件，可以从C＃来消耗。

Why can't you just register a native handler to the native event/callback, which then just invokes a .NET event, which can be the consumed from C#.
