在C ++ / CLI中，您可以具有静态函数（带有本机C签名，可以用作C库的回调） ），调用托管代表：

In C++/CLI, you can have static functions (with native C signature, which can work as a callback from a C library), calling managed delegates:

// MyDispatcherClass.h
#pragma once

public delegate void MyDelegateType();

public ref class MyDispatcherClass
{
public:
    static MyDelegateType^ MyDelegate;
};

static void MyCallback(/*...*/)
{
    if (MyDispatcherClass::MyDelegate != nullptr)
        MyDispatcherClass::MyDelegate(/* do some type mapping here if needed */);
}


// MyDispatcherClass.cpp: 
#include "stdafx.h"
#include "MyDispatcherClass.h"

因此在C库中注册 MyCallback ，将C＃委托注册为 MyDispatcherClass :: MyDelegate 完成。

So register MyCallback at your C library, register your C# delegate to MyDispatcherClass::MyDelegate and you are done.
