c/c++回调c#委托:

worker.dll/main.h

extern "C"{     #define DLL __declspec(dllexport)    typedef void (__stdcall *Callback)(int);    DLL void DoWork(Callback callback);}

worker.dll/main.c

DLL void DoWork(Callback callback){    callback(1);}

c# Program.cs

using System;using System.Runtime.InteropServices;class Program{    [UnmanagedFunctionPointer(CallingConvention.StdCall)]    delegate void Callback(int value);      [DllImport("worker.dll")]    public static extern void DoWork([MarshalAs(UnmanagedType.FunctionPtr)]Callback callbackPointer);      [STAThread]    static void Main(string[] args)    {        // define a callback delegate        Callback callback =            (value) =>            {                Console.WriteLine("callback = {0}", value);            };        Console.ReadKey(true);        // call DoWork in C code        DoWork(callback);         Console.WriteLine();        Console.ReadKey(true);    }}
