C#调用C++ dll，并向调用的函数传递“函数指针”

SocketBLL（C++dll项目）：

BLL.h文件：

#pragma once
#include <Windows.h>
typedef void(*MsgManagement)(int);
MsgManagement MsgManage;
HANDLE h;
DWORD WINAPI RecieveTransientMsg(LPVOID pParam);
extern "C" _declspec(dllexport) void _stdcall Start(MsgManagement p);
extern "C" _declspec(dllexport) void _stdcall Wait();

BLL.cpp文件：

#include "BLL.h"

DWORD WINAPI RecieveTransientMsg(LPVOID pParam)
{
((MsgManagement)pParam)(2);
return 0;
}
extern "C" _declspec(dllexport) void _stdcall Start(MsgManagement p)
{
h = CreateThread(NULL, 0, RecieveTransientMsg, p, 0, NULL);
}
extern "C" _declspec(dllexport) void _stdcall Wait()
{
::WaitForSingleObject(h,INFINITE);
}

ConsoleServer(C#项目)：

Program.cs文件：

命名空间：using System.Runtime.InteropServices;

class Program
{
public delegate void MsgManagement(int t);

[DllImport("SocketBLL.dll")]
public extern static void Start(MsgManagement callback);
[DllImport("SocketBLL.dll")]
public extern static void Wait();

static void myCout(int i)
{
Console.WriteLine(i);
}

static MsgManagement callback;
static void Main(string[] args)
{
callback = myCout;
Start(myCout);
Wait();
Console.WriteLine(1);
return;
}
}
