C#的代理（delegate），可以理解为VC的一个函数指针

C#使用代理具体的实现方法：

public delegate void EventHandler(byte[] readByte,int readNum);
public class CommPort
{
public EventHandler readHandle; //使用代理
public void SetReceiveFunc(EventHandler setHandle)

readHandle =setHandle;
}

}

public class test
{
public static void Main()
{
CommPort comInstanse= new CommPort();
comInstanse.SetReceiveFunc(new EventHandler(handleByte));
}

void handleByte (byte[] readByte,int readNum)
{

}

}

若在VC中使用指针函数
typedef void (*EventHandler)(LPVOID,void*,DWORD);
public class CommPort
{
public EventHandler readHandle; //使用函数指针
public void SetReceiveFunc(EventHandler setHandle)
{
readHandle =setHandle;
}

}

public class test
{
public static void Main()
{
CommPort comInstanse= new CommPort();
comInstanse.SetReceiveFunc(new EventHandler(handleByte));

}

void handleByte (byte[] readByte,int readNum)
{

}

}
