什么时链式委托？请举个简单例子。 就是多点委托。

publicdelegate void stopDelegate();

publicstatic void stopTV() {

      Console.WriteLine("关闭电视机");

} 

publicstatic void stopLight()

{

      Console.WriteLine("关灯");

}

publicstatic void stopFan()

{

      Console.WriteLine("关电扇");

} 

staticvoid Main(string[] args)

{

         stopDelegate stop = stopTV;    

         stopDelegate stop2 = stopLight;

         stopDelegate stop3 = stopFan;

         stopDelegate stopHead = stop + stop2 +stop3;

         //链表头    

         stopHead();

}
