Net中委托之二多播委托

Net中委托之二多播委托

本篇主要讲解多播委托

1.多播委托的实例

 public class MyDelegate
    {
        private delegate int NoParameterWithReturn();//1.声明委托
        public static void Show()
        {
            NoParameterWithReturn method = new NoParameterWithReturn(ShowSomething);//2.委托的实例化
            //多播委托
            method += ShowSomething;//按顺序添加到方法列表
            method += ShowSomething;
            method += ShowSomething;
            method += ShowSomething;
            method -= ShowSomething;//从方法列表的尾部去掉且只去掉一个完全匹配
            Console.WriteLine("method.Invoke()结果是{0}", method.Invoke());//3.委托实例的调用
        }
        private static int ShowSomething()
        {
            Console.WriteLine("这里是ShowSomething");
            return 11;
        }
    }
 class Program
    {
        //多播委托
        static void Main(string[] args)
        {
            Console.WriteLine("欢迎来到流星小子博客学习");
            MyDelegate.Show();
            Console.Read();
        }
    }
