C# 事件 委託

 

學習一下事件 委託 (參考別人的部落格，自己學習一下)

using System;using System.Collections.Generic;using System.Linq;using System.Text;namespace ConsoleApplication1{   public class EventTest:EventArgs    {       private readonly string name;       public string Name       {           get { return name; }              }       public EventTest(){ }       public EventTest(string name)       {           this.name = name;       }    }   public class Notice   {       public delegate void NoticeEventHander(object sender, EventTest e);       public event NoticeEventHander Notic;       public void issue(string name)       {           if (Notic != null)           {               Notic(this, new EventTest(name));           }       }   }   public class XiaoYang   {       public static void SayXingQi(object sender,EventTest e)       {           Console.WriteLine(e.Name+"要放假了吧，呵呵");       }   }   public class XiaoLi   {       public static void SayFangJia(object sender,EventTest e)       {           Console.WriteLine("今天是"+e.Name+",到周末了，可以放鬆一下了，嘎嘎");       }   }   public class ComeOn   {       public static void Main(string[] args)       {           Notice notice = new Notice();           Console.WriteLine("請輸入今天星期幾？");           string name = Console.ReadLine();           if (name == "星期5")           {               notice.Notic += new Notice.NoticeEventHander(XiaoYang.SayXingQi);               notice.Notic += XiaoLi.SayFangJia;               notice.issue("星期5");               Console.ReadKey();           }       }   }}
