[ASP.NET] 事件与委托的处理
放一段C#中基本的利用事件与委托的程序,执行平台 .net控制台程序
1using System;
2using System.Collections.Generic;
3using System.Text;
4
5namespace practise2
6{
7 public delegate void DelHandler( object sender ); //委托的申明
8 class Program
9 {
10 static void Main(string[] args)
11 {
12 Heater heater = new Heater();
13 }
14 }
15 public class Heater
16 {
17 public event DelHandler temEvent;
18 public Heater()
19 {
20 temEvent += new DelHandler(Alarm.MakeAlert); //事件与委托的绑定,委托与处理函数绑定
21 System.Threading.Thread.Sleep(1000);
22 temEvent(this); //事件的触发,这里规定刚开始实例化就触发
23 }
24
25 }
26
27
28 public class Alarm
29 {
30 static public void MakeAlert(object sender) //处理函数,参数要和委托申明一样
31 {
32 Display.showMessage();
33 }
34 }
35 public class Display
36 {
37 static public void showMessage()
38 {
39 Console.Write("KAILE");
40 }
41 }
42}
