易采站长站为您分析C#自定义事件监听实现方法,涉及C#事件监听的实现技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了C#自定义事件监听实现方法。。具体实现方法如下:
- using System; using System.Collections.Generic;
- using System.Linq; using System.Text;
- namespace ConsoleApp {
- /// <summary> /// 定义事件
- /// </summary> class CustomEvent
- { /// <summary>
- /// 定义委托 /// </summary>
- /// <param name="sender"></param> /// <param name="e"></param>
- public delegate void UserRequest(object sender, EventArgs e); /// <summary>
- /// 此委托类型的事件 /// </summary>
- public event UserRequest OnUserRequest; public CustomEvent()
- { UserEventMonitor uem = new UserEventMonitor(this);
- } public void DoRun()
- { bool flag = false;
- do {
- Console.WriteLine(); Console.WriteLine("请输入:");
- string result = Console.ReadLine(); if (result == "1")
- { if (OnUserRequest != null)
- OnUserRequest(this, new EventArgs()); }
- } while (!flag); }
- } /// <summary>
- /// 事件监听 /// </summary>
- class UserEventMonitor {
- public UserEventMonitor(CustomEvent cem) {
- // cem.OnUserRequest += ShowMessage; cem.OnUserRequest += delegate
- { Console.WriteLine("hello word!!");
- }; }
- public void ShowMessage(object sender, EventArgs e) {
- Console.WriteLine("hello word!!"); }
