本文實例講述了C#自界說事宜監聽完成辦法。分享給年夜家供年夜家參考。詳細完成辦法以下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApp
{
 /// <summary>
 /// 界說事宜
 /// </summary>
 class CustomEvent
 {
  /// <summary>
  /// 界說拜托
  /// </summary>
  /// <param name="sender"></param>
  /// <param name="e"></param>
  public delegate void UserRequest(object sender, EventArgs e);
  /// <summary>
  /// 此拜托類型的事宜
  /// </summary>
  public event UserRequest OnUserRequest;
  public CustomEvent()
  {
   UserEventMonitor uem = new UserEventMonitor(this);
  }
  public void DoRun()
  {
   bool flag = false;
   do
   {
    Console.WriteLine();
    Console.WriteLine("請輸出：");
    string result = Console.ReadLine();
    if (result == "1")
    {
     if (OnUserRequest != null)
      OnUserRequest(this, new EventArgs());
    }
   } while (!flag);
  }
 }
 /// <summary>
 /// 事宜監聽
 /// </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!!");
  }
 }
 /// <summary>
 /// 挪用類
 /// </summary>
 public class Run
 {
  static void Main(string[] args)
  {
   CustomEvent cem = new CustomEvent();
   cem.DoRun();
   Console.ReadLine();
  }
 }
}
