本文实例讲述了C#自定义事件监听实现方法。分享给大家供大家参考。具体实现方法如下：
?| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 |
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!!");
}
}
/// <summary>
/// 调用类
/// </summary>
public class Run
{
static void Main(string[] args)
{
CustomEvent cem = new CustomEvent();
cem.DoRun();
Console.ReadLine();
}
}
}
