C#自定义事件监听实现方法
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：
usingSystem;
usingSystem.Collections.Generic;
usingSystem.Linq;
usingSystem.Text;
namespaceConsoleApp
{
///<summary>
///定义事件
///</summary>
classCustomEvent
{
///<summary>
///定义委托
///</summary>
///<paramname="sender"></param>
///<paramname="e"></param>
publicdelegatevoidUserRequest(objectsender,EventArgse);
///<summary>
///此委托类型的事件
///</summary>
publiceventUserRequestOnUserRequest;
publicCustomEvent()
{
UserEventMonitoruem=newUserEventMonitor(this);
}
publicvoidDoRun()
{
boolflag=false;
do
{
Console.WriteLine();
Console.WriteLine("请输入：");
stringresult=Console.ReadLine();
if(result=="1")
{
if(OnUserRequest!=null)
OnUserRequest(this,newEventArgs());
}
}while(!flag);
}
}
///<summary>
///事件监听
///</summary>
classUserEventMonitor
{
publicUserEventMonitor(CustomEventcem)
{
//cem.OnUserRequest+=ShowMessage;
cem.OnUserRequest+=delegate
{
Console.WriteLine("helloword!!");
};
}
publicvoidShowMessage(objectsender,EventArgse)
{
Console.WriteLine("helloword!!");
}
}
///<summary>
///调用类
///</summary>
publicclassRun
{
staticvoidMain(string[]args)
{
CustomEventcem=newCustomEvent();
cem.DoRun();
Console.ReadLine();
}
}
}
希望本文所述对大家的C#程序设计有所帮助。
