本文介绍了创建自定义事件的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
可以自定义事件的任何对象方法创建结果
。要做到这一点就我只是用的语法如下:??
myObject.myMethod + =新的EventHandler(myNameEvent);
下面的代码,促使这个问题:
私人无效btRunProcessAndRefresh_Click(对象发件人,EventArgs五)
{
myProcess =新工艺();
myProcess.StartInfo.FileName = @C:\ConsoleApplication4.exe
myProcess.Exited + =新的EventHandler(MyProcessExited);
myProcess.EnableRaisingEvents = TRUE;
myProcess.SynchronizingObject =这一点;
btRunProcessAndRefresh.Enabled = FALSE;
myProcess.Start();
}
解决方案分区>
是的,你可以这样做
或
的
公共类节拍器
{
公共事件TickHandler蜱;
公共EventArgs的= NULL;
公众委托无效TickHandler(节拍器男,EventArgs的);
公共无效启动()
{
,而(真)
{
System.Threading.Thread.Sleep(3000);
如果(蜱!= NULL)
{
蜱(这一点,E);
}
}
}
}
公共类监听器
{
公共无效订阅(节拍器米)
{
m.Tick + =新Metronome.TickHandler(HeardIt);
}
}
类测试
{
静态无效的主要()
{
节拍器M =新节拍器();
侦听器l =新监听器();
l.Subscribe(米);
m.Start();
}
}
Can a custom event be created for any object method?
To do this do I just use the following syntax?:
myObject.myMethod +=new EventHandler(myNameEvent);
The following code has prompted this question:
private void btRunProcessAndRefresh_Click(object sender,EventArgs e)
{
myProcess =new Process();
myProcess.StartInfo.FileName = @"c:\ConsoleApplication4.exe";
myProcess.Exited += new EventHandler(MyProcessExited);
myProcess.EnableRaisingEvents =true;
myProcess.SynchronizingObject =this;
btRunProcessAndRefresh.Enabled =false;
myProcess.Start();
}
解决方案
Yes you can do like this :
Creating advanced C# custom events
or
The Simplest C# Events Example Imaginable
public class Metronome
{
public event TickHandler Tick;
public EventArgs e = null;
public delegate void TickHandler(Metronome m, EventArgs e);
public void Start()
{
while (true)
{
System.Threading.Thread.Sleep(3000);
if (Tick != null)
{
Tick(this, e);
}
}
}
}
public class Listener
{
public void Subscribe(Metronome m)
{
m.Tick += new Metronome.TickHandler(HeardIt);
}
}
class Test
{
static void Main()
{
Metronome m = new Metronome();
Listener l = new Listener();
l.Subscribe(m);
m.Start();
}
}
