创建自定义事件 [英] Creating a Custom Event

问题描述

可以为任何对象方法创建自定义事件吗？

为此，我只需使用以下语法：

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);

以下代码提示了以下问题：

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();
    }

推荐答案

是的，你可以这样做：

创建高级C＃自定义事件

或

最简单的C＃事件示例可想象

 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();
        }
    }
