Creating a Custom Event

Question

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();     } 

Answer 1

Declare the class containing the event:

class MyClass {     public event EventHandler MyEvent;      public void Method() {         OnEvent();     }      private void OnEvent() {         if (MyEvent != null) {             MyEvent(this, EventArgs.Empty);         }     } } 

Use it like this:

MyClass myObject = new MyClass(); myObject.MyEvent += new EventHandler(myObject_MyEvent); myObject.Method();
