c# - 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();
