Delegates

I'm always confusing this...

For future reference;

• Declare the delegate which defines the "class" for the event you're going to raise - with parameters etc
• Declare the event - of type "delegate" - with the parameters.
• Write a private function to handle calling the event - check for null event object first.
• Then just call the private function whenever you want to raise the event.

public delegate void EventNameHandler(type paramName);

then;

public event EventNameHandler EventName;

then;

private void OnEventName(type param)
{
if (EventName != null)
    {
        EventName(param);
    }
}

Then, in the consuming class;

classWithTheEvent.EventName += new EventNameHandler(localFunctionName);
