Sure! You can declare an event using the event keyword. For example: public event EventHandler MyEvent;. To raise it, you can use MyEvent?.Invoke(this, EventArgs.Empty);.
What is the difference between an event and a delegate?
A delegate is a type that represents references to methods with a specific parameter list and return type. An event is a special kind of delegate that is used to provide notifications.
