Event declaration:
public event EventHandler<EventArgsType> EventName;
Event handler declaration using lambda operator => and subscribing to the event:
EventName += (obj, eventArgs) => { /* Handler logic */ };
Event handler declaration using delegate anonymous method syntax:
EventName += delegate(object obj, EventArgsType eventArgs) { /* Handler Logic */ };
Declaration & subscription of an event handler that does not use the event's parameter, and so can use the above syntax without needing to specify parameters:
EventName += delegate { /* Handler Logic */ }
Invoking the event:
EventName?.Invoke(SenderObject, EventArguments);
