Example

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);
Creating cancelable event
