I think you technically can create events without a delegate, please below link. https://social.msdn.microsoft.com/Forums/en-US/216893be-27b2-49a8-b563-3be1cd875049/can-events-exist-without-delegates?forum=clr However, delegates are used to pass information from where the event was raised. Without it, the program doesn't know where the event was called from and what information to pass. Check below link for good introduction. https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/keywords/event For clarification, Please check this thread. https://stackoverflow.com/questions/48441813/can-i-have-only-event-without-delegate A delegate normally describes a function type. An event is a hook where registered functions matching a given function type are called when the event occurs.

A delegate basically describes a function type. An event is a hook where registered functions matching a given function type are called when the event occurs. Putting together these two simplified definitions, a delegate is also a descriptor for an event, therefore you cannot have an event without a related delegate. Anyway, you are not forced to declare a new delegate for every event you declare. Instead, you can use any of the preexisting delegates such as EventHandler , EventHandler or even any of the Action overloads, choosing in the one that fits you best in each case.
