When to use callbacks instead of events in c#?

Question

Forgive me if this a stupid question, I admit I haven\'t thought about it much.

But when would you favour using a callback (i.e, passing in a Func or Action), as oppo

Answer 1

I would use Func or Action when I am going to call the function once or use a Lambda expression.

Events can be registered more than once which sometimes is ideal. With a callback, one has to implement a registration system for the callbacks if you want multiple.
