Callbacks in C#

Question

I want to have a library that will have a function in it that accepts an object for it\'s parameter.

With this object I want to be able to call a specified function

Answer 1

Is there a reason not to have your library provide a public event to be fired when the operation is complete? Then the caller could just register to handle the event and you don't have to worry about passing around objects or delegates.

The object implementing an interface you have provided would work, but it seems to be more the Java approach than the .NET approach. Events seem a bit cleaner to me.
