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

The object in question will need to implement an interface provided by you. Take the interface as a parameter, and then you can call any method that the interface exposes. Otherwise you have no way of knowing what the object is capable of. That, or you could take a delegate as a parameter and call that.
