How delegates work (in the background)?

Question

How do delegates work in c# behind the scenes and how can they be used efficiently?

EDIT: I know how they work on the surface(they are basically function pointers a

Answer 1

Delegates in C# are lists of method pointers. I.e. they store references to code, and you can invoke the methods via the pointers. This is useful in many cases. The common example is for event handlers where delegates are used to implement a publisher/subscriber pattern.
