Why are delegates similar to interfaces ?

Question

On my way to explore delegates some more.
I have looked this video today from kudenvat.

Delegates are a variable type that point to a method
Interface are method definitions without a body

So why are they similar ?

Answer 1

A delegate is like an interface that the function must conform to, just like a class/struct must conform to it's interfaces? It abstracts away the function being called, just like an interface abstracts away the object behind it?

Answer 2

Thanks. I think you are right.

Was reading this article : http://csharpindepth.com/articles/chapter2/events.aspx

The article it self it pretty difficult but this sentence clarified things for me.

"In some ways, you can think of a delegate type as being a bit like an interface with a single method. "
