A delegate in C# is similar to a function pointer in C.

And using a delegate allows a programmer to encapsulate a reference to a method inside a delegate.

The delegate object can then be passed to code which can call the reference without knowing without having to know at compile time which method will be known.

A very interesting property of a delegate is that it does not care about the object of the class. That it references. All matters is that methods argument type and
object return type match the delegates.
