How is the data type for delegates represented in the programming language?

In C#, delegates are represented as types that encapsulate references to methods with a specific signature and return type. A delegate is an object that can be invoked like a method, and it will call all the methods it references.

The declaration of a delegate looks like this:

public delegate int MyDelegate(string s);

Here, MyDelegate is a delegate type that references methods accepting a string and returning an int.

Delegates are type-safe and support multicast (multiple methods in the invocation list). They are often used for events and callbacks.
