Is it possible to declare a delegate in one class (methods in the same place), and create a variable, assign the address of a method, call it in another class?

Question

C++ / C#

Is it possible to declare a delegate in one class (methods in the same place), and create a variable, assign the address of a method, call it in another class?
The situation is as follows:
There is a namespace and two classes, in the second lane. All methods are in the first class. And I want to declare a delegate, etc. there, but use it in another class, but somehow it doesn’t work, all the examples that I saw within the same class ... :-(

Answer 1

There is such a thing as "scope". If the delegate type is inside a class, then it can only be obtained through an instance of this class, i.e. through an object of the type of that class. To be able to create a delegate in another class, you must either remove the delegate from it, or, as I said, refer to an instance of the class.

Answer 2

And who's stopping you from doing this?.. A delegate can be declared not in a class at all, but simply in a namespace. After all, a delegate is just a method signature (number and types of method arguments).
