What design pattern to choose for a list of objects of different types?

Question

C++ / C#

There are three types of objects: 1
) A slot that displays information
2) A free slot
3) A locked slot
this type? I write in C#. So far, only a solution with a type check is spinning in my head. Maybe there is some design pattern that allows you to solve this problem?

Answer 1

Implement the same interface for all three types of objects, no patterns

Answer 2

As I understand it, you need pattern matching, I'm not strong in C # (the last time I used it was in 2010)

Answer 3

Here are the options:
1. Inheritance from one class
2. Implementation of one interface.
3. A special wrapper class that can take elements of your zoo as input and convert them into a standard interface to the collection.
And I don't really understand why you don't like typecasting to access unique fields. This is absolutely standard practice.
