Why not inherit from List?

Answer 1

Let me rewrite your question. so you might see the subject from a different perspective.

When I need to represent a football team, I understand that it is basically a name. Like: "The Eagles"

string team = new string();

Then later I realized teams also have players.

Why can't I just extend the string type so that it also holds a list of players?

Your point of entry into the problem is arbitrary. Try to think what does a team have (properties), not what it is.

After you do that, you could see if it shares properties with other classes. And think about inheritance.
