Is there a .NET collection interface that prevents adding objects?

Question

I have a class that maintains list of objects of another class. List of objects is a public property. I would like to prevent users from adding and removing objects directly

Answer 1

Doesn't really answer your question, but is useful information if you decide to implement one of your two ideas: You can use ToArray to create a copy and return an array.
