Why BindingList<T> RemoveItem method is protected

Question

Tell me please, why BindingList RemoveItem method is protected? What is the purpose of it? I know I can just inherit from it but the question is why one have made this protected

Answer 1

This is protected because BindingList<T> is based on Collection<T>, and RemoveItem is intended for implementations of Collection<T> to provide the proper, collection-specific implementation.

To use this directly, you can use the public RemoveAt method. This calls RemoveItem internally, but is the public-facing API for removing an item by index.
