What is a Collection<T> class in C# and how does it differ from other collections?

• Collection<T> is a base class for creating custom collections.
• It wraps an IList<T> internally and provides virtual methods for insert, remove, and

clear, allowing easy customization.

• Unlike List<T>, which is optimized for performance, Collection<T> focuses on

extensibility.

• Useful when you want to create a collection with customized behaviors (e.g.,

validation, event firing).
