.NET 4.0 Generics Beginner's Guide

Lists under the hood

So far in this chapter, we have learnt about many generic containers. This is the perfect time to know how they fit in to the entire ecosystem of .NET Generics. Different list-based implementations implement different interfaces. These relationships are shown as follows:

Generic collection	Interfaces it implements	What's the significance?
Stack<T>	IEnumerable<T> ICollection IEnumerable	Stack is a generic collection that has to be enumerable. It is also a collection, so any collection can be converted to Stack. For that ICollection is implemented.
Queue<T>	IEnumerable<T> ICollection IEnumerable	From compiler's standpoint Stack and Queue are identical. Only their concrete implementation for these interface ...
