Generics Sample (C#)

This sample shows how to create a custom generic list class that has a single type parameter, and how to implement IEnumerable<T> to enable foreach iteration over the contents of the list. The sample also shows how client code creates an instance of the class by specifying a type argument, and how constraints on the type parameter enable additional operations to be performed on the type arguments.

For an example of a generic collection class that implements an iterator block, see How to: Create an Iterator Block for a Generic List (C# Programming Guide).
