Polymorphism, Up-casting and Down-casting

Polymorphism, Up-casting and Down-casting
By Phil Curnow June 25, 2007

This article gives an introduction to polymorphism in C#. Using the example created in this introduction, the article then goes on to describe how we up-cast and down-cast objects.

This is a good article about Polymorphism. I can say this is a thumbs up and a little bit simple and nice code!
