Chain of Responsibility to the Rescue!

Chain of Responsibility is one of the less-frequently used design patterns, but also one of the most useful patterns. It helps compose simple decision-making objects into a chain structure, so that the objects get the opportunity to decide in order of their appearance. The first object to successfully complete the task gets all the credits, and its response becomes the result of the entire chain.
That is the theory, and in this video you will learn the practical aspects of applying and implementing the Chain of Responsibility design pattern. We will address the issue of combining simple IComparer instances to build a multi-level sorting comparer object which can be used in contexts where only one IComparer object can be supplied.
