Chapter 7

Interfacing with the Interface

IN THIS CHAPTER

Bullet Going beyond IS_A and HAS_A

Bullet Creating and using interfaces

Bullet Unifying class hierarchies with interfaces

Bullet Managing flexibility via interfaces

A class can contain a reference to another class, which describes the simple HAS_A relationship. One class can extend another class by using inheritance — that's the IS_A relationship. The C# interface implements another, equally important association: the CAN_BE_USED_AS relationship. This chapter introduces C# interfaces and shows some of the numerous ways they increase the power and flexibility of object-oriented programming. Most importantly, you discover how to unify classes with interfaces to produce clearer application code with improved flexibility.
