Working with Interfaces

  • Andrew Troelsen


This chapter builds upon your current understanding of object-oriented development by examining the topic of interface-based programming. Here you’ll learn how to define and implement interfaces, and come to understand the benefits of building types that support multiple behaviors. Along the way, I’ll also discuss a number of related topics, such as obtaining interface references, explicit interface implementation, and the construction of interface hierarchies. We’ll also examine a number of standard interfaces defined within the .NET base class libraries. As you will see, your custom classes and structures are free to implement these predefined interfaces to support a number of useful behaviors, such as object cloning, object enumeration, and object sorting.
