C# Programming Cookbook

Overview of this book

During your application development workflow, there is always a moment when you need to get out of a tight spot. Through a recipe-based approach, this book will help you overcome common programming problems and get your applications ready to face the modern world. We start with C# 6, giving you hands-on experience with the new language features. Next, we work through the tasks that you perform on a daily basis such as working with strings, generics, and lots more. Gradually, we move on to more advanced topics such as the concept of object-oriented programming, asynchronous programming, reactive extensions, and code contracts. You will learn responsive high performance programming in C# and how to create applications with Azure. Next, we will review the choices available when choosing a source control solution. At the end of the book, we will show you how to create secure and robust code, and will help you ramp up your skills when using the new version of C# 6 and Visual Studio

Creating and implementing an interface


For many developers, interfaces are confusing and their purpose not clearly understood. Interfaces are actually quite easy to get to grips with once you understand the concept that defines an interface.

Interfaces act like verbs. So, for example, if we had to create two classes called Lion and Tiger that derive from the Cat abstract class, the interface would describe some sort of action. Lions and tigers can roar (but not purr). We can then create an interface called IRoarable. If we had to derive a class called Cheetah from our abstract class Cat, we would not be able to use the IRoarable interface, because cheetahs purr. We would need to create an IPurrable interface.

Getting ready

Creating an interface is very similar to creating an abstract class. The difference is that the interface is describing what the class can do, in the case of the Cheetah class, by implementing IPurrable.
