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

Chapter 9. Regular Expressions

Regular Expressions (regex) are somewhat of a mystery for many developers. We admit that they are something that we use often enough to warrant a deeper understanding of how they work. On the flip side, there are so many tried and tested regex patterns on the Internet that just reusing one that already exists is most times easier than trying to create one yourself. The subject of regex is much larger than what can be explained in a single chapter in this book.

Therefore, in this chapter, we will merely introduce some of the concepts of regex. For a deeper understanding of regex, further study is needed. For the purpose of this book, however, we will take a closer look at how regex are created and how they can be applied to some common programming problems. In this chapter, we will cover the following recipes:

  • Getting started with regex

  • Matching a valid date

  • Sanitizing input

  • Dynamic regex matching
