Overview of this book

Functional programming makes your application faster, improves performance, and increases your productivity. C# code is written at a higher level of abstraction, so that code will be closer to business requirements, abstracting away many low-level implementation details. This book bridges the language gap for C# developers by showing you how to create and consume functional constructs in C#. We also bridge the domain gap by showing how functional constructs can be applied in business scenarios. We’ll take you through lambda expressions and extension methods, and help you develop a deep understanding of the concepts and practices of LINQ and recursion in C#. By the end of the book, you will be able to write code using the best approach and will be able to perform unit testing in functional programming, changing how you write your applications and revolutionizing your projects.

Chapter 3. Expressing Anonymous Methods with Lambda Expressions

We covered delegates in the previous chapter, as it was a pre-requisite for understanding anonymous methods and lambda expressions, the subject of the current chapter. By using an anonymous method, we can create a delegate instance with no need to have a separate method. By using the lambda expression, we can create a shorthand syntax for the anonymous method. In this chapter, we are going to dig up the anonymous methods as well as Lambda expressions. The topics in this chapter are as follows:

  • Applying delegate to create and use anonymous methods
  • Transformation of anonymous methods to lambda expressions
  • Understanding expression trees and its relation to lambda
  • Subscribing for events using lambda expressions
  • Elaborating the benefit of lambda expressions in the use of functional programming
