Functional Programming with C#

By: Alex Yagur

Overview of this book

In an era where software complexity is increasing by the day, functional programming offers a paradigm that simplifies code maintenance and enhances reliability. Functional Programming with C# takes you on an exhaustive journey into functional programming within C#. The book familiarizes you with the core principles and benefits of functional programming, juxtaposing it with imperative and object-oriented paradigms. You’ll get to grips with the functional features of C# and learn to write expressive, modular code through expressions, pure functions, and higher-order functions. As you advance, you’ll explore advanced concepts such as error handling and asynchronous programming, which will equip you with the practical skills that you need to tackle real-world challenges. By comparing functional programming in C# with other languages and providing additional resources, this book ensures that you’re well-equipped to continue your journey toward mastery in functional programming. By the end of this book, you’ll have gained a thorough understanding of functional programming techniques, such as recursion, memoization, and composition, empowering you to write robust, maintainable code.

Honest Functions, Null, and Option

In this chapter, we discuss the art and science of honest functions, the intricacies of null, and the C# tools tailored to address them. But before we dive deep, let’s lay out the roadmap:

  • Understanding honest functions
  • The problems with hidden nulls
  • Embracing honesty with nullable reference types
  • Beyond null: Option
  • Real-world scenarios

As you navigate through this chapter, be on the lookout for practical advice and evidence-backed guidelines. Come with a curious mind, and by the end, you’ll possess the know-how to write more transparent and resilient C# code.

Just as we did in our previous chapters, let’s assess where you stand. Here, there are three tasks for you. If you’re unsure about tackling them, dive into this chapter right away. But, if you feel confident in your skills, perhaps you might skim through and jump to the sections that challenge you the most. Ready? Let’s go...
