Overview of this book

Traditionally associated with Windows desktop applications and game development, C# has expanded into web, cloud, and mobile development. However, despite its extensive coding features, professionals often encounter issues with efficiency, scalability, and maintainability due to poor code. Clean Code in C# guides you in identifying and resolving these problems using coding best practices. This book starts by comparing good and bad code to emphasize the importance of coding standards, principles, and methodologies. It then covers code reviews, unit testing, and test-driven development, and addresses cross-cutting concerns. As you advance through the chapters, you’ll discover programming best practices for objects, data structures, exception handling, and other aspects of writing C# computer programs. You’ll also explore API design and code quality enhancement tools, while studying examples of poor coding practices to understand what to avoid. By the end of this clean code book, you’ll have the developed the skills needed to apply industry-approved coding practices to write clean, readable, extendable, and maintainable C# code.

Higher-order functions

In C#, a higher-order function is a function that takes one or more functions as arguments or returns a function as its result. This concept is an essential aspect of functional programming and enables powerful abstractions and code reusability.

There are two main types of higher-order functions in C#:

  • Functions that take other functions as arguments: These higher-order functions accept one or more functions as parameters. They can then apply those functions to data or invoke them within their own implementation. By passing different functions as arguments, the higher-order function can be customized to perform various operations without needing separate implementations for each case.

    In functional programming, one of the key principles is immutability. In C#, you can use LINQ to achieve a non-mutating state. Here’s an example of a higher-order function that takes functions as arguments and uses LINQ without violating the non-mutating state concept...
