Clean Code in C#

By: Jason Alls

Overview of this book

Traditionally associated with developing Windows desktop applications and games, C# is now used in a wide variety of domains, such as web and cloud apps, and has become increasingly popular for mobile development. Despite its extensive coding features, professionals experience problems related to efficiency, scalability, and maintainability because of bad code. Clean Code in C# will help you identify these problems and solve them using coding best practices. The book starts with a comparison of good and bad code, helping you understand the importance of coding standards, principles, and methodologies. You’ll then get to grips with code reviews and their role in improving your code while ensuring that you adhere to industry-recognized coding standards. This C# book covers unit testing, delves into test-driven development, and addresses cross-cutting concerns. You’ll explore good programming practices for objects, data structures, exception handling, and other aspects of writing C# computer programs. Once you’ve studied API design and discovered tools for improving code quality, you’ll look at examples of bad code and understand which coding practices you should avoid. By the end of this clean code book, you’ll have the developed skills you need in order to apply industry-approved coding practices to write clean, readable, extendable, and maintainable C# code.

Knowing when to send code for review

Code reviews should take place when the development is complete and before the programmer of the code passes the code on to the QA department. Before any code is checked into version control, all the code should build and run without errors, warnings, or information. You can ensure this by doing the following:

  • You should run static code analysis on your programs to see whether any issues are raised. If you receive any errors, warnings, or information, then address each point raised. Do not ignore them as they can cause problems further down the line. You can access the Code Analysis configuration dialog on the Code Analysis page of the Visual Studio 2019 Project Properties tab. Right-click on your project and select Properties | Code Analysis.
  • You should also make sure that all your tests run successfully, and you should aim to have all your new code to be fully covered by normal and exceptional use cases that test...
