Overview of this book

This latest edition of the bestselling Packt series will give you a solid foundation to start building projects using modern C# and .NET with confidence. You'll learn about object-oriented programming; writing, testing, and debugging functions; and implementing interfaces. You'll take on .NET APIs for managing and querying data, working with the fi lesystem, and serialization. As you progress, you'll explore examples of cross-platform projects you can build and deploy, such as websites and services using ASP.NET Core. This latest edition integrates .NET 8 enhancements into its examples: type aliasing and primary constructors for concise and expressive code. You'll handle errors robustly through the new built-in guard clauses and explore a simplified implementation of caching in ASP.NET Core 8. If that's not enough, you'll also see how native ahead-of-time (AOT) compiler publish lets web services reduce memory use and run faster. You'll work with the seamless new HTTP editor in Visual Studio 2022 to enhance the testing and debugging process. You'll even get introduced to Blazor Full Stack with its new unified hosting model for unparalleled web development flexibility.

Sorting and more

Other commonly used extension methods are OrderBy and ThenBy, used for sorting a sequence.

Sorting by a single property using OrderBy

Extension methods can be chained if the previous method returns another sequence, that is, a type that implements the IEnumerable<T> interface.Let's continue working with the current project to explore sorting:

  1. In the FilteringUsingWhere method, append a call to OrderBy to the end of the existing query, as shown in the following code:
var query = names
  .Where(name => name.Length > 4)
  .OrderBy(name => name.Length);

Good Practice: Format the LINQ statement so that each extension method call happens on its own line, to make it easier to read.

  1. Run the code and note that the names are now sorted by shortest first, as shown in the following output:

To put the longest name first, you would use OrderByDescending.

Sorting by a subsequent property using ThenBy
