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.

Checking for overflow

Earlier, we saw that when casting between number types, it was possible to lose information, for example, when casting from a long variable to an int variable. If the value stored in a type is too big, it will overflow.

Throwing overflow exceptions with the checked statement

The checked statement tells .NET to throw an exception when an overflow happens instead of allowing it to happen silently, which is done by default for performance reasons.We will set the initial value of an int variable to its maximum value minus one. Then, we will increment it several times, outputting its value each time. Once it gets above its maximum value, it overflows to its minimum value and continues incrementing from there.Let's see this in action:

  1. In Program.cs, type statements to declare and assign an integer to one less than its maximum possible value, and then increment it and write its value to the console three...
