C# 12 and .NET 8 – Modern Cross-Platform Development Fundamentals - Eighth Edition

4.6 (14)
By: Mark J. Price

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.

Encoding and decoding text

Text characters can be represented in different ways. For example, the alphabet can be encoded using Morse code into a series of dots and dashes for transmission over a telegraph line.In a similar way, text inside a computer is stored as bits (ones and zeros) representing a code point within a code space. Most code points represent a single character, but they can also have other meanings like formatting.For example, ASCII has a code space with 128 code points. .NET uses a standard called Unicode to encode text internally. Unicode has more than 1 million code points.Sometimes, you will need to move text outside .NET for use by systems that do not use Unicode or a variation of it, so it is important to learn how to convert between encodings.Some common text encodings used by computers are shown in Table 9.6:

Encoding Description
ASCII This encodes a limited range of characters using the lower seven bits of a byte.
UTF-8 This represents each Unicode code...
