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.

Storing multiple objects in collections

Another of the most common types of data is collections. If you need to store multiple values in a variable, then you can use a collection.A collection is a data structure in memory that can manage multiple items in different ways, although all collections have some shared functionality.The most common types in .NET for working with collections are shown in Table 8.8:

Namespace Example type(s) Description
System .Collections IEnumerable ,
IEnumerable<T>
Interfaces and base classes used by collections.
System .Collections .Generic List<T> ,
Dictionary<T> ,
Queue<T> ,
Stack<T>
Introduced in C# 2.0 with .NET Framework 2.0. These collections allow you to specify the type you want to store using a generic type parameter (which is safer, faster, and more efficient).
System .Collections .Concurrent BlockingCollection ,
ConcurrentDictionary ,
ConcurrentQueue
These collections are safe to use in multithreaded scenarios...
