Overview of this book

The C# programming language is often developers’ primary choice for creating a wide range of applications for desktop, cloud, and mobile. In nearly two decades of its existence, C# has evolved from a general-purpose, object-oriented language to a multi-paradigm language with impressive features. This book will take you through C# from the ground up in a step-by-step manner. You'll start with the building blocks of C#, which include basic data types, variables, strings, arrays, operators, control statements, and loops. Once comfortable with the basics, you'll then progress to learning object-oriented programming concepts such as classes and structures, objects, interfaces, and abstraction. Generics, functional programming, dynamic, and asynchronous programming are covered in detail. This book also takes you through regular expressions, reflection, memory management, pattern matching, exceptions, and many other advanced topics. As you advance, you'll explore the .NET Core 3 framework and learn how to use the dotnet command-line interface (CLI), consume NuGet packages, develop for Linux, and migrate apps built with .NET Framework. Finally, you'll understand how to run unit tests with the Microsoft unit testing frameworks available in Visual Studio. By the end of this book, you’ll be well-versed with the essentials of the C# language and be ready to start creating apps with it.

Chapter 13: Files, Streams, and Serialization

Programming is all about processing data that could come from various sources, such as local memory, disk files, or from a remote server over the network. Most data has to be persisted for either a long time or indefinitely. It has to be available between different application restarts or shared between multiple applications. Whether the storage is plain text files or various types of databases, whether they are local, from the network, or a cloud, whether the physical location is hard disk drives, solid state drives, or USB sticks, all data is preserved in a filesystem. Different platforms have different types of filesystems, but they all work with the same abstractions: paths, files, and directories.

In this chapter, we look at the functionalities that .NET provides for working with filesystems. The main topics that will be covered in this chapter are as follows:

  • Overview of the System.IO namespace
  • Working with paths
  • ...
