Overview of this book

C# is a powerful, versatile language that can unlock a variety of career paths. But, as with any programming language, learning C# can be a challenging process. With a wide range of different resources available, it’s difficult to know where to start. That's where The C# Workshop comes in. Written and reviewed by industry experts, it provides a fast-paced, supportive learning experience that will quickly get you writing C# code and building applications. Unlike other software development books that focus on dry, technical explanations of the underlying theory, this Workshop cuts through the noise and uses engaging examples to help you understand how each concept is applied in the real world. As you work through the book, you'll tackle realistic exercises that simulate the type of problems that software developers work on every day. These mini-projects include building a random-number guessing game, using the publisher-subscriber model to design a web file downloader, creating a to-do list using Razor Pages, generating images from the Fibonacci sequence using async/await tasks, and developing a temperature unit conversion app which you will then deploy to a production server. By the end of this book, you'll have the knowledge, skills, and confidence to advance your career and tackle your own ambitious projects with C#.

Introduction

Throughout the previous chapters, you have used variables that refer to a single value, such as the string and double system types, system class instances, and your own class instances. .NET has a variety of data structures that can be used to store multiple values. These structures are generally referred to as collections. This chapter builds on this concept by introducing collection types from the System.Collections.Generic namespace.

You can create variables that can store multiple object references using collection types. Such collections include lists that resize to accommodate the number of elements and dictionaries that offer access to the elements using a unique key as an identifier. For example, you may need to store a list of international dialing codes using the codes as unique identifiers. In this case, you need to be certain that the same dialing code is not added to the collection twice.

These collections are instantiated like any other classes and...
