C# 7 and .NET: Designing Modern Cross-platform Applications

By: Mark J. Price, Ovais Mehboob Ahmed Khan

Overview of this book

C# is a widely used programming language, thanks to its easy learning curve, versatility, and support for modern paradigms. The language is used to create desktop apps, background services, web apps, and mobile apps. .NET Core is open source and compatible with Mac OS and Linux. There is no limit to what you can achieve with C# and .NET Core. This Learning Path begins with the basics of C# and object-oriented programming (OOP) and explores features of C#, such as tuples, pattern matching, and out variables. You will understand.NET Standard 2.0 class libraries and ASP.NET Core 2.0, and create professional websites, services, and applications. You will become familiar with mobile app development using Xamarin.Forms and learn to develop high-performing applications by writing optimized code with various profiling techniques. By the end of C# 7 and .NET: Designing Modern Cross-platform Applications, you will have all the knowledge required to build modern, cross-platform apps using C# and .NET. This Learning Path includes content from the following Packt products: • C# 7.1 and .NET Core 2.0 - Modern Cross-Platform Development - Third Edition by Mark J. Price • C# 7 and .NET Core 2.0 High Performance by Ovais Mehboob Ahmed Khan

Working with collections


Another of the most common types of data are 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 Standard 2.0 for working with collections are shown in the following table:

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.
