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

Choosing the right data structure for performance optimization

A data structure is a precise way of organizing data in a computer program. If data is not efficiently stored in the right data structure, it may lead to some performance issues that impact the overall experience of the application.

In this section, we will learn the advantages and disadvantages of the different collection types available in .NET Core and which ones are the better types for particular scenarios:

  • Arrays and lists
  • Stacks and queues
  • LinkedLists (single, double, and circular)
  • Dictionaries, hashtables, and hashsets
  • Generic lists

Arrays

An array is a collection that holds similar types of elements. Arrays of both value types and reference types can be created.

Here are few circumstances where arrays are useful:

  • If the data is of a fixed, set length, using an array is a better option as it is faster than other collections, such as arraylists and generic lists
  • Arrays are good to represent data in a multidimensional way
  • They take...
