Learn C# language basics, including variables, arrays, logic, looping, methods, and classes, and then move on to Object Oriented Programming – all in easy steps! Modern coding with C# 10 and .NET 6. Updated for Visual Studio 2022

C# Programming in easy steps, 3rd edition teaches you how to code applications and demonstrates every aspect of the C# language you will need to produce professional programming results. Its examples provide clear syntax-highlighted code showing C# language basics including variables, arrays, logic, looping, methods, and classes.

The book begins by explaining how to install the free Visual Studio Community Edition, to create an environment in which you can quickly begin to create your own executable programs by copying the book's examples. It demonstrates all the C# language basics before moving on to provide examples of Object Oriented Programming. It concludes by demonstrating how you can use your acquired knowledge to create graphic programs for traditional PC Desktop apps, and also as Universal apps for multiple devices.

You need have no previous knowledge of any programming language, so it's ideal for the newcomer to computer programming.

Also ideal for:

Programmers moving from another programming language.

Students who are studying C# programming at school or college.

Those seeking a career in computing who need a fundamental understanding of procedural programming.

Free, downloadable sample code is available to download from our website for checking against your own work.

Summary

Introducing C#

The introduction of the Microsoft .NET framework at the Professional Developers Conference in July 2000 also saw Microsoft introduce a new programming language called C# (pronounced “see-sharp”). The name was inspired by musical notation where a # sharp symbol indicates that a written note should be a semitone higher in pitch. This notion is similar to the naming of the C++ programming language where the ++ symbol indicates that a written value should be incremented by 1.

•C# is designed to be a simple, modern, general-purpose, object-oriented programming language, borrowing key concepts from several other languages – most notably the Java programming language. Consequently, everything in C# is a class “object” with “properties” and “methods” that can be employed by a program.

•C# is an elegant and “type-safe” programming language that enables developers to build a variety of secure and robust applications. You can use C# to create Windows client applications, XML web services, distributed components, client-server applications, database applications, and much, much more.

•C# is specifically designed to utilize the proven functionality built into the .NET framework “class libraries”. Windows applications written in C# therefore require the Microsoft .NET framework to be installed on the computer running the application – typically, an integral component of the system.

The Microsoft .NET Framework

Each version of the Microsoft .NET framework includes a unified set of class libraries and a virtual execution system called the Common Language Runtime (CLR). The CLR allows the C# language and the class libraries to work together seamlessly.

To create an executable program, source code written in the C# language is compiled by the C# Compiler into Intermediate Language (IL) code. This is stored on disk, together with other program resources such as images, in an “assembly”. Typically, the assembly will have a file extension of .ex...
