By: Tom Owsiak

Overview of this book

Beginning C# 7 Hands-On – Advanced Language Features assumes that you’ve mastered the basic elements of the C# language and that you're now ready to learn the more advanced C# language and syntax, line by line, in a working Visual Studio environment. You'll learn how to code advanced C# language topics including generics, lambda expressions, and anonymous methods. You'll learn to use query syntax to construct queries and deploy queries that perform aggregation functions. Work with C# and SQL Server 2017 to perform complex joins and stored procedures. Explore advanced file access methods, and see how to serialize and deserialize objects – all by writing working lines of code that you can run within Visual Studio. This book is designed for beginner C# developers who have mastered the basics now, and anyone who needs a fast reference to using advanced C# language features in practical coding examples. You'll also take a look at C# through web programming with web forms. By the time you’ve finished this book, you’ll know all the critical advanced elements of the C# language and how to program everything from C# generics to XML, LINQ, and your first full MVC web applications. These are the advanced building blocks that you can then combine to exploit the full power of the C# programming language, line by line.

Preface

Creating a button to exchange and then comparing two values


Open up a project and click on the <html> tab. The only thing to put in there is a button. This time, we will not read any values from the user just to save time. So, go to Toolbox and grab a Button control. Drag and drop it below the line beginning with <form id=... (you can delete the <div> lines, as we won't be needing them). Change the text on the button to say Exchange And Compare. So, this will exchange two values and then compare them. Your complete Default.aspx file should look like the one shown in Figure 2.2.1:
