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

Adding a Show Results button to the HTML


Open up a project and, inside the <html>, put in a single button that says Show Results. For this, go to the Toolbox and grab a Button control. Drag and drop it below the line beginning with <form id=.... You can delete the <div> lines, as you don't need them. Be sure to insert a <br> tag at the end of the Button line.

<asp:Button ID="Button1" runat="server" Text="Show Results" /><br />

Next, we will display some results to the user. To do this, go to the Design view, and double-click on the Show Results button. This takes us into Default.aspx.cs. Delete the Page_Load block. The relevant portion of the starting code for this project should look like Figure 8.3.1:
