Welcome to the Visual C#® 2010 programming language and the world of Microsoft® Windows® and Internet programming with Microsoft’s .NET platform!
This book focuses on software engineering best practices. At the heart of the book is the Deitel signature “live-code approach.” Concepts are presented in the context of working programs, rather than in code snippets. Each code example is accompanied by sample executions. All the source code is available at www.deitel.com/books/vcsharp2010htp/ and at the book’s Companion Website at www.pearsonhighered.com/deitel/.
As you read the book, if you have questions, send an e-mail to [email protected]; we’ll respond promptly.

Here are the updates we’ve made for Visual C#® 2010 How to Program, 4/e:
Printed book contains core content; advanced chapters are online. The printed book contains sufficient core content for most introductory Visual C# course sequences. Several online chapters are included for more advanced courses and for professionals. These are available in searchable PDF format on the book’s password-protected Companion Website—see the access card in the front of this book.
The book’s Companion Website includes extensive VideoNotes in which coauthor Paul Deitel explains in detail most of the programs in the core chapters.
Making a Difference exercises set. We encourage you to use computers and the Internet to research and solve significant social problems. These new exercises are meant to increase awareness and discussion of important issues the world is facing. We hope you’ll approach them with your own values, politics and beliefs.
Up-to-date with Visual C# 2010, C# 4, the Visual Studio 2010 IDE and .NET 4. The C# language has been standardized internationally by ECMA and ISO. The latest version of that language is referred to as C# 4. Microsoft’s implementation of this standard is referred to as Visual C# 2010.
New language features. We cover new C# features, such as optional parameters, named parameters, covariance and contravariance.
Databases. We use Microsoft’s free SQL Server Express (which installs with the free Visual C# Express) to teach the fundamentals of database programming. Chapters 18, 19, 27 and 28 use database and LINQ fundamentals in the context of an address-book desktop application, a web-based guestbook, a bookstore and an airline reservation system.
ASP.NET 4. Microsoft’s .NET server-side technology, ASP.NET, enables you to create robust, scalable web-based applications. In Chapter 19, you’ll build several applications, including a web-based guestbook application that uses ASP.NET, LINQ and a
LinqDataSourceto store data in a database and display data in a web page. The chapter also discusses the ASP.NET Development Server for testing your web applications on your local computer.We removed generic methods from Chapter 9 to make the code easier to understand.
The code will run on Windows 7, Windows Vista and Windows XP. We’ll post any issues on www.deitel.com/books/vcsharp2010htp/.
We introduce exception handling much earlier (Chapter 8) and integrated it in subsequent chapters in which it had not been used previously. We also now throw exceptions for invalid data received in the
setaccessors of properties.New design. The book has a new interior design that graphically organizes, clarifies and highlights the information, and enhances the book’s pedagogy. We used italics extensively to emphasize important words, phrases and points in the text.
We titled the programming exercises to help instructors tailor assignments.
Other features of Visual C# 2010 How to Program, 4/e include:
We’ve provide instructors with solutions to the vast majority of the exercises. There are a few large exercises marked “Project” for which solutions are not provided.
We use LINQ (Language Integrated Query) to query files, databases, XML and collections. The introductory LINQ chapter, Chapter 9, in the core printed book is intentionally brief to encourage instructors to cover this important technology early. The online chapters continue the discussion of LINQ.
Local type inference. When you initialize a local variable in its declaration, you can now omit the variable’s type—the compiler infers it from the initializer value.
Object initializers. For new objects, you can use object initializer syntax (similar to array initializer syntax) to assign values to the new object’s
publicproperties andpublicinstance variables.We emphasize the IDE’s IntelliSense feature that helps you write code faster and with fewer errors.
We surveyed hundreds of instructors teaching Visual C# courses and learned that most want a book with content focused on their introductory courses. With that in mind, we moved various intermediate and advanced chapters to the web. Having this content in digital format makes it easily searchable, and gives us the ability to fix errata and add new content as appropriate. The book’s Companion Website at
www.pearsonhighered.com/deitel/ |
(see the access card at the front of the book) contains the following chapters in searchable PDF format:
WPF (Windows Presentation Foundation) GUI, graphics and multimedia. We extend the core book’s GUI coverage in Chapters 24–25 with an introduction to Windows Presentation Foundation (WPF)—Microsoft’s new framework that integrates GUI, graphics and multimedia capabilities. We implement a painting application, a text editor, a color chooser, a book-cover viewer, a television video player, various animations, and speech synthesis and recognition applications.
ASP.NET 4 and ASP.NET AJAX. Chapter 27 extends Chapter 19’s ASP.NET discussion with a case study on building a password-protected, web-based bookstore application. We also introduce ASP.NET AJAX controls and use them to add AJAX functionality to web applications to improve their responsiveness.
WCF (Windows Communication Foundation) Web Services. Web services enable you to package application functionality in a manner that turns the web into a library of reusable services. In Chapter 28, we include case studies on building an airline reservation web service, a blackjack web service and a math question generator web service that’s called by a math tutor application.
Silverlight. Chapter 29 introduces Silverlight, which enables you to create visually stunning, multimedia-intensive user interfaces for web applications. The chapter presents powerful multimedia applications, including a weather viewer, Flickr photo viewer, deep zoom book-cover collage and video viewer.
Visual C# XML capabilities. Use of the Extensible Markup Language (XML) is exploding in the software-development industry and in e-business, and is pervasive throughout the .NET platform. In Chapter 26, we use show how to programmatically manipulate the elements of an XML document using LINQ to XML.
Optional Case Study: Using the UML to Develop an Object-Oriented Design and C# Implementation of an ATM. The UML™ (Unified Modeling Language™) is the preferred graphical modeling language for designing object-oriented systems. This edition includes an optional online case study on object-oriented design using the UML (Chapters 30–31). We design and implement the software for a simple automated teller machine (ATM). We analyze a typical requirements document that specifies the system to be built. We determine the classes needed to implement that system, the attributes the classes need to have, the behaviors the classes need to exhibit and specify how the classes must interact with one another to meet the system requirements. From the design we produce a working Visual C# implementation. We’ve presented this case study to professional audiences in C#, Java, Visual Basic and C++. After seeing the case-study presentation, students report having a “light-bulb moment”—the case study “ties it all together” for them and helps them understand how objects in a larger system communicate with one another.
Index. The online index includes the content from the printed book and the online content. The printed book index covers only the printed material.
The charts in Figs. 1-2 show the dependencies among the chapters to help instructors plan their syllabi. The printed book focuses on introductory course sequences (Fig. 1). The online chapters include intermediate and advanced content for more advanced courses (Fig. 2).
Visual C# 2010 How to Program, 4/e contains a rich collection of examples. We concentrate on building good software and stress program clarity.
Live-Code Approach. The book is loaded with “live-code” examples. Most new concepts are presented in the context of complete working Visual C# applications, followed by one or more executions showing program inputs and outputs. In the few cases where we use snippets, we tested them in complete working programs then copied the code from the program and pasted it into the book.
Syntax Shading. For readability, we syntax shade the code, similar to the way most integrated-development environments and code editors syntax color the code. Our syntaxshading conventions are:
comments appear like this keywords appear like this constants and literal values appear like this all other code appears in black |
Code Highlighting. We place gray rectangles around each program’s key code.
Using Fonts for Emphasis. We place the key terms and the index’s page reference for each defining occurrence in bold text for easy reference. We emphasize on-screen components in the bold Helvetica font (for example, the File menu) and Visual C# program text in the Lucida font (for example, int count = 5).
Objectives. The opening quotes are followed by a list of chapter objectives.
Illustrations/Figures. Abundant tables, line drawings, UML diagrams, programs and program outputs are included.
Programming Tips. We include programming tips to help you focus on important aspects of program development. These tips and practices represent the best we’ve gleaned from a combined seven decades of programming and teaching experience.
Good Programming Practice
The Good Programming Practices call attention to techniques that will help you produce programs that are clearer, more understandable and more maintainable.
