Welcome to Starting Out with Visual C#, Fifth Edition. This book is intended for an introductory programming course and is ideal for students with no prior experience. Students who are new to programming will appreciate the clear, down-to-earth explanations and the detailed walk-throughs that are provided by the hands-on tutorials. More experienced students will appreciate the depth of detail as they learn about the .NET Framework, databases, Language-Integrated Query, and other topics.

As with all the books in the Starting Out With series, the hallmark of this text is its clear, friendly, and easy-to-understand writing. In addition, it is rich in example programs that are concise and practical. The programs in this book include short examples that highlight specific programming topics, as well as more involved examples that focus on problem solving. Each chapter provides numerous hands-on tutorials that guide the student through each step of the development of an application. In addition to detailed, step-by-step instructions, the tutorials also provide the applications completed code and screen captures of the completed forms.

The biggest changes in this edition appear in the last half of the book. Some of the chapters have been reorganized, and two new chapters have been added. Here is a summary of the reorganization:

• The ImageList control is now covered along with Arrays and Lists in . Since an ImageList is a collection of images, it is fitting that this control be covered in the same chapter as Arrays and Lists.

• is titled Structures, Enumerated Types, and Dictionaries.

• Two new chapters have been added. In this edition, is titled Language-Integrated Query (LINQ).

An abundance of new topics and improvements has been added to this edition:

• var Keyword: This edition introduces the var keyword for variable declaration.

• Advanced String Formatting: includes a new section on formatting strings with the String.Format method.

• Working with Dates and Times: includes a new section about working with dates and times. The section covers the DateTime and TimeSpan data types, as well as the DateTimePicker control.

• Dictionaries: includes a new section on the Dictionary collection. The student learns to store and work with data as keyvalue pairs in dictionaries.

• More Use of Auto-Properties: In the previous editions, property declarations were almost always written with explicitly declared backing fields, even when the properties were simply used to set and get a value. Where possible, those property declarations have been rewritten as auto-properties.

• Object Initializer Syntax: Object initializer syntax is introduced in as an alternative way to declare and initialize structures and class instances.

• Static Members: has a new section on static fields, properties, methods, and classes.

• Sealed Classes and Methods: has a new discussion on using the sealed keyword to prevent classes from being inherited from, and to prevent methods from being overridden.

• Extension Methods: covers extension methods, which allow you to extend classes that you cannot inherit from, as well as the primitive data types.

• Interfaces: now includes a section on writing and using interfaces.

• Delegates: introduces the student to delegates.

• Anonymous Methods: also introduces anonymous methods, which go hand-in-hand with delegates.

• Lambda Expressions: concludes by showing the student how to use a lambda expression to concisely create a delegate and anonymous method.

• Language-Integrated Query (LINQ): introduces LINQ, and shows how to query simple data structures such as arrays and Lists using LINQ to Objects , and how to query databases using LINQ to SQL .
