Pro LINQ: Language Integrated Query in C# 2010

Overview

LINQ is the part of the .NET Framework that provides a generic approach to querying data from different data sources. It has quickly become the next must-have skill for .NET developers. Pro LINQ: Language Integrated Query in C# 2010 is all about code. Literally, this book starts with code and ends with code. Most books show the simplest examples of how to use a method, but they so rarely show how to use the more complex prototypes. This book is different. Demonstrating the overwhelming majority of LINQ operators and prototypes, it is a veritable treasury of LINQ examples.

Rather than obscure the relevant LINQ principles in code examples by focusing on a demonstration application you have no interest in writing, this book cuts right to the chase of each LINQ operator, method, or class. However, where complexity is necessary to truly demonstrate an issue, the examples are right there in the thick of it. For example, code samples demonstrating how to handle concurrency conflicts actually create concurrency conflicts so you can step through the code and see them unfold.

Face it, most technical books, while informative, are dull. LINQ need not be dull. Written with a sense of humor, this book will attempt to entertain you on your journey through the wonderland of LINQ and C# 2010.

What you’ll learn

• How to leverage all the new LINQ relevant C# 2008 language features including extension methods, lambda expressions, anonymous data types, and partial methods.
• How to use LINQ to Objects to query in-memory data collections such as arrays, ArrayLists, and Lists to retrieve the data you want.
• Why some queries are deferred, how a deferred query can bite you, and how you can make deferred queries work for you.
• How to use LINQ to XML to revolutionize your creation, manipulation, and searching of XML data.
• How to query DataSets with LINQ to DataSet so you can coexist with legacy code and use LINQ to query databases other than SQL Server.
• How to query Databases with LINQ to SQL, write your own entity classes, and understand how to handle concurrency conflicts.

This book is written for the proficient C# developer, but you do not need to be up on all the latest C# features to understand the material. When you finish this book, you will have a much greater understanding of the latest C# features.
