LINQ, Language INtegrated Query, is a new extension to the Visual Basic and C#
programming languages designed to simplify data queries and database
interaction. It addreses O/R mapping issues by making query operations like
SQL statements part of the programming language. It also offers built-in
support for querying in-memory collections like arrays or lists, XML,
DataSets, and relational databases.
LINQ in Action
is a fast-paced, comprehensive tutorial for professional developers. This book
explores what can be done with LINQ, shows how it works in an application, and
addresses the emerging best practices. It presents the general purpose query
facilities offered by LINQ in the upcoming C# 3.0 and ****** 9.0 languages. A
running example introduces basic LINQ concepts. You'll then learn to query
unstructured data using LINQ to XML and relational data with LINQ to SQL.
Finally, you'll see how to extend LINQ for custom applications.
LINQ in Action
will guide you along as you explore this new world of lambda expressions,
query operators, and expression trees. As well, you'll explore the new
features of C# 3.0, ****** 9.0. The book is very practical, anchoring each new
idea with running code. Whether you want to use LINQ to query objects, XML
documents, or relational databases, you will find all the information you need
to get started
But
LINQ in Action
does not stop at the basic code. This book also shows you how LINQ can be used
for advanced processing of data, including coverage of LINQ's extensibility,
which allows querying more data sources than those supported by default. All
code samples are built on a concrete business case. The running example,
LinqBooks, is a personal book cataloging system that shows you how to create
LINQ applications with Visual Studio 2008 and above.
