书籍简介

如果您问过自己“为什么我不能用我已经了解的语言开发数据库和 XML 查询？”，那么语言集成查询 (LINQ) 就是您的选择。LINQ For Dummies 向您介绍了 LINQ 和 Framework 技术，因此您可以使用 LINQ 查询任何对象、任何数据集、任何类型的 XML 和 SQL Server — 毫无疑问。

这本简明扼要的指南为您提供了 LINQ 的全面概述，从了解它执行的任务到让 LINQ 与 Visual Basic 和 Visual Studio 2005 协同工作。它解释了Framework 中的四个 LINQ 提供程序、访问数据的简单方法以及如何使用 LINQ 用更少的代码编写更高效的应用程序。还有关于将第三方提供程序与 LINQ 相结合以创建更强大的应用程序的明确指导。通过这本全面的指南，您将了解如何：

使用一种查询语言来处理所有 Microsoft 语言

检查语言扩展并使用扩展方法、部分方法表达式和查询表达式

LINQ 到 DataSet 运算符、SQL 服务器操作、XML API 或 Active Directory

处理数据库 — 下载并安装 Northwind 数据库、生成 Northwind 实体类并创建 Northwind XML 映射文件

创建部分类示例、部分方法示例和数据库修改示例

使用 LINQ 对象

使用 Visual Basic 和 C# 查询数据库

作为附加奖励，您可以访问配套网站，查看 C# 和 Visual Basic 中的 LINQ 示例。使用 LINQ For Dummies，您将立即与 LINQ 建立联系，并了解如何查询几乎任何内容！

If you’ve asked yourself “Why can’t I develop database and XML queries in a language I already know?”, then Language INtegrated Query, or LINQ, is for you. LINQ For Dummies introduces you to LINQ and the Framework technologies, so you can use LINQ to query any object, any data set, any kind of XML, and SQL Server—no questions asked.

This plain-English guide gives you a thorough overview of LINQ, from understanding the tasks it performs to making LINQ work with both Visual Basic and Visual Studio 2005. It explains the four LINQ providers in the Framework, the easiest ways to go about accessing data, and how to write more efficient applications with less code using LINQ. There’s also clear guidance on combining third-party providers with LINQ to create even more powerful apps. With this single, comprehensive guide, you’ll discover how to:

Use one query language with all Microsoft languages

Examine language extensions and work with extension methods, partial methods, expressions, and query expressions

LINQ to DataSet operators, SQL server operations, XML API, or Active Directory

Deal with databases — download and install the Northwind database, generate Northwind entity classes, and create the Northwind XML mapping file

Create the partial class example, the partial method example, and the database modification example

Use objects with LINQ

Query databases in Visual Basic and C#

As an added bonus, you can visit the companion Web site for LINQ examples in C# and Visual Basic. With LINQ For Dummies, you’ll link up with LINQ in no time and see how you can query almost anything!
