"LINQ资料word版,包含了对LINQ的详细介绍,适用于C#和VisualBasic开发者,内容涵盖LINQ的基本概念、入门教程、项目创建、IDE支持、编程指南以及各种LINQ子技术如LINQ to Objects、LINQ to XML、LINQ to ADO.NET等,还有额外的LINQ资源链接。" LINQ,全称Language Integrated Query,是C#和Visual Basic.NET中的一项创新技术,首次在Visual Studio 2008中推出。它的核心目标是将查询数据的功能直接整合到编程语言中,提供了一种统一的、易于理解和使用的查询语法。通过LINQ,开发者可以用一种更自然、更接近于SQL的语句来查询各种数据源,无论是内存中的数据结构、XML文档还是数据库。 LINQ简介部分介绍了LINQ能解决的问题,比如简化数据访问,增强代码的可读性和可维护性。它允许开发者用相同的查询语法处理不同的数据源,降低了学习新查询语言的难度。 C#中的LINQ入门和VisualBasic中的LINQ入门分别针对这两种语言的开发者,提供快速上手的指导,让开发者了解如何在各自的编程环境中使用LINQ进行查询操作。 如何创建LINQ项目这部分详细阐述了创建支持LINQ的.NET Framework项目所需的配置,包括需要的框架版本、引用的库和必要的命名空间。 对LINQ的Visual Studio IDE和工具支持这部分则讨论了IDE如何帮助开发者更好地利用LINQ,如对象关系设计器、查询调试以及其他的集成开发环境特性。 LINQ常规编程指南是一个重要的部分,它提供了链接到标准查询运算符、表达式树和查询提供程序的详细信息,这些都是编写高效LINQ查询的基础。 LINQ to Objects允许开发者查询内存中的数据结构,如数组、列表等,而LINQ to XML则提供了处理XML文档的强类型、高性能的API,同时支持LINQ查询表达式。 对于数据库相关的查询,LINQ to ADO.NET(包括LINQ to DataSet和LINQ to SQL)提供了与数据库交互的能力。LINQ to SQL是一个轻量级的ORM(对象关系映射)工具,用于将数据库表映射为.NET类,方便进行对象化操作。 补充的LINQ资源部分则是指向更多LINQ相关教程、文档和社区资源的链接,帮助开发者深入学习和解决问题。 这份资料详尽地介绍了LINQ技术的各个方面,无论你是初学者还是经验丰富的开发者,都能从中受益,提升数据查询和处理的能力。

LINQ中文学习资料和LINQ 随身参考手册,其中LINQ 随身参考手册是英文版的,但内容不错。 LINQ 随身参考手册介绍:   Ready to take advantage of LINQ with C# 3.0? This guide has the detail you need to grasp Microsoft’s new querying technology, and concise explanations to help you learn it quickly. And once you begin to apply LINQ, the book serves as an on-the-job reference when you need immediate reminders. All the examples in the LINQ Pocket Reference are preloaded into LINQPad, the highly praised utility that lets you work with LINQ interactively. Created by the authors and free to download, LINQPad will not only help you learn LINQ, it will have you thinking in LINQ. This reference explains: LINQ’s key concepts, such as deferred execution, iterator chaining, and type inference in lambda expressions The differences between local and interpreted queries C# 3.0′s query syntax in detail-including multiple generators, joining, grouping, query continuations, and more Query syntax versus lambda syntax, and mixed syntax queries Composition and projection strategies for complex queries All of LINQ’s 40-plus query operators How to write efficient LINQ to SQL queries How to build expression trees from scratch All of LINQ to XML’s types and their advanced useLINQ promises to be the locus of a thriving ecosystem for many years to come. This small book gives you a huge head start. “The authors built a tool (LINQPad) that lets you experiment with LINQ interactively in a way that the designers of LINQ themselves don’t support, and the tool has all kinds of wonderful features that LINQ, SQL and Regular Expression programmers alike will want to use regularly long after they’ve read the book.” -Chris Sells, Connected Systems Program Manager, Microsoft   About the Author   Joseph Albahari is a core C# design architect at Egton Medical Information Systems, the largest primary healthcare software supplier in the UK. He has been developing large-scale enterprise applications on .NET and other platforms for more than 15 years, working in medical, telecommunication and education industries. Joseph specializes in writing custom components and controls, and has designed application component frameworks for three companies.   Ben Albahari is currently involved in the bioinformatics business. He was a Program Manager at Microsoft for 5 years, where he worked on several projects, including the .NET Compact Framework and ADO.NET.   He was the cofounder of Genamics, a provider of tools for C# and J++ programmers, as well as software for DNA and protein sequence analysis. He is a co-author of C# Essentials, the first C# book from O’Reilly, and of previous editions of C# in a Nutshell.
