LINQ for VB 2005

本文介绍了Microsoft推出的LINQ技术,该技术旨在解决对象导向应用程序与关系型数据整合的问题。通过LINQ,开发者可以轻松地从不同数据源(如SQL Server数据库、XML文件及数组等)中查询并管理数据。本文还提供了关于LINQ to Objects、LINQ to ADO.NET及LINQ to XML三个主要部分的详细指导。

At the Microsoft Professional Developers Conference (PDC) 2005, Microsoft previewed a new technology, Language-Integrated Query (LINQ). It captured a lot of attention because it addressed the fundamental issue of merging object-oriented applications with relational data. The LINQ Project team demonstrated how to use LINQ to query a variety of data sources, such as a SQL Server database, an XML file, and an array, and how to manage the data using an object-oriented approach.

Fabio Ferracchiati has written a comprehensive guide to the three main parts of the LINQ May 2006 CTP: managing in-memory data (LINQ to Objects), accessing relational databases (LINQ to ADO .NET), and manipulating XML documents (LINQ to XML). Each chapter offers many practical examples that you can try yourself with the downloadable source code. Youll quickly learn everything you want and need to know about LINQ by actually using LINQ.

The future of .NET data access is already hereand its a very bright one!
