Head First C# Code: Chapter 15, LINQ
It's a data-driven world... you better know how to live in it.
Gone are the days when you could program for days, even weeks, without dealing with loads of data. But today, everything is about data. In fact, you'll often have to work with data from more than one place... and in more than one format. Databases, XML, collections from other programs... it's all part of the job of a good C# programmer. And that's where LINQ comes in. LINQ not only lets you query data in a simple, intuitive way, but it lets you group data, and merge data from different data sources.
