Chapter 9. LINQ and lambdas: Get control of your data
It’s a data-driven world...we all need to know how to live in it.
Gone are the days when you could program for days, even weeks, without dealing with loads of data. Today, everything is about data, and that’s where LINQ comes in. LINQ is a feature of C# and .NET that not only lets you query data in your .NET collections in an intuitive way, but lets you group data and merge data from different data sources. You’ll add unit tests to make sure your code is working the way you want. Once you’ve got the hang of wrangling your data into manageable chunks, you can use lambda expressions to refactor your C# code to make it even more expressive
