Thinking in LINQ: Harnessing the power of functional programing in .NET applications

CHAPTER 4

Refactoring with LINQ

When I help my colleagues refactor their loops by using LINQ, they always ask me, “How do you know what LINQ operator to use?” I am sure my colleagues are not alone. This chapter is dedicated to providing detailed examples to help answer that question.

After reading this chapter, you should be able to look at code snippets and know which ones can be replaced with a LINQ query. Think of LINQ operators as similar to Lego blocks. After you know how to use them, you can see and replace a repetitive pattern in your code by gluing together LINQ operators, leading to cleaner, more-intuitive, and thus more maintainable ...
