تفکر در LINQ: به کارگیری قدرت برنامه‌نویسی تابعی در برنامه‌های .NET

LINQ represents a paradigm shift for developers used to an imperative/object oriented programming style, because LINQ draws on functional programming principles. __Thinking in LINQ__ addresses the differences between these two by providing a set of succinct recipes arranged in several groups, including: * Basic and extended LINQ operators * Text processing * Loop refactoring * Monitoring code health * Reactive Extensions (Rx.NET) * Building domain-specific languages Using the familiar "recipes" approach, __Thinking in LINQ__ shows you how to approach building LINQ-based solutions, how such solutions are different from what you already know, and why they’re better. The recipes cover a wide range of real-world problems, from using LINQ to replace existing loops, to writing your own Swype-like keyboard entry routines, to finding duplicate files on your hard drive. The goal of these recipes is to get you "thinking in LINQ," so you can use the techniques in your own code to write more efficient and concise data-intensive applications. Annotation LINQ draws on principles of functional programming and represents a paradigm shift for developers used to an imperative/object oriented programming style. Thinking in LINQ explains the benefits of functional programming built into LINQ, allowing developers to use these techniques write more efficient and concise data-intensive applications. While other books on the subject merely scratch the surface in terms of problem solving using LINQ, Thinking in LINQ shows readers how use functional programming techniques to solve common every-day problems as well as more complex problems using LINQ s features. LINQ lets you write code that resembles natural language and is easier to debug compared to traditional loops and branching statements. The purpose of a well written LINQ Query will be immediately evident unlike the looping construct so commonly used in traditional programming. LINQ operators can be used in unison to orchestrate a solution for complex real world problems.
