LINQ, C#'s Language Integrated Query, simplifies the code needed to query, reshape, and aggregate data. Instead of writing complex, nested loops to implement procedures for working with data, LINQ enables a more functional, declarative style. LINQ queries more closely resemble SQL than a procedural language like C. In this course, you'll learn about iterator methods, including their advantages, how to step through and implement them, and how to convert a standard method to an iterator method. You'll also examine filtering and ordering data using LINQ to Objects, using LINQ's let clause, and the purpose of deferred execution. Finally, you'll learn about aggregating, grouping, and joining data using LINQ to Objects. This course was originally created by Global Knowledge (GK).
