Filtering & Ordering

Most queries you write boil down to two questions: "which rows do I want?" and "in what order do I want them?" LINQ answers the first question with operators like Where, OfType, Distinct, Take, and Skip, and the second with OrderBy, ThenBy, and Reverse. This lesson covers each of those operators, the overloads that matter in real code, and the performance characteristics that decide how you chain them.
