This type is enumerable because it inherits from IEnumerable<T>.
The extension methods ThenBy and ThenByDescending operate on objects of type IOrderedEnumerable<TElement>. An object of type IOrderedEnumerable<TElement> can be obtained by calling one of the primary sort methods, OrderBy or OrderByDescending, which return an IOrderedEnumerable<TElement>. ThenBy and ThenByDescending, the subordinate sort methods, in turn also return an object of type IOrderedEnumerable<TElement>. This design allows for any number of consecutive calls to ThenBy or ThenByDescending, where each call performs a subordinate ordering on the sorted data returned from the previous call.
The following example demonstrates how to perform a primary and secondary ordering on an array of strings. It also demonstrates that the resulting IOrderedEnumerable<TElement> is enumerable.
// Create an array of strings to sort. string[] fruits = { "apricot", "orange", "banana", "mango", "apple", "grape", "strawberry" }; // Sort the strings first by their length and then alphabetically // by passing the identity selector function. IOrderedEnumerable<string> sortedFruits1 = fruits.OrderBy(fruit => fruit.Length).ThenBy(fruit => fruit); // Output the resulting sequence of strings. foreach (string fruit in sortedFruits1) Console.WriteLine(fruit); // This code produces the following output: // // apple // grape // mango // banana // orange // apricot // strawberry
