LINQ | Sorting Operator | ThenByDescending
In LINQ, sorting operators are used to rearrange the given sequence in ascending or descending order based on one or more attributes. There are 5 different types of sorting operators are available in LINQ:
The ThenByDescending operator is used to implement secondary sort in descending order. The multiple sorting is supported by ThenByDescending operator. Generally, ThenByDescending method is used with the OrderBy method. The OrderBy() method first sort the elements of the sequence or collection in descending order after that ThenByDescending() method is used to again sort the result of OrderBy() method in descending order. Or in other words, in LINQ, the collection is the first sort according to the primary field which is given by OrderBy method after that the result of the primary sort is again sorted by the secondary field that is given by the ThenByDescending method.
