## LINQ OrderByDescendingDynamic Method

​

The LINQ OrderByDescendingDynamic method sorts the elements of a sequence in descending order. You can use a dynamic string expression to specify columns.

​

In this example, we will create a list of product and order them dynamically by their name in descending order.
