## LINQ SkipWhileDynamic Method

The LINQ SkipWhileDynamic method bypasses elements in a sequence as long as a specified condition is true and then returns the remaining elements. You can use a dynamic string expression to create the predicate.
 
In this example, we will create a list of product and ordering them descending per type and skipping all `paid` products (instead of using a `where` clause).
