## LINQ SelectToListDynamic Method

The LINQ SelectToListDynamic projects each element of a sequence into a new form and create a List from it. You can use a dynamic string expression to select a specific column.

In this example, we will dynamically select some product properties, cast our list as queryable (a queryable is required for this method), and returns an anonymous list.
