Description

Test whether an element is in a list.

Contains returns True if the element Value is in the list and False otherwise. This method only indicates whether the element is in the list or not; use IndexOf to get the index of an element in a list.

Since the search for the element is linear, it is an O(n) operation for a list with n entries.
