Determine Whether an Array Contains an Item

Problem

You want to determine whether an array or list contains a specific item.

Solution

To determine whether a list contains a specific item, use the –contains operator:

PS >"Hello","World" contains "Hello" True PS >"Hello","World" contains "There" False

Discussion

The –contains operator is a useful way to quickly determine whether a list contains a specific element. To search a list for items that instead match a pattern, use the –match or –like operators.
