Case sensitive “Contains” operator in PowerShell

In PowerShell, we can use the –contains operator to determine if a string contains something that we care looking for. Here is an example:

$collection -contains "One"

In this example, True would be returned. In the next example, True would also be returned.

$collection -contains "one"
