-contains

Contains is a conditional operator that will test for the existence of one item in a collection, array or hashtable.

Syntax
      expression -contains expression

Contains is an exact (but case-insensitive) match and will ignore wildcards.

To examine the contents of values within a string, either use a wildcard -match or -split the string into an array.

This operator returns True or False.

PS C:\> $demoArray = 'alpha', 'beta', 'New York'
PS C:\> $demoArray -contains "Alpha"
True
PS C:\> $demoArray -contains 'New'
False
PS C:\> $demoArray -contains 'New york'
True

PS C:\> $string = 'alpha, beta, California'
PS C:\> $string -contains 'alpha'
False
PS C:\> $string -split ',' -contains 'alpha'
