-in operator

As an alternative to the –contains operator you can use the –in operator

 

Repeating the tests from the previous post on –contains

 

PS> $primes = 1,3,5,7,11,13,17,19,23,29,31,37,41,43,47
PS> $candidate = 7
PS> $candidate -in $primes
True

PS> $candidate = 4
PS> $candidate -in $primes
False

 

The –in operator can be used in the simplified where syntax but –contains can’t
