How to check if a string contains a number in powershell

Question

How do I check if a string contains any numeric value.

Ex: paul123

The above example contains numeric value so I should get the output as true.

Answer 1

Use a regular expression match:

'paul123' -match '\d'

\d matches a digit (0-9), so the expression will evaluate to true if the string contains at least one digit.
