Regular Expressions with Windows PowerShell To use all of .NET's regex processing functionality with PowerShell, create a regular expression object by instantiating the System.Text.RegularExpressions.Regex class. PowerShell provides a handy shortcut if you want to use the Regex() constructor that takes a string with your regular expression as the only parameter. $regex = [regex] '\W+' compiles the regular expression \W+ (which matches one or more non-word characters) and stores the result in the variable $regex.

If you want to, you can set up a For loop that loops through that set of numbers, methodically adding each value to the array, one-by-one. Alternatively, you can use PowerShell’s range operator, like so:
