Writing array elements one per line in a string

I have some items in an array which need to be written to out-printer, one per line. Â Easy enough while they’re still in an array, Â but I need to list them in the middle of some other text, but still showing each on its own line. For simplicity’s sake, below is an example:

$test = 'red', 'blue', 'yellow'

$myString = "These are colors: $test"

This yields: Â These are colors: red blue yellow

How can I get it to yield:

These are colors:




?? I’m sure there’s an easy way to do this. Â I understand that it’s due to the fact that I’m forcing the array contents into a string, but I’ve tried a few ways of inserting nr, but nothing I’ve tried works. Also my search-fu didn’t yield any solutions to the problem.


So, couple things. You’re relying a bit on some under-the-hood sneakery PowerShell does when you give it a variable, in double quotes, that contains multiple objects. You won’t get a ton of control over that behavior. What you probably need to do is join the array into a string, using CRLF as a delimiter.

$string = $test -join "-n"

Except instead of dash-n, put backtick-n. The forums software sometimes freaks about back ticks, so I didn’t type it here. Anyway, backtick-N is a newline. Experiment a bit; you may need a backtick-r and backtick-n to get newline and return. The -join operator will take all the elements in the array and merge them into a single string, separated by the delimiter that follows the operator.

Groovy – that worked! Â I had made some split/join attempts, but never successful.

Thanks for the assistance, Don!
