How can I convert a Powershell list into a string format?

edit

You can use the -join operator to convert a PowerShell list into a string format. Here's an example:

$list = "item1", "item2", "item3"
$string = $list -join ","
Write-Output $string

This will output: item1,item2,item3

In this example, we use the -join operator to concatenate each item in the $list variable with a comma , as a separator. The resulting string is then stored in the $string variable.
