PowerShell Love – Converting a comma delimited string to an array by Peter

PowerShell takes a while to learn – especially if you have an aversion to manuals as I do – I prefer to learn on the fly. So, when I wanted to convert a variable containing a comma delimited string into an array I was lost. After a bit of playing and ‘binging’ I found that it was actually very very easy:

# start with a string
$roles = "db_owner"

# now it’s an array of 1 element
$roles = ,$roles

Sweet!

Good shortcut.

Another way is

$roles = @($roles)
or
$roles = @("db_owner")

The array notation is useful when you want to ensure you have an array, especially when items are returned from a function.

$roles = @(Get-Roles)
