Question

I’m new to PowerShell so this will probably be easy to answer. Suppose I create an array like so:

$array1 = "a", "b", "c"

Then I create another array:

$array2 = $array1|select-object{$_}

What I would like to do is to join all the values in $array2 so I end up with the string “a b c”, but using -join ” ” on $array2 just produces an empty result. Can someone explain to me how I can solve this?

Answer 1

Just replace $array2 = $array1|select-object{$_} with $array2 = $array1 | select-object or $array2 = $array1

$array1 = "a", "b", "c"

#expected output: a b c
$array1 -join " "

#here it is
$array2 = $array1 | select-object

#expected output: a b c
$array2 -join " "

#here it is
$array2 = $array1

#expected output: a b c
$array2 -join " "
