Separate items in array with comma

-

good day guys, i'm trying separate items in array comma can't work.

i've been trying before array of ips, hotfix ids.

please me this. in advance!

$patch = get-wmiobject win32_quickfixengineering -computername "server1" | sort-object installedon -descending| select-object -first 5

$hotfixid = $null

$patch.hotfixid | % { $hotfixid += $_ } 

$hotfixid -join ","

i keep getting  results this, same ips. kb3135445kb3134214kb3133043kb3127220kb3126593


use

$hotfixid = @()

instead of assigning $null, make array.
