PowerShell to SQL- Array function always return element 0 first

Any Array value if you have like

$searcher.propertiesToLoad.Add("xxxxx")
$myarray.Columns.Add("DistinguishedName")

Always, Always put "| Out-Null" behind to prevent the null element feed Function first and get "False" then return "0" back.
So your Table doesn't need to add one more "Ghost" column
