ADSI LDAP search how to return list of DNs

Question

Hallo,
I'm trying to build a function that will have two parameters $Containrer and $Filter
$filter - is a LDAP filer that serach some specific objects
$Containrer - is a container in which $filter should looks for object
Function shoud return list of distinguishedNames ob finded objects
So at first I try make some simple code to transform it into function but I dosn't work.

[Reflection.Assembly]::LoadWithPartialName("Softerra.Adaxes.Adsi")
$admNS = New-Object "Softerra.Adaxes.Adsi.AdmNamespace"
$admService = $admNS.GetServiceDirectly("localhost")
$userSAM = "%samaccountname%"
$searcher = $admService.OpenObject("Adaxes://$GroupsContainerDN", $NULL, $NULL, 0)
$searcher.SearchFilter = "(&(objectClass=group)(extensionAttribute1=$userSAM))"
$searcher.SearchScope = "ADS_SCOPE_SUBTREE"
$searcher.SetPropertiesToLoad(@("distinguishedName"))
$searchResults = $searcher.ExecuteSearch()
$array = @{}
foreach ($object in $searchResults.FetchAll())
{
$DN = $object.Properties["distinguishedName"].value
$array += $DN
}
$searchResults.Dispose()

The code should returned a list of DN's , but I got "You can add another hash table only to a hash table'
Seams that $DN is treated by powershell as a hash table, is it possible to workoroud it somhow?

Hello,

You are declaring $array as a hash table, but trying to work with it as with an array. To remedy the issue, you need to declare it as an array. To do this, replace the following line:
$array = @{}
with the following:
$array = @()
