Powershell - Get-AdUser: Exclude users in array - powershell

Question

I want to generate a list of users, with the exception of a list of names. This exclusion list changes from week to week.
$exclude = #('smith, bob', 'jones, tom', ...)
$csvmaster = #()
$uacct = 'User Account'
$UserID = 'User ID'
$lastname = 'Last Name'
... other attributes
$ulist = get-aduser -filter {enabled -eq 'true'} -properties * | ? {$_.Distinguishedname -like '*Standard User*' -and $_.title -ne $null -and $_.employeenumber -ne $null}
foreach ($u in $ulist)
{
if ($u.name -notmatch $exclude) {
$csvline = New-Object System.Object
$csvline | Add-Member -MemberType NoteProperty -name $UserID -value $u.EmployeeNumber
$csvline | Add-Member -MemberType NoteProperty -name $lastname -value $u.surname
...other attributes
$csvmaster += $csvline
}
}
...Output to csv
When I run this, the names I want to exclude still make it into the list. I also tried -notcontains and excluding them like this:
$ulist = get-aduser -filter {enabled -eq 'true'} -properties * | ? {$_.Distinguishedname -like '*Standard User*' -and $_.title -ne $null -and $_.employeenumber -ne $null -and $_.name -notmatch $exclude}
This behaves the same way.
Cheers.

Answer 1

So I think my problem was the way Get-ADUser accepts input value. And/Or my logic in general. I changed the code to this:
$exclude = #( ..list..of..names..)
$csvline = #()
$ulist = get-aduser ...
foreach ($u in $ulist)
{
if ($exclude -notcontains $u.name)
{
...
$csvline += $u.name
}
}
And it is doing what I need.
