Calling an Array in PowerShell - arrays

Question

I have a string array $Exclude which I want to put into a filter in a Get-WMIObject cmdlet. I have added it at the end but it does not work.
How can I filter out the services that are listed in that array?
$ServicesToExclude = "RemoteRegistry,CpqNicMgmt"
$Exclude = $ServicesToExclude.split(",")
$Services = Get-WmiObject -Class Win32_Service -Filter {State != 'Running' and StartMode = 'Auto' and Name -ne $Exclude}
$Result = foreach ($Service in $Services.Name)
{
Get-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\$Service" |
Where-Object {$_.Start -eq 2 -and $_.DelayedAutoStart -ne 1}|
Select-Object -Property #{label='ServiceName';expression={$_.PSChildName}} |
get-Service
}
If ($Result.count -gt 0){
$Displayname = $Result.displayname
[string] $Line = "`n-----------------------------------------"
$Api.LogScriptEvent( 'Stopped_Auto_Services.ps1',1234,4,"`nStopped Automatic Services$Line `n$($Displayname)")

Answer 1

Filtering an array out of a list is not done on the WMI side. Instead, you should use Where-Object to filter out those services which name is contained in $Exclude.
$Services = Get-WmiObject -Class Win32_Service -Filter {State != 'Running' and StartMode = 'Auto'} |
Where-Object {$Exclude -notcontains $_.Name}

Answer 2

WMI queries do not work well with arrays and need to be done a different way. If you want to keep the filtering on the server side, you can do some work prior to running the command by creating a filter string as shown here:
$Exclude = "RemoteRegistry","CpqNicMgmt"
$StringBuilder = New-Object System.Text.StringBuilder
[void]$StringBuilder.Append("State != 'Running' AND StartMode = 'Auto' AND ")
[void]$StringBuilder.Append("($(($Exclude -replace '^(.*)$','Name != "$1"') -join ' AND '))")
$Query = $StringBuilder.ToString()
$Services = Get-WmiObject -Class Win32_Service -Filter $Query
There may be better ways to accomplish this, but this was the first thing that I could think of to accomplish the goal of your question.
