Adding multiple machines in a text file to an SCCM collection via PowerShell

I am trying to add multiple machines from a text file to an SCCM collection via PowerShell. I have created the collection however when l run this command via Config Manager PowerShell :

Get-Content "C:\Users\PhilM\Desktop\ChromeList.txt" | foreach { Add-CMDeviceCollectionDirectMembershipRule -CollectionName "Chrome Installed Desktops" -ResourceID (Get-CMDevice -Name $_).ResourceID }

I get this error :

Add-CMDeviceCollectionDirectMembershipRule : Cannot bind argument to parameter 'ResourceId' because it is null.

At line:1 char:168

+ ... Installed Desktops" -ResourceID (Get-CMDevice -Name $_).ResourceID }

+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+ CategoryInfo : InvalidData: (:) [Add-CMDeviceCol...tMembershipRule], ParameterBindingValidationException

+ FullyQualifiedErrorId : ParameterArgumentValidationErrorNullNotAllowed,Microsoft.ConfigurationManagement.PowerShell.Cmdlets.Collections.AddDeviceCollectionDirectM

That means that at least one of the names was not found, so no ResourceID was passed.

Get-Content "C:\Users\PhilM\Desktop\ChromeList.txt" | ForEach-Object {
	Write-Host "Processing '$($_)'"
	$cmDevice = Get-CMDevice -Name $_ -Fast
	If ($cmDevice) {
		Add-CMDeviceCollectionDirectMembershipRule -CollectionName "Chrome Installed Desktops" -ResourceID $cmDevice.ResourceID
	} Else {
		Write-Warning "Found no CM device '$($_)'!"
	}
}

Many thanks for the assistance and apologies for the delay. What worked for me was to remove the nulls or the empty space in the in the txt file, which l wasn't aware there was.So thanks to Mike T and l also tried using the CSV as method which worked as well so many thanks for that to FOX
