Issue for import-csv and foreach - powershell

Question

I want to import a csv, then delete from AD several objects
$ImportComputer = "C:\Users\deng\Desktop\ComputerLastlogondateformatBis.csv"
Import-Module ActiveDirectory
foreach ($Computer in(Import-Csv -Path C:\Users\deng\Desktop\ComputerLastlogondateformatBis.csv))
{
Remove-ADObject -Identity $Computer.'Computer'
these two object exist in AD, but I cannot seem to find out why it is not working.
see below error message:
Remove-ADObject : Cannot find an object with identity: 'fr-borr-mac' under: 'DC=PII,DC=net'.
At C:\Users\deng\OneDrive - Aptus Health\Script\Export.ps1:7 char:1
+ Remove-ADObject -Identity $Computer.'Computer'
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : ObjectNotFound: (fr-borr-mac:ADObject) [Remove-ADObject], ADIdentityNotFoundException

Remove-ADObject : Cannot find an object with identity: 'jlinmacfr' under: 'DC=PII,DC=net'.
At C:\Users\deng\OneDrive - Aptus Health\Script\Export.ps1:7 char:1
+ Remove-ADObject -Identity $Computer.'Computer'

Content of the CSV below:
Computer
--------
fr-borr-mac
jlinmacfr
Could anyone give input on this?

Answer 1

The -Identity parameter on the *-ADObject commands expect either a DistinguishedName or Guid value. If you are wanting to work with SamAccountName or some other attribute, you should consider using the *-ADComputer or using -Filter to find your objects.
# Using Remove-ADObject
Remove-ADObject -Filter "SamAccountName -eq '$($Computer.Computer)'"
# Using Remove-ADComputer
Remove-ADComputer -Identity $Computer.Computer
Alternatively, you can use Get-ADComputer or Get-ADObject to retrieve your object first and then pipe that into Remove-ADObject.
Get-ADObject -Filter "SamAccountName -eq '$($Computer.Computer)'" | Remove-ADObject
See the Remove-ADObject documentation for the following excerpt regarding explicitly binding to -Identity:
Specifies an Active Directory object by providing one of the following
property values. The identifier in parentheses is the Lightweight
Directory Access Protocol (LDAP) display name for the attribute. The
acceptable values for this parameter are:
A distinguished name
A GUID (objectGUID)
For piping an object into Remove-ADObject, the following excerpt applies, which is why you can use a Get-AD* command and pipe the result into the Remove-ADObject:
This parameter can also get this object through the pipeline or you
can set this parameter to an object instance.
Derived types, such as the following, are also accepted:
Microsoft.ActiveDirectory.Management.ADGroup
Microsoft.ActiveDirectory.Management.ADUser
Microsoft.ActiveDirectory.Management.ADComputer
Microsoft.ActiveDirectory.Management.ADServiceAccount
Microsoft.ActiveDirectory.Management.ADFineGrainedPasswordPolicy
Microsoft.ActiveDirectory.Management.ADDomain
