Powershell - Get Last Logon - powershell

Question

I have a quick script I am trying to reuse from getting computers lastlogon. Due to time constraints I am posting it here for assistance. I am trying to use the display name and even tried using the sam, but no luck.
$results = #()
$CompanyUsers = import-csv c:\bin\users.csv
foreach ($i in $CompanyUsers)
{
$results += Get-Aduser -Filter $i.sam -Properties * | select Name, Lastlogondate
#$results += Get-Aduser -Filter {displayname -eq $i.displayname} -Properties * | select Name, Lastlogondate
}
$results | export-csv c:\bin\Userslogon.csv
I get syntax errors. I can manually put in the values so I am thinking it has to do with data types extracted from the array. Suggestions would be appreciated!
SAM ERROR:

Thanks for the suggestions. I found a way to get this to work:
# Create array of users
$results = #()
$Users = Get-Content C:\bin\fullnames.txt
# Get last logon date
foreach($i in $Users)
{
$results += Get-ADUser -ldapfilter "(displayname=$i)" -Property * | Select-Object -Property name, samaccountname, lastlogondate
}
# Export results to csv file
$results | export-csv c:\bin\logonusers.csv

Answer 1

Try one of these:
Get-Aduser -Filter "samaccountname -eq '$i.sam'" -Properties *
Get-Aduser -Filter "displayname -eq '$i.displayname'" -Properties *
The samaccountname will be faster, since that's an indexed property.

Answer 2

# Create array of users
$results = #()
$Users = Get-Content C:\bin\fullnames.txt
# Get last logon date
foreach($i in $Users)
{
$results += Get-ADUser -ldapfilter "(displayname=$i)" -Property * | Select-Object -Property name, samaccountname, lastlogondate
}
# Export results to csv file
$results | export-csv c:\bin\logonusers.csv
