Importing a CSV to fill-in some AD fields

Hi,

we  have a large CSV with some additional information for some users. Additional phonenumbers, www-pages etc. 

A sample line from the CSV is this:

name,naam,sAMAccountName,info,mail,xxx,ipPhone,pp,department,mobile,facsimileTelephoneNumber,l,postalCode,telephoneNumber,xxxxx,company,streetAddress,wWWHomePage,homePhone,Kolom1,title
Fred Brandt,Fred Brandt,fbrandt,Fred,fbrandt@XXX.nl,Brandt,a,b,Facilitaire zaken,+31 (0) 6 5571 6568,,Zoetermeer,2718 SG,+31 (0)79 3467,+31 (0)79 346 7800,XXX B.V.,Signaalrood 60,aap.nl,208,c,Medewerker

The command i use is this one:
Import-Csv c:\evo-1.csv | Foreach-object {get-ADUser -filter {name -eq $_.name} | set-aduser -department $_.department -mobile $_.mobile -city $_.l -postalcode $_.postalcode -OfficePhone $_.telephoneNumber -company $_.company -streetaddress $_.streetaddress -HomePage $_.wWWHomePage -homePhone $_.homePhone -title $_.title}

It gives me an error: property name not found in object of type: System.Management.Automation.PSCustomObject. If I isolate only this user and replace the $_.name with only "Fred Brandt" it works. But since i have over 300 users, it is no solution to isolate them all and import the info one by one, anyone who can help me out?

Thanks in advance
