compare-object output not wanted

I am comparing two csv files and I noticed it was reading the line per line, which I did not want.  I have figured out how to use the select -expand property in the compare-object import to help it find the difference in logonid vs doing line by line.  MY issue is once a logon id is found I want to output all the other colums that are associated with the logonid to my log file.  How can I do that.  Below is a sample and it works if I allow a line by line but I need to filter by logon id and when found output the whole row of info for that user   How can I accomplish this. example of my input file.  logonid name displayname and so on.  

importFile1 = Import-Csv -Path $file1 
$importFile2 = Import-Csv -Path $file2
$compareObj = compare-Object -ReferenceObject (import-csv -Path $file1 | select -expandProperty logonid) -DifferenceObject (Import-Csv -Path $file2 | select -expandProperty logonid)

foreach($conflict in $compareobj){
Write-Host $conflict

 if($_.sideindicator -eq "=>"){
$ChangeFile = $file2Path
$note = "Looks Like Addition to the Group has occurred"
}

else{
$ChangeFile = $file1Path
$note = "Looks Like an Object was removed from this group"

}

New-Object -TypeName PSCustomObject -Property @{
            LogonID = $conflict.inputobject.logonid
            Name = $conflict.inputobject.name
            DisplayName = $conflict.inputobject.displayname
            AccountDisabled = $conflict.inputobject.AccountDisabled
            GroupName = $conflict.inputobject.groupname
            NestedMember = $conflict.inputobject.nestedmember
            GroupEmpty = $conflict.inputobject.GroupEmpty
            ParentGroup = $conflict.inputobject.ParentGroup
            ConflictFile = $ChangeFile
            Note = $note
           
            } | select-object LogonID,Name,Displayname,AccountDisabled,GroupName,NestedMember,GroupEmpty,ParentGroup,ConFlictFile,Note | Export-Csv $LogFile -Append -NoTypeInformation
}

}
