How can I add group membership information to this csv export?

Baron164 

$fullReport=@()
$AllUsers=Get-ADUser -Filter "uidNumber -ge 0" -Properties Name,givenName,sn,uidNumber,userPrincipalName 
foreach ($singleuser in $AllUsers){
    $Report=[PSCustomObject]@{
        Name = $singleuser.Name
        givenName=$singleuser.GivenName
        sn=$singleuser.sn
        uidNumber=$singleuser.uidNumber
        userPrincipalName=$singleuser.userPrincipalName
    }
    $AllGroups=Get-ADPrincipalGroupMembership $singleuser.SamAccountName
    for ($i = 0; $i -lt $AllGroups.name.count; $i++) {
    $GroupGid=Get-ADGroup -Properties gidNumber -Identity $AllGroups[$i].SamAccountName
        $Report | Add-Member -NotePropertyName "Group$i" -NotePropertyValue $GroupGid.gidNumber
    }
    $fullReport+=$Report 

}

Let me know 🙂
