Trouble getting Powershell IF THEN to work

I have a question about IF THEN in powershell.
I have a text file that contains First names
I have an array with $Folder.fullname or $Folder.name
I want to ignore all items that match Firstname

$firstname = Get-Content -Path 'C:\temp\file.txt'
$Folders = Get-Childitem -path '\\Server1\Folders' -Direcotry

Foreach ($folder in $folders)
{
If ($folder.name -match $firstname) 
           {
                 <Do Something>
           }
}
