PowerShell script appending to PSObject

I need to identify which servers in my environment have WSMan enabled.  When querying the servers manually they break down into three groups:

1. WSMan is enabled and the server is pingable
2. WSMan not enabled and the server is pingable
3. The server is not pingable

I played around with outputting the results into three separate files, but that seemed stupid so I tried this thinking I could append to the PSObject:

$results = @()

foreach ($server in (Get-Content .\servers.txt)) {
  if (Test-Connection $server -Count 1 -Quiet) {
    if (Test-WSMan -ComputerName $server) {
      $results += New-Object -TypeName PSObject -Property @{
        Name = $server
        Result=  'Success'
      }
    }
    else {
      $results += New-Object -TypeName PSObject -Property @{
        Name = $server
        Result = 'NoWSMan'
      }
    }
  }
  else {
    $results += New-Object -TypeName PSObject -Property {
      Name = $server
      Result = 'NotPingable'
    }
  }
}

$results | Select-Object name,result | Export-Csv "$env:USERPROFILE\Desktop\results.csv" -NoTypeInformation

Select allOpen in new window

It worked except the results overwrote each other and the resulting .csv file only contained one server.  Any ideas?
