title: Add column and assign value to an existing array
body: <p>I want to add a column and a value to an existing array generated from a CSV.</p>
  
  <p>This is my code:</p>
  
  <pre><code>$mycsv = "C:\Users\test\Documents\serveurs.csv"
  $servers = Import-Csv $mycsv
  </code></pre>
  
  <p>This is the result:</p>
  
  <pre>
  ServerName                              Ip
  ----------                              --
  Castor                                  172.22.0.64
  Pollux                                  172.22.0.67
  </pre>
  
  <p>I want to add new column with value for each ServerName, like this:</p>
  
  <pre>
  ServerName                              Ip                  Available
  ----------                              --                  ---------
  Castor                                  172.22.0.64         Yes
  Pollux                                  172.22.0.67         No
  </pre>
  
  <p>I tried the code below:</p>
  
  <pre><code>$item = New-Object PSObject
  $item | Add-Member -Type NoteProperty -Name 'Available' -Value 'Yes'
  
  $servers += $item
  </code></pre>
  
  <p>But it's actually not working, can anyone help me? </p>
  
  <p>The final idea is to have value assigned if the server is reachable or not over the network, using <code>Test-Connection</code> cmdlet.</p>
