title: Count occurence of data in array
body: <p>I have an array like this:</p>
  
  <pre>OptiPlex 790
  Precision WorkStation T7500
  Precision WorkStation T7400
  Precision T1500
  Precision WorkStation T3500
  CELSIUS R650
  VMware Virtual Platform
  Precision T1500
  OptiPlex GX620</pre>
  
  <p>I want to get the count of array and will add that in new array.</p>
  
  <pre>Element:Count
  OptiPlex 790 1 
  Precision WorkStation T7500 1 
  Precision WorkStation T7500 1</pre>
  
  <p>I want to store this value in new array. So, i will use it later/somewhere else.</p>
  
  <pre><code>$array = @()
  for ($i=1; $i -le $rowMax-1; $i++) {
      $Model = $sheet.Cells.Item($rowModel+$i, $colModel).text
      Write-Host ("I am reading data on row: " + $i)
      $array += $Model
  }
  
  $array | Group
  </code></pre>
  
  <p>At the moment above script is working fine but I don't know how I can add this data to new array.</p>
