title: Sort DataRow[] using LINQ
body: <p>DataRow[] drTest contains <code>System.Data.DataRow</code>, say, contains 10 <code>DataRow</code>'s. Inside of each DataRow, I have an ItemArray that contains <code>Name</code> and <code>Count</code>.
  Now I want to sort the DataRow[] drTest in descending order based on the ItemArray second record count.</p>
  
  <p>Example:</p>
  
  <pre><code>DataRow[] drTest contains 
  
  At [0] Index - ItemArray[0] - "A"
               - ItemArray[1] - 5
  
  At [1] Index - ItemArray[0] - "B"
               - ItemArray[1] - 7
  </code></pre>
  
  <p>I want to order drTest in descending order, so that drTest[1] should come up.</p>
