title: string.IsNullOrEmpty using Trim()
body: <p>I want to remove the first line: </p>
  
  <pre><code>                 !string.IsNullOrEmpty(cell.Text) 
  </code></pre>
  
  <p>will this cause any issue?</p>
  
  <p>I ran across this in some code:</p>
  
  <pre><code>                if ((id % 2 == 0)
                      &amp;&amp; !string.IsNullOrEmpty(cell.Text)
                      &amp;&amp; !string.IsNullOrEmpty(cell.Text.Trim())
                      )
  </code></pre>
  
  <p>I think the first string.IsNullOrEmpty would return false on a string with spaces<br>
  and the line with Trim() takes care of that, so the first IsNullOrEmpty is useless</p>
  
  <p>But before I remove the line without the trim I thought I'd run it by the group.</p>
