title: Check if a string is null or empty, otherwise trim it
body: <p>I tried the following:</p>
  
  <pre><code>dummy.Title = ds1Question.Title.null ? "Dummy title" : ds1Question.Title.Trim();
  </code></pre>
  
  <p>I was expecting to see something like <code>nullorempty</code> with intellisense but it seems there is nothing that can do that. Is there another way I can do this?</p>
