title: Checking if Parameter is Null
body: <p>I'm trying to create a method that determines if my <code>id parameter</code> is null. If that <code>parameter</code> is null, then it should return true. If the <code>id parameter</code> has a value, then it should return false.</p>
  <p>This seems fairly straight forward, but I can't seem to get it to work.</p>

  </ol>

  <p><strong>My Method:</strong></p>
  <pre><code>public bool IsPersonIdNull(int id)
  {
      return id == null ? true : false;
  }
  </code></pre>
