title: How do I use DateTime.TryParse with a Nullable<DateTime>?
body: <p>I want to use the DateTime.TryParse method to get the datetime value of a string into a Nullable.  But when I try this:</p>
  
  <pre><code>DateTime? d;
  bool success = DateTime.TryParse("some date text", out (DateTime)d);
  </code></pre>
  
  <p>the compiler tells me </p>
  
  <blockquote>
    <p>'out' argument is not classified as a variable</p>
  </blockquote>
  
  <p>Not sure what I need to do here.  I've also tried: </p>
  
  <pre><code>out (DateTime)d.Value 
  </code></pre>
  
  <p>and that doesn't work either.  Any ideas?</p>
