title: String date time format
body: <p>I am using the Vimeo API and I want to convert the string &lt;upload_date> to a short date format, {0:d} or {0:dd/mm/yyyy}.</p>
  
  <p>This is my code but it doesn't seem to be working for me.</p>
  
  <pre><code>    select new VimeoVideo
              {
                  Date = String.Format("{0:d}",(item.Element("upload_date").Value)),
              };
          return Vids.ToList();
      }
  
      public class VimeoVideo
      {
          public string Date { get; set; }
      }
  </code></pre>
