  <pre><code>                Sent = u.DateSent,
                  Reply = u.DateReply,
  
                  ResponseTime = Reply - Sent
              });
  </code></pre>
  
  <p>which give me the time different between the two datatime is 10 days, but i want to calculate the hour and minute during the time interval,(for example if datesent is 09/02/2011 2:00 pm , and dateReply is 09/02/2011 4:30 pm , then the response time should be 2:30 ) still havent figure this out, anyone has idea, either format it in linq or do it over the view page?</p>
