                Sent = u.DateSent,
                Reply = u.DateReply,

                ResponseTime = Reply - Sent
            });

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?

Answer 1

You can change the ResponseTime type to TimeSpan and than do the following:

DateTime dateSent = new DateTime(2012, 10, 30, 2, 0, 0);
DateTime dateReply = new DateTime(2012, 10, 30, 4, 30, 0);

TimeSpan difference = dateReply - dateSent;
Console.WriteLine("{0}:{1}", difference.Hours, difference.Minutes);

I just put the Console.WriteLine so you could see how I’m getting the Hour and Minute just like the way you want. From milliseconds, you could create a new TimeSpan passing the milliseconds to the constructor, and again you could get the Hour/Minute in this newly created TimeSpan.

I just put the hardcoded dates so you could actually see the usage based on your example.

I hope it helps.
