diff between two days, in hours

I do not uderstand why the result of:

(DateTime.Now.Subtract(user.created_time.Value.Date)).Hours

is 23.

where:

DateTime.Now is:{3/30/2010 12:00:00 AM}

and

user.created_time.Value.Date is : {3/24/2010 12:00:00 AM开发者_StackOverflow中文版}

Does it make sense for anybody?

ps: I want to select all users created in last 72 hours so i suppose that is the way i should do...

Hours just gives you the hours, and ignores the other fields like days. Use TotalHours instead.

The Hours property gives you the hours component of the TimeSpan. Thus, if a TimeSpan is more than a day, Hours will give you only the hours part, without any full days.

You want the TotalHours instead.
