To find Time Difference using C#

Question

Hello I was looking for C# objects and properties to find the time difference between two dates in hh:mm format. date1 =  12/21/2007 10:20 pm  date2 =  12/22/2007 10:35 pm My result should be time difference between date2 and date1 which would be in the format of 24:15(hh:mm) I used Timespan and DateTime classes but they return either the total hours or total minutes. But not the time difference in hh:mm format. Any help will be appreciated. Thanks Prasanna.

The code I posted earlier will still work in fact :) I was worried that if the number of hours went above 99 that the Int32.ToString(00) method might truncate it to 2 digits but I've just tried it and it still works fine.

Try this: DateTime dt1 = DateTime.Parse(date1); DateTime dt2 = DateTime.Parse(date2); TimeSpan ts = dt2 - dt1; string diff = (ts.Days * 24 + ts.Hours).ToString(00) + : + ts.Minutes.ToString(00); Console.WriteLine(diff); // 24:15 hopefully I assume you're not going to be using dates more than a few days apart?
