[C#] How to get HH:mm from two datetimes?

Sai Yang

hi there,

how to get Duration of log in and log out system in the format of HH:mm from two datetime?

I using this code:

DateTime now = DateTime.Now;

TimeSpan hrs = now - timein;

double z = hrs.TotalHours;

if using system for two hours

z = 2.700123 something like that.

it doesn't support my needed.

what I want is like:

e.g

logintime logouttime duration

06/04/2018 23:04:36 07/04/2018 23:05:08 HH:mm or (e.g) z=24:30

format dd/MM/yyyy HH:mm:ss .

Mean 24 hrs and 30 minutes; after 30 minutes z=25:00 hrs. (not 24.5004343534).

Duration should be more than 24 hour upto days log in if using two days will display like 48:30........

How can I display that????

Best regard;

@Sai endDateatime and startDateTime are of DateTime datatype, after subtracting it will give you result in TimeSpan

DateTime Res=Convert.ToDateTime(Convert.ToDateTime(endDatetime)- Convert.ToDateTime(startDatetime)).Tostring("hh\:mm\:ss")
string value=Res.ToString();

I tried this way but error input string was not in a correct format. It could not subtract datetimes.

Simply subtract the dates and convert its its format like
var DurationTime = endDateTime - startDateTime ;

var value = DurationTime.ToString(@"hh\:mm\:ss");
