Combining two Datetime values

I'm pretty new to coding so sorry if my question has an obvious answer but I didn't find anything like that via the search.

I'm currently trying to make a time tracker database by using Windows Forms in C#.

My oroblem is the GUI has two DateTimePicker: one displays the hours (dateTimePicker1) which you can choose, and the other one displays the minutes (dateTimePicker2) you can choose.

Both of them are starting with the current time when the form is loading.

I'm now trying to combine those two so that I get a string which gives me both hours and minutes with the chosen time.

If someone could help me here I'd be really glad because I'm currently out of ideas....

Are you looking for this?

  // myDatePicker displays date 
  DateTime day = myDatePicker.Value.Date;
  // myTimePicker displays time
  var timeOffset = myTimePicker.Value.TimeOfDay;

  // combined value (day and time)
  DateTime result = day + timeOffset;

In case you have three DatePickers (date, hour and minutes):

  // myDatePicker displays date 
  DateTime day = myDatePicker.Value.Date;

  DateTime result = day
    .AddHours(myHourPicker.Value.Hour)
    .AddMinutes(myMinutePicker.Value.Minute);

To display in required format use formatting:

  // Hours and minutes
  String text = result.ToString("hh:mm");

Do you mean like this?

// take hour from first datetimepicker
DateTime hour = dateTimePicker1.Value.Hour;
// take minute from second datetimepicker
DateTime minute = dateTimePicker2.Value.Minute;
// combine hour and minute into an object
DateTime hourAndMinute = hour + minute;
// convert the combined DateTime into string
hourAndMinute.ToString("hh:mm");

If you want to convert it to string with different format you can check it here http://www.dotnetperls.com/datetime-format

If you actually need to represent length of time you should use this one http://www.dotnetperls.com/timespan

Mark as an answer if it help you :)
