Adding time in DateTime in C #

Question

I have a calendar and a text box that contains the time of day. I want to create a date-time that is a combination of the two. I know that I can do this by looking at the clock and coins and then adding them to the DateTime calendar, but that seems pretty dirty.

Is there a better way?

Answer 1

You can use the DateTime.Add () method to add time to the date.

DateTime date = DateTime.Now; TimeSpan time = new TimeSpan(36, 0, 0, 0); DateTime combined = date.Add(time); Console.WriteLine("{0:dddd}", combined); 

You can also create your own time span for parsing the string if that is what you need to do.

Alternatively, you can use other controls. You did not mention whether you use winforms, wpf or asp.net, but there are various date and time pickers that support date and time pickers.

Answer 2

If you use two DateTime objects, one to save the date of the other, you can do the following:

 var date = new DateTime(2016,6,28); var time = new DateTime(1,1,1,13,13,13); var combinedDateTime = date.AddTicks(time.TimeOfDay.Ticks); 

An example of this can be found here.

Answer 3

Depending on how you format (and check!) The date entered in the text box, you can do this:

 TimeSpan time; if (TimeSpan.TryParse(textboxTime.Text, out time)) { // calendarDate is the DateTime value of the calendar control calendarDate = calendarDate.Add(time); } else { // notify user about wrong date format } 

Note that TimeSpan.TryParse expects the string to be in the format "hh: mm" (optional seconds).

Answer 4

Using https://github.com/FluentDateTime/FluentDateTime

 DateTime dateTime = DateTime.Now; DateTime combined = dateTime + 36.Hours(); Console.WriteLine(combined); 

Answer 5

Combine both. The date picker also supports pick time.

You just need to change the Format-Property and possibly the CustomFormat-Property.

Answer 6

  DateTime newDateTime = dtReceived.Value.Date.Add(TimeSpan.Parse(dtReceivedTime.Value.ToShortTimeString()));
