Adding Hour to datetime...

[nick3]

Hello, Im using a MonthCalender to get a dateTime, and just a textbox to let the user enter hours and minutes, so now I just want to add this so say the user enters 10:20 then I would like it to be (for example) 1999-10-10 10:20:00 instead of 1999-10-10 00:00:00, so I tryed to convert the string 10 to a double and the string 20 to an other double and trying to use dateTime.addhour(hours); But this wont work, the datetime is still 1999-10-10 00:00:00... I dont have my code on this computer, if you dont get what I mean i can post it, but we can start with this

Here is the code now too!!

            DateTime dtStart, dtEnd;
            TimeSpan startHour, startMin, endHour, endMin;
            dtStart = this.mcStartDate.SelectionStart;
            dtEnd = this.mcEndDate.SelectionStart;
            startHour = TimeSpan.FromHours(Convert.ToDouble(this.mtbStartTime.Text.Substring(0,2)));
            dtStart = dtStart.Add(startHour);

startHour is 10:00:00 if you enter 10 hours, but i still get 1999-10-10 00:00:00

DateTime object is not mutable. When you use AddHours() method it returns new DateTime object.

using System;

namespace ConsoleApplication1
{
	class Program
	{
		static void Main()
		{
			var date = DateTime.Today;
			date = date.AddHours(10);
			Console.WriteLine(date);

			Console.ReadLine();
		}
	}
}
