What do you mean by "create appointment"? What is exactly the problem here? Are you asking how to add 20 minutes to a date/time?

create appointment means 'arrangement for meeting'..
I have,
from time: 10:00 am
to time: 2:00 pm

duration between meeting is 20 minutes
then 1st meeting time will be at 10:00 am, 2nd will be at 10:20 and so on..

now problem is how to create the time duration gap of 20 minutes by for loop or while loop

Solution 1

Try something like this:

C#

DateTime startTime = DateTime.Parse("10:00");
DateTime endTime = DateTime.Parse("14:00");
TimeSpan duration = new TimeSpan(0, 20, 0);
List<DateTime> appointments = new List<DateTime>();
while (startTime < endTime)
    {
    appointments.Add(startTime);
    startTime += duration;
    }

That builds a list of appointments at 20 minute intervals.
