For example, I will be given a time on hours with type DateTime hours like this
and every time 30 minutes I like to input the value into a List<DateTime>
so, how can I get the value to put into a list that is look like this?
My Code
DateTime starTime = new DateTime();
DateTime endTimes = new DateTime();
DateTime interval = new DateTime();
List<DateTime> intervals = new List<DateTime>();
starTime = DateTime.ParseExact(fulldate + "00:00",
"yyyy/MM/dd HH:mm",
CultureInfo.InvariantCulture);
endTimes = DateTime.ParseExact(fulldate + "02:00",
"yyyy/MM/dd HH:mm",
CultureInfo.InvariantCulture); ;
interval = starTime;
for (int i = 0; i < 24; i++)
{
interval.AddHours(0.5);
intervals.Add(interval);
if (interval.ToString("HH:mm") == endTimes.ToString("HH:mm"))
{
break;
}
}
Can anyone help me to solve this?
With some assumption (that end time is on the same day, that your end time is always something that can be devided by 30 mins, ...) this would work.
var start = new TimeSpan(0, 0, 0);
var end = new TimeSpan(2, 0, 0);
var current = start;
List<DateTime> values = new List<DateTime>();
var startDate = DateTime.Now.Date; // editited after @pinkflowydx33's comment
values.Add(startDate + start);
while (current < end)
{
current = current.Add(new TimeSpan(0, 30, 0));
values.Add(startDate + current);
}
foreach (var v in values)
{
Console.WriteLine(v);
}
i prepared that type of solution. - It's loop over number, which represent - times of valueToChange - in this specific case between 30 minutes - and add to the startDate - 30 minutes and also saving to list.
using System;
public class Program
{
public static void Main()
{
List<DateTime> intervals = new List<DateTime>();
var changeValue = 30;
var startDate = new DateTime(2010, 05, 12, 13, 00, 00);
var endDate = new DateTime(2010, 05, 12, 14, 00, 00);
var timeIntervals = System.Math.Abs(startDate.Subtract(endDate).TotalMinutes / changeValue);
for (int i = 0; i < timeIntervals; i++)
{
startDate.AddMinutes(30);
intervals.Add(startDate)
}
}
}
In this case the start and end date are divided by 30 minutes without rest - so if there will be 13:00 and 13:12 - it's doesn't add the value to List - cause the value doesn't > 30.
