Getting all DateTimes between two 'DateTime's in C#
I have two DateTime
s, and I want to get all DateTime
s between these Dates. Such as, if my Dates are like 01.01.2010 - 05.01.2010, my function should return me a list of date (List), and it must contain 01.01.2010, 02.01.2010, 03.01.2010, 04.01.2010, and 05.01.2010.
I wrote a function like this. It works fine, if my dates are in a month. It won't work if my dates are like 01.01.2010 - 05.02.2010. Because the month changed, and my function can't handle it. Is there a function in C# that returns all dates between two dates? Or how can I handle month change?
public void GetAllDatesAndInitializeTickets(DateTime startingDate, DateTime endingDate)
{
List<DateTime> allDates = new List<DateTime>();
int starting = startingDate.Day;
int ending = endingDate.Day;
for (int i = starting; i <= ending; i++)
{
allDates.Add(new DateTime(startingDate.Year, startingDate.Month, i));
}
Question solved, see Tim Robinson's simple answer to use.
You can use DateTime
objects directly in the loop, in place of your int
. DateTime.AddDays
handles month ends correctly.
for (DateTime date = startingDate; date <= endingDate; date = date.AddDays(1))
allDates.Add(date);
How about something like this?
public IEnumerable<DateTime> DateRange(DateTime fromDate, DateTime toDate)
{
return Enumerable.Range(0, toDate.Subtract(fromDate).Days + 1)
.Select(d => fromDate.AddDays(d));
}
Edit: Tested now. :)
public IEnumerable<DateTime> GetAllDatesAndInitializeTickets(DateTime startingDate, DateTime endingDate)
{
if (endingDate < startingDate)
{
throw new ArgumentException("endingDate should be after startingDate");
}
var ts = endingDate - startingDate;
for (int i = 0; i < ts.TotalDays; i++)
{
yield return startingDate.AddDays(i);
}
}
