Question

I’m trying to loop through EACH DAYof the WEEK between 2 time periods

  DateTime start = new DateTime(2010, 1, 1);
  DateTime end = new DateTime(2011, 12, 12);

I have managed to get the number of days between these dates using the following code

     TimeSpan range = (end - start);

turn out to be 710.

I am now looking to get for each month the DAYs OF THE WEEK,

FOR instance

Jan
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 171 18 19 20 . . .

with the matching

M T W T F S S M T W T F S S M

I understand c# has a property from DateTime class DayOfWeek which gets the day of the week
my problem is constructing a loop to do the above?

anyone?

Answer 1

This will loop through all days from the start date to the end date and get the day of week for each.

DateTime startDate = new DateTime(2010, 1, 1);
DateTime endDate = new DateTime(2011, 12, 12);
for (DateTime date = startDate; date <= endDate; date = date.AddDays(1))
{
    DayOfWeek dw = date.DayOfWeek;
    // ...
}

Unless you’re really worried about optimization, I wouldn’t spring for anything more complicated.
