Hello.

I would like to get number of working days in current month and year until today (C#).

e.g.: today is 12.5.2009 -->  8 working days
tomorrow it will be 13.5.2009 --> 9 working days


Thank you.

You need to count days without free ones, basic version:
- count all days without weekends, like:
DateTime theDateFrom;
DateTime theDateTo;
...
if(theDateFrom.DayOfWeek != DayOfWeek.Saturday && theDateFrom.DayOfWeek != DayOfWeek.Sunday)
   workdays++;
count till theDateFrom <= theDateTo

- however remember about bank holidays. Look for instance:

- finally, all depends on calendar. Saturday or Sunday could be a working day.

In http:Q_24377674.html I explained this process for VB, but that's the other way around (given the number of business days, how many "normal" days would that be?).

try again that link: http://Q_24377674.html

anyway, crystal_tower gave the same idea. Here's how I did it (full loop):
private int GetBusinessDays(DateTime dateFrom, DateTime dateTo)
{
    int countDays = 0;
    
    while (dateFrom < dateTo) {
        dateFrom = dateFrom.AddDays(1);
        DayOfWeek weekDay = dateFrom.DayOfWeek;
        if (weekDay != DayOfWeek.Saturday & weekDay != DayOfWeek.Sunday)  
        {
             countDays += 1;
        }
    }
    return countDays;
}

> I used abel s method.

nice and tx. You accidentally hit the "Accept and Award Point" of your own comment (which effectively makes your comment the solution, which it isn't), instead, I believe you wanted to assign points to me and crystal_tower. You can do so by clicking the "Accept Multiple Solutions". See screenshot for the difference between the two.

Note that the first one (the one in red) is only considered good if you found the solution yourself. Also see closing questions.
