推荐答案

目前尚不清楚您想要什么.
但是，如果我猜对了，您想计算一个月中的工作日(工作日).您可以使用 System.DateTime.DayOfWeek [ http://stackoverflow.com/questions/1820173/calculate-the-number-of-weekdays-between-two-dates-in-c-sharp [ http://stackoverflow.com/questions/4022993/how-to-get-a-list-of-week-days-in-a-month [

It is unclear what you want.
But if I guess correctly, you want to calculate weekdays (workdays) in a month. You can use System.DateTime.DayOfWeek[^] property to see what day of week is a specific date.
Here you have some methods: http://stackoverflow.com/questions/1820173/calculate-the-number-of-weekdays-between-two-dates-in-c-sharp[^], you just have to change them to take only Sunday as weekend, and Saturday as weekday/workday.

Update: here i found the most elegant one: http://stackoverflow.com/questions/4022993/how-to-get-a-list-of-week-days-in-a-month[^]. With a little adaptation:

public static int GetWorkdays(int year, int month)
        {
            return Enumerable.Range(1, DateTime.DaysInMonth(year, month))
                             .Select(day => new DateTime(year, month, day))
                             .Where(dt => dt.DayOfWeek != DayOfWeek.Sunday)
                             .Count();
        }
}
