Question

我有一个员工班次的天数（工作日）列表如下：

List<int> workingDays = new List<int>();
workingDays.Add(1); // monday
workingDays.Add(2); // tuesday
workingDays.Add(3); // wednesday
workingDays.Add(5); // friday

这是员工的工作日。

现在，我需要在一个非工作日的选定月份中获得所有日子。

例如：

如果7月有31天，我应该得到以下列表：

July 3 // thursday is a non-working day
July 5 // saturday is a non-working day
July 6 // sunday is a nono-working day
July 10 // thursday is a non-working day

等等......

有关如何获取该列表的任何线索？

更新：

这是我的尝试：

for (int day = 1; day <= DateTime.DaysInMonth(currentDate.Year, currentDate.Month); day++) {
    DateTime dt = new DateTime(currentDate.Year, currentDate.Month, day);
    var shiftDay = shifts.Where(s => (int) dt.DayOfWeek - 1 == s.Day && s.IsActive).First();

    if (shiftDay == null) {

        // this is a non-working day because wasn't found in the shift List

    }
}

您应该使用DayOfWeek枚举而不是int来使代码更具可读性并且更不容易出错：

List<DayOfWeek> workingDays = new List<DayOfWeek>() { 
    DayOfWeek.Monday, DayOfWeek.Tuesday, DayOfWeek.Wednesday, DayOfWeek.Friday
};


var nonWorkingDays = Enumerable.Range(1, 31)
                               .Select(x => new DateTime(2014, 7, x))
                               .Where(d => !workingDays.Contains(d.DayOfWeek))
                               .ToList();

c＃根据班次获得一个月内的非工作日
