我想将正确的小时数绑定到正确的工作时间。工作周是从周一到周日。根据当天的时间，工作有不同的价格。基于完成当天时间的工作价格称为期间。我们使用24小时时间格式。
示例：
期间如下所示：
public class Period
{
public Period()
{
}
public string Name { get; set; }
public int Days { get; set; }
public bool Holiday { get; set; }
public TimeSpan Start { get; set; }
public TimeSpan End { get; set; }
}
Days是int，但值将来自此枚举：
[Flags]
public enum Workweek
{
Sunday = 1,
Monday = 2,
Tuesday = 4,
Wednesday = 8,
Thursday = 16,
Friday = 32,
Saturday = 64
}
当期间Days属性为62时，表示期间从星期一到星期五有效，此时天数为：65期间为星期六至星期日。当天数为：6时，周期为周一至周二。
Holiday为真时表示期间仅在假日有效。假日超过正常的一天或周末。
工作班次如下所示：
public class Work
{
public Work()
{
}
public string Name { get; set; }
public DateTime Start { get; set; }
public DateTime End { get; set; }
}
假设我有一个List<Work>和一个List<Period>，我如何将工作时间绑定到正确的时间段？每个期间都有不同的定价。
示例：
案例1：如果你在星期一的工作班次：15：00到23:00之间，那么工作班次将是这样的：
案例1.1：如果特定星期一是假日，那么它将是：
案例2：如果相反，工作从星期一的20:00开始，到第二天的04:00结束，结果将是：
案例2.2：如果星期一是假日，那将是：
假期日为List<DateTime>。
我如何将小时数与正确的时期相匹配？
到目前为止我尝试了什么：
Work work = new Work()
{
Name = Demo,
Star = new DateTime(2017,05,02,15,00,00);
End = new DateTime(2017,05,02,23,00,00);
};
List<Period> periods = new List<Period>();
foreach (var period in periods)
{
Workweek shiftDay = (Workweek)Enum.Parse(typeof(Workweek), work.Start.DayOfWeek, true); // i think this is wrong, because in the case where the end date is in the next day
Workweek periodDay = (Workweek)period.Days;
if ((shiftDay & periodDay) == shiftDay)
{
// the work matches the period
}
}
我想我应该使用foreach并在开始日期和结束日期之间循环每一秒，并检查第二天是否与期间日相匹配。
这样的事情：
public static IEnumerable<DateTime> EachSecond(this Work work)
{
DateTime currentSecond = new DateTime(work.Start.Year, work.Start.Month, work.Start.Day, work.Start.Hour, work.Start.Minute, work.Start.Second, work.Start.Millisecond);
while (currentSecond <= wor.kEnd)
{
yield return currentSecond;
currentSecond = currentSecond.AddSeconds(1);
}
}
Work work = new Work()
{
Name = Demo,
Star = new DateTime(2017,05,02,15,00,00);
End = new DateTime(2017,05,02,23,00,00);
};
List<Period> periods = new List<Period>();
foreach (var second in work.EachSecond())
{
Workweek shiftSecond = (Workweek)Enum.Parse(typeof(Workweek), second.DayOfWeek, true);
foreach (var period in periods)
{
Workweek periodDay = (Workweek)period.Days;
if ((shiftSecond & periodDay) == shiftSecond)
{
}
}
}

尝试这样的事情。我不知道为什么你需要一个自定义的工作周，当你可以使用标准的DayOfWeek。无论如何，我跟着你的请求。
