获取工作日DateTime两个日期的列表 [英] Get working days DateTime List of two dates

问题描述

我正在尝试获取两个日期之间的工作日列表，但我只是一个月而已。

Im trying to get a List of working days between two dates but I got just from a month.

var workingDays = Enumerable.Range(1, daysInMonth)
                          .Where(d =>
                              !weekends.Contains(new DateTime(last30Days.Year, last30Days.Month, d).DayOfWeek)).ToList();

但是这样一来，我只有一个特定的月份。

But this way i get just one speciefic month.

推荐答案

从函数开始，获取两个日期之间的所有天数：

Start out with a function to get all days between two dates:

public static IEnumerable<DateTime> DaysBetween(DateTime start, DateTime end)
{
    var current = start;
    if (current != current.Date) //handle the case where the date isn't already midnight
        current = current.AddDays(1).Date;
    while (current < end)
    {
        yield return current;
        current = current.AddDays(1);
    }
}

然后只过滤掉非工作日：

Then just filter out the non-working days:

public static IEnumerable<DateTime> WorkDayBetween(DateTime start, DateTime end)
{
    return DaysBetween(start, end)
        .Where(date => IsWorkDay(date));
}

//feel free to use alternate logic here, or to account for holidays, etc.
private static bool IsWorksDay(DateTime date)
{
    return date.DayOfWeek != DayOfWeek.Saturday
                    && date.DayOfWeek != DayOfWeek.Sunday;
}
