C＃日期时间为加/减工作日 [英] c# DateTime to Add/Subtract Working Days

问题描述

我在这里给出一个日期方案（的DateTime ），该日期加/减 X 天（实现与 DateTime.AddDays ）必须加上或减去 X 工作日，即跳过周末和节假日。我怎样才能得到它这样做呢？我要实现自己的版本，并将其连接到一个日历或东西吗？

I have a scenario where given a date(DateTime),that date plus/minus x days(achieved with DateTime.AddDays) must add or subtract x working days, i.e., skip weekends and holidays. How can I get it to do this? Should I implement my own version and attach it to a calendar or something?

推荐答案

我会建议你必须自己实现它，并会做这样的扩展方法中：

I would suggest that you have to implement it by your own, and would do it inside an extension method like this:

public static class DateTimeExtensions
{
    public static DateTime AddWorkdays(this DateTime originalDate, int workDays)
    {
        DateTime tmpDate = originalDate;
        while (workDays > 0)
        {
            tmpDate = tmpDate.AddDays(1);
            if (tmpDate.DayOfWeek < DayOfWeek.Saturday && 
                tmpDate.DayOfWeek > DayOfWeek.Sunday &&
                !tmpDate.IsHoliday())
                workDays--;
        }
        return tmpDate;
    }

    public static bool IsHoliday(this DateTime originalDate)
    {
        // INSERT YOUR HOlIDAY-CODE HERE!
        return false;
    }
}
