使用Nodatime排除期间的日期(Excluding dates from period using Nodatime)

 我正在尝试研究两个LocalDateTime值之间的时间量并排除特定日期（在本例中，它是银行假日）。 
 
var bankHolidays = new[] { new LocalDate(2013, 12, 25), new LocalDate(2013, 12, 26) };
var localDateTime1 = new LocalDateTime(2013, 11, 18, 10, 30);
var localDateTime2 = new LocalDateTime(2013, 12, 29, 10, 15);

var differenceBetween = Period.Between(localDateTime1, localDateTime2, PeriodUnits.Days | PeriodUnits.HourMinuteSecond);
 
 differenceBetween值显示两个日期之间的天数/小时/分钟/秒，正如您所期望的那样。 
 
 我可以从开始日期检查每一天，看看bankHolidays集合是否包含该日期，例如 
 
var bankHolidays = new[] { new LocalDate(2013, 12, 25), new LocalDate(2013, 12, 26) };
var localDateTime1 = new LocalDateTime(2013, 11, 18, 10, 30);
var localDateTime2 = new LocalDateTime(2013, 12, 29, 10, 15);

var differenceBetween = Period.Between(localDateTime1, localDateTime2, PeriodUnits.Days | PeriodUnits.HourMinuteSecond);

var london = DateTimeZoneProviders.Tzdb["Europe/London"];

for (var i = 1; i < differenceBetween.Days; ++i)
{
    var x = localDateTime1.InZoneStrictly(london) + Duration.FromStandardDays(i);

    if (bankHolidays.Any(date => date == x.Date))
    {
        //subtract one day for the period.
    }
}
 
 我觉得我错过了一些明显的，应该有一个更简单的方法，是否有更简单的方法来找到两个日期之间的时间段，但不包括某些日期？ 
 
 我也需要在这个例外中包括周末，显而易见的方法似乎是在检查银行假期时检查周末的一周，这似乎不是处理它的最佳/正确方法。 

I'm trying to workout the amount of time between two LocalDateTime values and exclude specific dates (in this example, it's bank holidays).
 
var bankHolidays = new[] { new LocalDate(2013, 12, 25), new LocalDate(2013, 12, 26) };
var localDateTime1 = new LocalDateTime(2013, 11, 18, 10, 30);
var localDateTime2 = new LocalDateTime(2013, 12, 29, 10, 15);

var differenceBetween = Period.Between(localDateTime1, localDateTime2, PeriodUnits.Days | PeriodUnits.HourMinuteSecond);
 
The differenceBetween value shows the number of days/hours/minutes/seconds between the two dates, as you would expect. 
 
I could check every single day from the start date and see if the bankHolidays collection contains that date e.g.
 
var bankHolidays = new[] { new LocalDate(2013, 12, 25), new LocalDate(2013, 12, 26) };
var localDateTime1 = new LocalDateTime(2013, 11, 18, 10, 30);
var localDateTime2 = new LocalDateTime(2013, 12, 29, 10, 15);

var differenceBetween = Period.Between(localDateTime1, localDateTime2, PeriodUnits.Days | PeriodUnits.HourMinuteSecond);

var london = DateTimeZoneProviders.Tzdb["Europe/London"];

for (var i = 1; i < differenceBetween.Days; ++i)
{
    var x = localDateTime1.InZoneStrictly(london) + Duration.FromStandardDays(i);

    if (bankHolidays.Any(date => date == x.Date))
    {
        //subtract one day for the period.
    }
}
 
I feel like I'm missing some obvious and there should be an easier method, is there a simpler way to find a period between two dates whilst excluding certain dates?
 
I also need to include weekends in this exclusion too, the obvious way seems to be to check the day of the week for weekends whilst checking bank holidays, this just doesn't seem like the best/correct way of handling it though.
