D365 - C#计算两个时间点之间的节假日和调休

其中调休配置在了new_holidayconfig这张表，表里还有国家和日期字段，如果不是D365可以用其他办法去存。

public static int WorkingDayCount(DateTime startTime, DateTime endTime, string countryId, IOrganizationService adminOrganizationService)
        {
            int workingDay=0;
            int totalDays = (int)(endTime-startTime).TotalDays;

            {
                if(startTime.AddDays(i).DayOfWeek!=DayOfWeek.Saturday && startTime.AddDays(i).DayOfWeek != DayOfWeek.Sunday)
                {
                    workingDay++;
                }
            }
            if (string.IsNullOrWhiteSpace(countryId))
                return workingDay;
