示例1: GetDayOfYearHelper
private static int GetDayOfYearHelper(Calendar calendar, DateTime time, CalendarWeekRule rule, DayOfWeek firstDayOfWeek)
{
int weekOfYear = calendar.GetWeekOfYear(time, rule, firstDayOfWeek);
int dayOfYear = calendar.GetDayOfYear(time); // 1-based
int dayOfWeek = calendar.GetDayOfWeek(time) - firstDayOfWeek + 1; // 1-based
if (dayOfWeek <= 0)
dayOfWeek += DaysPerWeek; // Make it a positive value
int dayOfWeekForJan1 = dayOfWeek - (dayOfYear - 1) % DaysPerWeek; // 1-based
if (dayOfWeekForJan1 <= 0)
dayOfWeekForJan1 += DaysPerWeek; // Make it a positive value
// When the day of specific time falls on the previous year,
// return the number of days from January 1 directly.
// There could be 6 weeks within a month.
