Question

我有这段代码

IICalendarCollection iCal = iCalendar.LoadFromStream(fileStream); 
foreach (var ic in iCal) 
{ 
    foreach (var evt in ic.Events)
    { 
        DateTime now = DateTime.UtcNow.Date; 
        if (evt.Start.UTC.Date.CompareTo(now) >= 0 && evt.End.UTC.Date.CompareTo(now) >= 0) 
        { 
            foreach (var rule in evt.RecurrenceRules) 
            { 
                if (rule.Frequency == FrequencyType.Daily) 
                { 
                    // always false until is never set. 
                    bool doesRepeatingEnd = DoesRepeatingEnd(rule); 
                    if (doesRepeatingEnd) 
                    {
                        TimeSpan until = now.Subtract(rule.Until); 
                        int days = until.Days; 
                    } 
                    else { }    
                } else if (rule.Frequency == FrequencyType.Weekly) 
                { 
                } 
                else if (rule.Frequency == FrequencyType.Monthly) 
                { 
                } 
                else if (rule.Frequency == FrequencyType.Yearly) 
                { 
                }

            } 
    }   } 
}


        private static bool DoesRepeatingEnd(IRecurrencePattern rule) 
        { 
            DateTime until = rule.Until; 
            return until != DateTime.MinValue; 
        }

我以（ical格式）

正如您所看到的，我有RRULE:FREQ=DAILY;UNTIL=20110604，但我的代码从未接受过规则。直到最后仍然是默认的日期时间。

有人有什么想法吗？

谢谢
