嗨，我有这个ical（1.0 beta）

我有这个代码

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）导入谷歌日历

如您所见，我有 RRULE:FREQ=DAILY;UNTIL=20110604，但我的代码永远不会选择它。直到总是像默认日期时间一样。

有人有想法么？

谢谢

这是当前版本的 dday ical 中的一个错误，将在以后的版本中修复
