您好我有这个ical (1.0 beta)d日iCal和谷歌日历，直到问题
我有这样的代码
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;
}
我导入（iCal格式）

谷歌日历，你可以看到我有RRULE:FREQ=DAILY;UNTIL=20110604，但我的代码从来没有拿起规则。直到总是像默认的日期时间。
任何人有任何想法？
