.net DDay.iCal outlook与时区和重复模式的兼容性

我有幸让outlook通过电子邮件接受我的.ics文件，并将其解释为日历邀请，但我遇到了时区问题

最初，我发现如果我的所有日期都以UTC格式提供，Outlook会做正确的事情（正确的事情是在显示事件时将时间转换为系统的时区设置）。以下是iCalendar文件：

不幸的是，当我添加定期事件时，由于某些原因outlook不会这样做。因此，我尝试使用以下方法将时区添加到iCalendar文件中：

_calendar.AddTimeZone(myTimeZone);

奇怪的是，附件显示为“not supported calendar event.ics”，但是当我打开附件时，Outlook对文件的解释很好（大部分情况下）

以下是iCalendar文件：

有人知道outlook对此文件的哪个部分有问题吗？或者，也许更重要的是，是否有人知道我可以在dday.iCal中做些什么来让outlook开心

谢谢

首先，您必须使用TZID标识符，以便日历知道事件是哪个时区，而不是日历

这将导致更改您的DTSTART

发件人：

致：

然后，您还应该将时区定义（尤其是RRULE、DTSTART）更改为：

致：

`

谢谢。第一个问题很容易解决。我最大的问题是，使用dday.ical库时，我无法使我的时区定义与提供的时区定义相同。你有使用这个库的经验吗？时区定义更像是一种奖励，关键是要在dtstart中指定tzid。
