谷歌日历 api 不返回经常性事件

Question

I'm trying to pull a list of events from my Google Calendar based on a date range, most of which are recurring events. The following code returns events that were entered during the date range, but not recurrences that happen during that date range. Any idea what I'm doing wrong?

EventQuery eventQuery = new EventQuery(calendarUri);
eventQuery.SingleEvents = true;
eventQuery.StartDate = startDate;
eventQuery.EndDate = endDate;
EventFeed resultsFeed = calendarService.Query(eventQuery);

Be aware that Query returns only 25 Entries + NextChunk is there are more. You need to Query again on the NextChunk.

EventFeed calFeed = service.Query(query) as EventFeed;

// now populate the calendar
while (calFeed != null && calFeed.Entries.Count > 0)
{
    // look for the one with dinner time...
    foreach (EventEntry entry in calFeed.Entries)
    {
        this.entryList.Add(entry); 
        if (entry.Times.Count > 0)
        {
            foreach (When w in entry.Times) 
            {
                dates.Add(w.StartTime); 
            }
        }
    }
    // just query the same query again.
    if (calFeed.NextChunk != null)
    {
        query.Uri = new Uri(calFeed.NextChunk); 
        calFeed = service.Query(query) as EventFeed;
    }
    else
        calFeed = null;
}

Further: When contains an Number of entries on recurring events. Need to look for the right one.
