Question

我有这个功能

 private static void DeleteEvent(CalendarService service, string pTitle,DateTime pDate)
    {
        FeedQuery query = new FeedQuery();
        query.Uri = new Uri("http://www.google.com/calendar/feeds/default/private/full");
        AtomFeed calFeed = service.Query(query);
        foreach (AtomEntry entry in calFeed.Entries)
        {
            if (pTitle.Equals(entry.Title.Text))
            {
                entry.Delete(); break;
            }
        }
    }

我如何按标题和日期删除活动？

这些可能会有所帮助：

http://code.google.com/apis/calendar/data/2.0/developers_guide_dotnet.html#RetrievingEvents

我猜想以下内容可能会起作用：

EventQuery query = new EventQuery("https://www.google.com/calendar/feeds/default/private/full");  
query.StartDate = ...;
query.EndDate = ...;
EventFeed feed = service.Query(query);
foreach (var entry in feed.Entries)
{
    if (pTitle.Equals(entry.Title.Text))
    {
        entry.Delete(); break;
    }
}

虽然上述解决方案可行，但我建议采用另一种方法。不是每次都遍历所有事件而是删除（如果找到），为什么不让Google为您找到特定事件。可以使用ExtendedProperty使用以下方法

来完成

为您添加的每个事件分配一个ID（与您在数据库中设置的相同）。
删除时，您传递要删除的ID并使用“查询”为您提取
删除特定活动

Google.GData.Calendar.EventEntry Entry = new Google.GData.Calendar.EventEntry();

//create the ExtendedProperty and add the EventID in the new event object, 
//so it can be deleted / updated later
ExtendedProperty oExtendedProperty = new ExtendedProperty();
oExtendedProperty.Name = "EventID";
oExtendedProperty.Value = GoogleAppointmentObj.EventID;
Entry.ExtensionElements.Add(oExtendedProperty);

string ThisFeedUri = "http://www.google.com/calendar/feeds/" + CalendarID 
+ "/private/full";
Uri postUri = new Uri(ThisFeedUri);

//create an event query object and attach the EventID to it in Extraparameters
EventQuery Query = new EventQuery(ThisFeedUri);
Query.ExtraParameters = "extq=[EventID:" + GoogleAppointmentObj.EventID + "]";
Query.Uri = postUri;

//Find the event with the specific ID
EventFeed calFeed = CalService.Query(Query);

//if search contains result then delete
if (calFeed != null && calFeed.Entries.Count > 0)
{
   foreach (EventEntry SearchedEntry in calFeed.Entries)
   {
      SearchedEntry.Delete();
      break;
   }

}
