asp.net - aspアプリケーションからGoogleカレンダーイベントを更新する方法は?

Question

イベントの主キーを Google カレンダーに挿入し、そのイベントを更新する EventQuery 呼び出しの後に取得したい

Evententry クラスで、主キーを割り当て、後でそのイベントを更新するために取得するプロパティが見つかりませんでした。

以下のアプローチを使用して ExtendedProperty を使用することで実行できます

1.Assign an ID (same as you set in your DB) to each event you add through
  ExtendedProperty . 
2.When updating / deleting you pass the ID and use Query to fetch it for you
3.If the event is found you can delete / update the specific event

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();
      //To update comment the code above and uncomment the code below 
      //CalService.Update(SearchedEntry);
      break;
   }
}
else
{
    InsertedEntry = CalService.Insert(postUri, Entry);
}
