C＃删除谷歌日历事件

Question

我在尝试使用Google Calendar API删除事件时得到了一个GoogleApiExeption。设置：

public GoogleCalendarManager() //Setup tokens and stuff
    {
        using (var stream =
            new FileStream("credentials.json", FileMode.Open, FileAccess.Read))
        {
            // The file token.json stores the user's access and refresh tokens, and is created
            // automatically when the authorization flow completes for the first time.
            string credPath = "token.json";
            credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
                GoogleClientSecrets.Load(stream).Secrets,
                Scopes,
                "user",
                CancellationToken.None,
                new FileDataStore(credPath, true)).Result;
            Console.WriteLine("Credential file saved to: " + credPath);
        }

        // Create Google Calendar API service.
        service = new CalendarService(new BaseClientService.Initializer()
        {
            HttpClientInitializer = credential,
            ApplicationName = ApplicationName,
        });
    }

删除功能：

public void deleteGoogleTask(Event newEvent)
    {
        service.Events.Delete("primary", newEvent.Id).Execute();
    }

最后一行抛出异常。设置部分可用于接收日历事件。 newEvent id与Google文档中的“ Try this Api”一起使用，因此我认为设置部分存在问题。 感谢您的帮助。
