C# 如何防止google日历请求接收google联系人响应

多年来，我们通过c#客户端库（Google.API.Calendar.v3.1.9.2.1330）成功地使用了Google联系人和日历API。最近发生了一个不寻常的错误。日历API调用似乎得到了联系API响应（见下文）。以前有没有人遇到过这种情况，并且有办法防止这种情况再次发生

编辑： 包括代码段：

using Google.Apis.Calendar.v3;
using Google.Apis.Calendar.v3.Data;
using Google.Apis.Http;
using Google.Apis.Services;

...

var eventList = service.Events.List(calendarListEntry.Id);
eventList.TimeMin = dateFrom;
eventList.TimeMax = dateTo;
eventList.SingleEvents = true;
var events = eventList.Execute().Items;

---

编辑：这里有一个这样的例子。我从日志中提取了任何敏感信息，但事件的顺序是。1.我们看到两个成功的API请求和响应。2.我们得到一个404响应，但奇怪的是，它导致了一个解析异常，好像响应包含xml或至少以“您是否可以发布代码”开头的内容，看起来您试图混合xml和Json。Calendar V3返回JSon联系人API是一个旧的gdata API，返回xml。默认情况下，它们可能无法很好地配合。您好，DalmTo，是的，会引发异常，因为响应是属于另一个线程的json联系人响应，但不清楚日历api客户端调用为什么会收到该响应。我在问题中包含了异常发生的行（var events=eventList.Execute（）.Items；）。谢谢你的帮助，让我们来看看你的一些代码。这不会返回那个错误。我需要导致错误的代码。当前的google.net客户端库不与旧的gData api通信，它们是两个不同的系统。请输出calendarListEntry.IdImportGmailCalendarService.cs的值：第59行==“var events=eventList.Execute（）.Items；”
