C# 使用C更新Google电子表格#

这是我第一次在这里发帖，我对谷歌API还不熟悉。我遇到的问题是，我试图登录到我的Google Drive帐户，并更新电子表格中的特定单元格。我可以登录到我的谷歌硬盘，但当我试图访问谷歌电子表格时，我得到了一个“解析失败”的错误

当我到达services.Query（Query）时，我得到了解析失败的错误。任何帮助都将不胜感激

下面是全部错误

有一个讨论“解析失败”问题的示例

它提到在Fiddler中看到一个失败的调用

---

尝试使用Fiddler，看看哪些调用可能会失败。

你能用堆栈跟踪发布完整错误吗？我也有同样的错误（解析失败）。你能解决它吗？你看到Fiddler或WireShark在电线上发生了什么吗？
