ExecuteQuery停止为Sharepoint ClientContext工作

大约一周前用于将文件上载到我们的Sharepoint网站的代码正在工作。突然它不是，当我运行ClientContext ExecuteQuery（）方法时，我得到以下错误：ExecuteQuery停止为Sharepoint ClientContext工作

'='是一个意外的标记。预期的标记是';'。

这里是我的代码：

using (var context = new ClientContext(siteUrl)) 
     { 
      context.Credentials = GetSharePointCredentials(); 
      var web = context.Web; 
      Microsoft.SharePoint.Client.List list = context.Web.Lists.GetByTitle("Account"); 
      context.ExecuteQuery();

没有什么花哨的事情。我真的不知道从哪里开始。什么也没有变。代码没有改变。我在Visual Studio中处于调试模式，但（a）它也不适用于那些在生产中使用该软件的人员，以及（b）在调试时我确实已经使其一次工作，所以这是一个间歇性的事情（如果失败99％时间可以称为间歇性的）。

如果有帮助，我们将在云中托管Sharepoint。

这里是堆栈跟踪：

请提供一个堆栈跟踪？ – 12seconds

在上面添加了它。这是一些XML错误，第1行107.但是，XML是什么？ – gareth99

如何将文件保存到SharePoint？该错误指出XML中存在非法字符，最有可能是＆并且需要编码为&s; – 12seconds
