Azure虚拟机试图模拟和访问文件

Question

这是我的界面。我在Azure虚拟机中有2个用户，第一个是“管理员”，另一个是“用户”。我的“用户”无权访问我的文件C：/direc/test.txt，但我的“管理员”拥有所有权限。

因此，我试图以管理员身份模拟，因此我可以以“用户”身份访问C：/direc/test.txt。

但是，它给了我这个疯狂的错误：
：

  

表达式：[mscorlib递归资源查找错误]
  说明：mscorlib中资源查找期间的无限递归。
  这可能是mscorlib中的错误，也可能是某些可扩展性中的错误，例如程序集解析事件或CultureInfo名称。资源名称：UnknownError_Num

这是我班上的假人

                }
