错误很清楚：路径您尝试使用..来尝试访问位于顶级或根文件夹之上的文件夹。
可能，这意味着您创建了一个类似C：的路径\..\ myfolder或类似的，但由于我们看不到您的代码，我们无法告诉您该如何解决它。
所以使用调试器，并仔细检查您尝试使用的路径 - 然后开始寻找它的原因。但我们不能为你做任何事情！
The error is pretty clear: the path you at trying to use is using ".." to try and access a folder which is above the top-level - or root - folder.
Probably, that means you created a path like "C:\..\myfolder" or similar, but since we can't see your code we can't tell you what to do to fix it.
So use the debugger, and examine the path you are trying to use carefully - then start looking for why it is like that. But we can't do any of that for you!
