推荐答案

我今天遇到了这个问题，最后找到了它.

I ran into this one today and finally tracked it down.

该异常试图告诉您，当DirectoryInfo将路径作为参数(例如，CreateSubdirectory或GetFiles)时，如果path参数包含Root并抛出此难以捉摸的异常，它将拒绝.

The exception is trying to tell you that when a DirectoryInfo takes a path as an argument (e.g., CreateSubdirectory or GetFiles), it will object if the path argument contains the Root and throw this elusive exception.

因此包含"C:\"或"D:\"等的路径参数不起作用.有了这种上下文，异常消息实际上就有意义了.

So path arguments that contain "C:\" or "D:\" etc do not work. Armed with this context, the exception message actually makes a bit of sense.

在您的代码中，您使用的是FullName属性，并且此字符串包含"C:\"或任何根.

In your code, you were using the FullName property and this string contains "C:\" or whatever the root is.

鉴于这个问题的年龄，我应该添加c#、. NET 4.5，VS2013.

Given the age of the question, I should add c#, .NET 4.5, VS2013.
