推荐答案

你几乎不能在没有访问违规的情况下在根文件夹上使用AllDirectories - 除非你拥有完全的管理员权限，这对于简单的文件搜索来说相当过分！



你唯一的选择就是在try中使用递归文件夹检查... catch块，并单独检查驱动器上的每个文件夹，然后查看其子文件夹，前提是您可以访问它们。

You can't use AllDirectories on the root folder without almost certainly getting access violations - unless you have full admin privileges, which is rather overkill for a simple file search!

Your only option is to use a recursive folder check inside a try...catch block, and check each folder on the drive individually, followed by its subfolders provided you have access to them.
