问题描述

大家好.....

我想搜索目录中的所有子目录
我的代码是

Hi Everyone.....

I want to search all sub directory within a directory
my code is

DirectoryInfo di = new DirectoryInfo(Search_Path);
DirectoryInfo[] direcorries = di.GetDirectories("*.*", SearchOption.AllDirectories);

但是这里我有一个例外

but here i got an exception

exception {"Access to the path 'F:\\System Volume Information\\' is denied."}	System.Exception {System.UnauthorizedAccessException}

但是如果我用

but if i used

DirectoryInfo di = new DirectoryInfo(dir);
DirectoryInfo[] direcorries = di.GetDirectories("*.*", SearchOption.TopDirectoryOnly);

那么它不会通过异常....

为什么会这样?

我想避免使用此系统卷信息"文件夹.我该怎么做??

then it does not through an exception ....

why this happens?

I want to avoid this System Volume Information folder. How can i do that ??

推荐答案

AFAIK，使用任何直接选项都很难通过代码跳过它们.我寻找了类似的东西(如果之前已经讨论过)，并通过SA找到了以下答案:

AFAIK, it would be difficult to skip them through code using any direct option. I looked for something similar if already discussed earlier and found this answer by SA: How to display accessible files only and skip inaccessible file?[^]

It looks like, you don''t have a direct way to go through all skipping inaccessible folders by any setting. You need to handle those specific errors in a try-catch and move on. Not a good way but looks like the possible way to get you seek.
