I'm using a simple DirectoryInfo
to grab all directories on the root on the C drive. However, I'm running under administrator and i'm getting the error of path access denied, below is the code that I am running. How do I resolve the issue of path access?
DirectoryInfo Dinfo = new DirectoryInfo(@"C:\");
DirectoryInfo[] directories = Dinfo.GetDirectories("*.*", SearchOption.AllDirectories);
On newer versions of Windows C:\\Document and Settings
is a junction point , kind of a file system shortcut. It is not a normal directory, which means that it doesn't really work as a normal directory.
If you type in C:\\Document and Settings
in the start->run box you will also get an access denied error, so it is nothing specific to your program.
I'm a bit confused by how this works however. I thought that the junction point would be a transparent link to the new location which is c:\\users
but obviously not.
After looking at the duplicate question I'm less confused. The junction point really links to the new location which is c:\\users
. However, there is an explicit deny acl for reading on the junction point to prevent anyone from using it to read things:
C:>cacls "Documents and Settings" C:\\Documents and Settings Everyone:(DENY)(special access:)
FILE_READ_DATA Everyone:R NT AUTHORITY\\SYSTEM:F BUILTIN\\Administrators:F
C:>
If you are running as Administrator you might still run into
C:\\ Document and Settings是一个交接点,另外你无法访问系统卷信息目录。它放在C:\\ root上你必须捕获任何安全异常并跳过它来处理你的代码。
