Directory.Exists - UNC path with access denied c #

I am writing code to access directories and index found files. A user can enter a UNC path and impersonate another user to access this directory. I am using Directory.Exists to check if the path they entered is valid before trying to access it.

This works great for local paths, but when I try to access a UNC path that I know I don't have, Directory.Exists returns true.

My understanding is that Directory.Exists does not check if a particular path can only "access" that it exists or not.

What else can I use to check if a directory exists and I have access to it?

I don't know any of the filenames inside the directory at the moment.

Thank!

Why not just try to index by listing the files and handle the exception thrown when it can't access? There is always the possibility that a subfolder or an individual file may not be accessible anyway, even if you access the specified specific directory.

Interesting. I thought \ directory \. will not resolve, although the \ should be ok, but \ directory \. also good, which I think is a mistake, because I think "." the file is under the directory.

Take a look at the System.Security.AccessControl.DirectorySecurity class .
