skipping access denied folders when using GetDirectories()

lane0p2

Hi all, i can use something like the code below to get all the directory within a given folder. DirectoryInfo di = new DirectoryInfo(@"C:\"); foreach (DirectoryInfo d in di.GetDirectories("*.*", SearchOption.AllDirectories)) { Console.WriteLine(d.Name); } but as soon as i hit a folder i dont have access to it crashes. is there anyway i can perform the same action but get it to skip folder i don't have access too? Many Thanks, Phil

use a try/catch?

Help me! I'm turning into a grapefruit! Buzzwords!

use try-catch inside the loop. That is what I do. BTW: .NET 4.0 will offer better methods to enumerate files/folders, without requiring a (possibly huge) array, so one will be able to really use the recursive mode. :)

AFAIK there is no such option present. You will have to write your own method to do this.

That will not work. The exception will occur while executing the GetDirectories method itself and control will never go inside the try/catch.

:confused: It works for me, I am listing all files/folders of any device I choose (both XP and Vista). If GetDirectories() and GetFiles() would not cope with inaccessible files and folders, they would be completely useless, wouldn't they? :)

In XP SP2, I created a folder(c:\TestFolder) and "denied" all the permissions under security tab. GetDirectories method itself will throw exception. Control never came to try/catch. See my code:

  DirectoryInfo dirInfo = new DirectoryInfo(@"C:\\");
  foreach (DirectoryInfo dir in dirInfo.GetDirectories("\*.\*", SearchOption.AllDirectories)) {
    try {
    }
    catch {
    }
  }

That is new to me. I'll have to investigate. And what is your solution? :)

Never faced this issue, so far. If I do, I would go for Linq. May be something along the lines of this[^] approach. If it .Net 2.0, Linq bridge[^] might save me.
