DirectoryInfo.GetFiles() Access Denied errors (C#)

[RodneyAnonymous]

Hello everyone. I'm working on a simple utility that lists all files in a given directory with a given extension and outputs the results to a text file. I'm encountering issues while testing where the DirectoryInfo.GetFiles returns nothing. When I put a break in and check it out further, it looks like I'm getting ERROR_ACCESS_DENIED when the GetFiles hits certain directories (for example, a System Volume Information directory).

If this were VB I'd just be sloppy and throw an Error Resume Next, lolling all the way to the bank, but obviously I don't have that option in C#. The problem is that using try/catch isn't returning any Exceptions, so I don't know what else to do. Can anyone suggest how I can handle this?

Heres's the code I'm using:

private void searchFiles(string drive, string extension, string savedFile)
{
            FileInfo saveList = new FileInfo(savedFile);
            StreamWriter w = saveList.CreateText();
            DirectoryInfo di = new DirectoryInfo(drive);
            FileInfo[] lstFiles = di.GetFiles(extension, SearchOption.AllDirectories);
 
            foreach (FileInfo fi in lstFiles)
            {
                w.WriteLine(fi.FullName);
            }
            w.Close();
}

I believe you can supply permisions to directory/file accesses so that you avoid the "error".

It only returns an empty set for directories you are "not allowed" right, and not the entire thing? so is that really a problem?

Its easy... Use the code below from VB.Net:

Dim d As New DirectoryInfo(path)
 
For Each Directory As DirectoryInfo In d.GetDirectories()
    If (Directory.Attributes And FileAttributes.System) <> FileAttributes.System Then
        'Your code here!
    End If
Next
