Working on an OOB app.

dynamic fileSystem = AutomationFactory.CreateObject("Scripting.FileSystemObject");
dynamic drives = fileSystem.Drives;

foreach (var drive in drives)
{
DriveCollection.Add(new Drive{
                    VolumeName = drive.VolumeName,
                    DriveLetter = drive.DriveLetter,
                    TotalSpace = drive.TotalSize,
                    FreeSpace = drive.FreeSpace
                    });
listBox.Items.Add(string.Format("{0}  {1}", drive.DriveLetter, drive.VolumeName));
}

When run in the debugger, 'C' drive is enumerated, then an exception is thrown:

"Exception from HRESULT: 0x800A0047"
When I run the app from the desktop, no drives are enumerated before the exception is thrown.

Any hints on how to protect against this exception? Somehow checking the validity of the 'drive' object before referencing it in the Drive constructor?

I Think You Have Permission Issue!!! – Jignesh.Raj Apr 04 '13 at 03:40
Is your app using Elevated Trust? – jv42 Apr 04 '13 at 13:15
Yes, it is using elevated trust. It's confusing that 'C' is enumerated before the exception is thrown... – Number8 Apr 04 '13 at 17:05
