VB.NET: GetFiles Method - "Access to the path 'G:\System Volume Information' is denied."

Here is my code,

Dim allFiles As FileInfo() = 
                        tempDir.GetFiles("*.pdf", SearchOption.AllDirectories)

I've googled and found that I need to change the permissions of my app from Project properties > View UAC Settings > and change level to level="requireAdministrator"

But its also not working. I found something about FileIOPermission class, but dont know how to implement it.

==> Detailed code.

Dim tempDir As New DirectoryInfo(path)
        Dim FileDetails(4) As String
        Dim iTem As ListViewItem
        If (tempDir.Attributes <> FileAttributes.System) Then
            Dim allFiles As FileInfo() = tempDir.GetFiles("*.pdf", SearchOption.AllDirectories)
            Dim oneFIle As FileInfo
            For Each oneFIle In allFiles
                FileDetails(0) = oneFIle.Name()
                FileDetails(1) = oneFIle.FullName()
                FileDetails(2) = oneFIle.Length() / (1024 * 1024)
                FileDetails(2) = FileDetails(2).Remove(5)
                iTem = New ListViewItem(FileDetails)
                ListView1.Items.Add(iTem)
            Next
        End If

Path is a string that contains the path required, in this case G:\

You won't find PDF files in this folder:

The System Volume Information folder is a hidden system folder that the System Restore tool uses to store its information and restore points. (MSDN)

So just ignore it.

Granted, GetFiles() does not allow you to ignore files/folders, so you'd have to PInvoke into FindFirstFile et al. to do searches effectively.
