Opendialog for showing Removable disks in c#
<p>I want to show a open dialog for the user, where the user can select only the files from the removable disks in the system. I am using the below code. But i need to get the Guid of removable disk to open the dialog.</p>

<p>Tell me how...</p>

<pre><code>System.Windows.Forms.OpenFileDialog dls = new System.Windows.Forms.OpenFileDialog();
dls.CustomPlaces.Clear();
foreach (DriveInfo Drive in ListDrives)
{
    if (Drive.DriveType == DriveType.Removable)
    {
        dls.CustomPlaces.Add(-----Guid of Drive------);
    }
    dls.ShowDialog();
}
</code></pre>
