Retrieve volume name from networked mapped disk drive

I am using DriveInfo.GetDrivers() to take the names of the disk drives present on the machine and list them in a TreeView.

I made the code below that works, but it does not appear the names of network disks that my machine has access, only local disks.

foreach(DriveInfo drv in DriveInfo.GetDrives())
{
    TreeNode node = new TreeNode();
    node.ImageIndex = 0;
    node.SelectedImageIndex = 0;
    node.Text = drv.Name+drv.VolumeLabel; 
    node.Nodes.Add("");
    treeview.Nodes.Add(node);
    retorno = true;
}

When I concatenate with the drv.VolumeLabel that the networked disks stop appearing (concatenate to appear to the user the disk name for identification)

I'm thinking of a if to display them, however, the goal was to display the name of the disk in network, since much of the work will be on different networks.

Update:

I did a If to correctly display the disk name and display at least the letter of the DrIve network

if (drv.DriveType == DriveType.Network)
   node.Text = drv.Name;
else if (drv.DriveType == DriveType.Fixed)
   node.Text = drv.Name + drv.VolumeLabel;
else
   node.Text = drv.Name;

And is displayed like this:

The problem is that in this medium ai has pendrive connected, network HD and CD-Rom disk in the middle.
