        MsgBox(TreeView1.SelectedNode.Parent.Index & "" & TreeView1.SelectedNode.NextNode.Index & "" & TreeView1.SelectedNode.NextNode.Index)

    End Sub

but not Get Drive Node and can not get the node if there are more Subfolder...

Why are you looking at the NextNode instead of the SelectedNode?

How about:

VB.NET

Private Sub Button10_Click(sender As Object, e As EventArgs) Handles Button10.Click
    Dim path As New Stack(Of Integer)
    Dim node As TreeNode = TreeView1.SelectedNode
    While node IsNot Nothing
        path.Push(node.Index)
        node = node.Parent
    End While
    
    Dim nodePath As String = String.Join(",", path)
    MsgBox(nodePath)
End Sub
