you should use the
category_tree.GetCheckedNodes() method in order to get the collection of checked nodes in treeview.

As you can see the method GetCheckedNodes returns an array of TreeNode object.
So you may simply loop through the collection (using foreach statement or etc) to write its value.
Or use category_tree.GetCheckedNodes()[0] to get the first node of this collection and so on.

But do you mean selected node or checked nodes?
Definitelly you cannot loop through ftv.SelectedNode because it is not a collection. You should loop through the result of ftv.GetCheckedNodes()
