节点反向追加得到根

   INode currentNode = this.keybutton.keyEntry;
            TreeNode rootTreeNode = null;
            while (currentNode != null)

                LogUtil.writeLog("获取当前:" + currentNode.getNodeLabel());
                if (rootTreeNode != null)

                    LogUtil.writeLog("操作节点:" + temp.Name);
                    rootTreeNode = new TreeNode(currentNode.getNodeLabel(), new TreeNode[] { temp });
                    LogUtil.writeLog("操作节点:" + temp.Name + "追加" + currentNode.getNodeLabel());
