把多个menu绑定到treeview

private void  GetMenuCount(System.Web.UI.Control parentCountol)//找到memu的个数

                }
               
                GetMenuCount(c);
            }
        }
       
    }

    private void BindTreeView(MenuItemCollection menuItemCollection,TreeNodeCollection treeNodeCollection)//把menu绑定到treeview上
    {
        foreach (MenuItem menuItem in menuItemCollection)
        {
            TreeNode treeNode = new TreeNode();
            treeNode.Text = menuItem.Text;
