        LoginService service = new LoginService（）;
        public int getLoginUserLid（string user string password）
        {
            return service.getLoginUserLid（user password）;
        }

        public int getRoleid（int LoginUserId）
        {
            return service.getRoleid（LoginUserId）;
        }

        public List getRolePowerList（int RoleId）
        {
            return service.getRolePowerList（RoleId）;
