            if (Session["power"] == null)
            {
                Response.Redirect("Login.aspx");
            }
            Type type = this.GetType();
            string p = "getJson";//前台传来的方法名
            type.InvokeMember(p, System.Reflection.BindingFlags.NonPublic, null, null, null);
        }

        private string getJson(string p)

            p += p;
            return p;
        }
