Tuple的使用：

                case 4:
                    return new Tuple<string, string>("上午", $"{this.SendTime:yyyy-MM-dd} 09:00-12:00");
                case 8:
                    return new Tuple<string, string>("下午", $"{this.SendTime:yyyy-MM-dd} 12:00-18:00");

            }

        }
//DliveryWays = t.DevileryPeriod().Item1,

    }

    static void AnyElementNumber()
