对结果集进行分页显示

步骤：

1 有一个方法调用处。

2 处理的Request实例中page属性是指当前页，pageSize属性石指一页显示多少条。

3 编写递归方法

3 计算当page * pageSize 是否小于Request的总数量OrderTotal。

if (recursive && page * pageSize < response.OrderSearch.OrderTotal)

代码实例：

        #region 订单列表示例
        /// <summary>
        /// 获取订单列表
        /// </summary>
        /// <param name="startDate">开始时间</param>
        /// <param name="endDate">结束的时间</param>
        /// <param name="orderState">订单状态</param>
        /// <returns>京东平台线上商品列表结果集</returns>
        public List<OrderInfo> GetOrderList(DateTime startDate, DateTime endDate, string orderState)
        {
            Int32 totalCount;
            string newApiOrderStates = "WAIT_SELLER_STOCK_OUT,WAIT_SELLER_DELIVERY,TRADE_CANCELED,WAIT_BUYER_PAY,FINISHED_L";
            if (newApiOrderStates.IndexOf(orderState, StringComparison.InvariantCultureIgnoreCase) >= 0)
            {
                return GetOrderList(startDate, endDate, orderState, 1, 100, out totalCount, true);
            }
            else
            {
                totalCount = 0;
                return new List<OrderInfo>();
            }
        }
        #endregion
