一、dynamic

一、dynamic使用：

从一直使用动态类型写接口返回动态类型出现情况

1、返回接口每次不知道包含那些列（实体类解决）

2、操作的数据类型不可知（参与数值计算-实体类解决明确类型）

Dynamic 真不适合解决

        static void Main(string[] args)
        {
            string a = "{\"CaseId\":\"dae908a9-e28d-4e3e-be78-fa8c7ce1afaa\",\"DivisionId\":\"310112114\",\"Address\":\"\",\"UnitPrice\":\"0\",\"TotalPrice\":\"0\",\"QueryDate\":\"2019/7/9 8:59:39\",\"AvgUnitPrice\":\"0\",\"AvgPrice\":\"0\",\"MaxPrice\":\"0\",\"MinPrice\":\"0\",\"MangerPrice\":\"0\",\"Liveness\":\"1\",\"TotalCellNumber\":\"0\",\"QueryCount\":\"0\",\"ReturnCode\":\"-1\",\"Remark\":\"楼盘不可估\",\"EndDate\":\"2019/01/01 0:00:00\",\"ConstructionName\":\"\",\"ConstructionAlias\":\"\",\"BuildingName\":\"\",\"HouseName\":\"\",\"PropertyType\":\"\",\"QuotationCount\":\"0\"}";
            string b = "{\"CaseId\":\"b1a9f1ea-686c-4c95-9bc8-a23737ac715c\",\"DivisionId\":\"310109014\",\"Address\":\"虹口区临平北路60弄\",\"UnitPrice\":\"55676\",\"TotalPrice\":\"7259594\",\"QueryDate\":\"2019/7/9 10:37:52\",\"AvgUnitPrice\":\"55676\",\"AvgPrice\":\"55676\",\"MaxPrice\":\"62914\",\"MinPrice\":\"46891\",\"MangerPrice\":\"0.9\",\"Liveness\":\"3\",\"TotalCellNumber\":\"631\",\"QueryCount\":\"0\",\"ReturnCode\":\"1\",\"Remark\":\"估价成功\",\"EndDate\":\"1997/01/01 0:00:00\",\"ConstructionName\":\"临平北路60弄\",\"ConstructionAlias\":\"银欣花苑\",\"BuildingName\":\"\",\"HouseName\":\"\",\"PropertyType\":\"\",\"QuotationCount\":\"34\"}";
            dynamic aa = JsonConvert.DeserializeObject(a);
            dynamic bb = JsonConvert.DeserializeObject(b);
            var s = aa.GetType().Name;//JObject 
            //当值是'0' 输出  UnitPrice:'0' 与UnitPrice:0 区别   得出结果: 没有区别 输出都是{0}Value对象  判断0无区分  
            if (aa["UnitPrice"] != 0)
            {
                Console.Write("不等于0");///判断是否输出值
            }
            else
            {
                Console.Write("等于0");
            }
            if (bb["UnitPrice"] != 0)
            {
                Console.Write("不等于0");///判断是否输出值
            }
            else
            {
                Console.Write("等于0");
            }

        }

    }
