我就废话不多说啦，大家还是直接看代码吧~
[

上面为要解析的JSON数据
var json = "[{\"orderNo\": \"3213123123123\",\"time\": \"2016-09-09 12:23:33\",\"orderStatus\":\"1\", \"freeShipping\": true, \"fullCut\": 20,\"originalCost\": 340, \"actualPayment\": 320,\"goods\": [";
json += " {\"UserId\": \"5\",\"GoodsId\": \"8\", \"Total\": 40, \"Number\": 2, \"Price\": \"20.00\", \"shopname\": \"两颗牙\", \"manmoney\": \"200\", \"jianmoney\": \"0\",\"jianyoufei\": \"10\"},";
json += " {\"UserId\": \"5\",\"GoodsId\": \"7\", \"Total\": 60, \"Number\": 1, \"Price\": \"60.00\",\"shopname\": \"两颗牙\", \"manmoney\": \"200\", \"jianmoney\": \"0\",\"jianyoufei\": \"10\"},";
json += " ]} ]";
OrderDetails[] datas = JsonConvert.DeserializeObject(json);
List insert = new List();
foreach (OrderDetails data in datas)
{
var shopname = string.Empty;//判断是否同一个商家
foreach (var item in data.goods)
{
OrderDetailsInsert getinfo = new OrderDetailsInsert();
getinfo.orderno = data.orderno;
getinfo.time = data.time;
getinfo.orderStatus = data.orderStatus;
getinfo.actualPayment = data.actualPayment;
getinfo.orderno = data.orderno;
if (data.freeShipping == true)
{
getinfo.Remark = "此商品符合包邮条件及满" + item.manmoney + "减" + data.fullCut + "条件：订单总金额:" + data.originalCost + "符合满减条件减去：" + data.fullCut + "实际付款金额:" + data.actualPayment;
}
else if (!string.IsNullOrEmpty(data.fullCut.ToString()) && data.fullCut != 0)
{
getinfo.Remark = "此商品符合满" + item.manmoney + "减" + data.fullCut + "条件：订单总金额:" + data.originalCost + "符合满减条件减去：" + data.fullCut + "实际付款金额:" + data.actualPayment;
}
else
{
getinfo.Remark = "订单实际付款金额:" + data.actualPayment;
}
getinfo.GoodsId = item.GoodsId;
getinfo.Total = item.Total;
getinfo.Number = item.Number;
getinfo.Price = item.Price;
insert.Add(getinfo);
}
}
要用的对象类
public class OrderDetailsInsert
{
public string orderno { get; set; }
public DateTime time { get; set; }
public char orderStatus { get; set; }
public Decimal actualPayment { get; set; }
public int GoodsId { get; set; }
public string Total { get; set; }
public int Number { get; set; }
public string Price { get; set; }
public string Remark { get; set; }
}
public class OrderDetails
{
public string orderno { get; set; }
public DateTime time { get; set; }
public char orderStatus { get; set; }
public bool freeShipping { get; set; }
public Decimal fullCut { get; set; }
public Decimal originalCost { get; set; }
public Decimal actualPayment { get; set; }
public GoodsInfoList[] goods { get; set; }
}
public class GoodsInfoList
{
public int UserId { get; set; }
public int GoodsId { get; set; }
public string Total { get; set; }
public int Number { get; set; }
public string Price { get; set; }
public string shopname { get; set; }
public string manmoney { get; set; }
}
效果图：
补充：c#使用 Newtonsoft.Json 实现多态序列化
有时候会碰到以下情况
1.定义了一个类型为A的字段，但在实例化时使用的是它的派生类B。
2.定义了一个存储基类型A的集合，但实际上里面包含了各种各样的派生类。
上述两种情况在序列化的时候没有问题，但在反序列化的时候程序并不能将其转化为成派生类。
Newtonsoft.Json提供了一个JsonConverter特性，我们可以自定义某个数据的json读写方式以达成多态序列化的目的。
源码链接
1.自定义转化类
using System;
using System.Collections.Generic;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
using UnityEngine;
namespace XFramework.JsonConvter
{
///
/// 用于多态列表的转化
///
/// : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return true;
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
var jObject = JObject.Load(reader);
List values = new List();
foreach (var item in jObject.Properties())
{
Type type = Type.GetType(item.Name);
var value = item.Value.ToObject(type);
values.Add((T)value);
}
return values;
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
var values = (List)value;
JObject jObject = new JObject();
foreach (var item in values)
{
jObject.Add(item.GetType().FullName, JToken.FromObject(item));
}
var p = jObject.Properties();
foreach (var item in p)
{
Debug.Log(item.Name);
}
serializer.Serialize(writer, jObject);
}
}
///
/// 用于多态序列化
///
public class PolyConverter : JsonConverter
{
public override bool CanConvert(Type objectType)
{
return true;
}
public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
{
var jObject = JObject.Load(reader);
foreach (var item in jObject.Properties())
{
Type type = Type.GetType(item.Name);
var value = item.Value.ToObject(type);
return value;
}
return null;
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
JObject jObject = new JObject();
jObject.Add(value.GetType().FullName, JToken.FromObject(value));
serializer.Serialize(writer, jObject);
}
}
}
2.使用方式
DataBase是自己定义的一个数据基类,按照以下写法，再利用Newtonsoft 的API 序列化和反序列化TestData就可以成功实现多态读写了。
using XFramework.JsonConvter;
using Newtonsoft.Json;
public class TestData
{
// 对应第一种情况
[JsonConverter(typeof(PolyConverter))]
public DataBase datas;
// 对应第二种情况
[JsonConverter(typeof(PolyListConverter))]
public List powerList;
}
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。如有错误或未考虑完全的地方，望不吝赐教。
