Json反射成对象（随笔日记）

 {

orderId:1,

uid:2,

yohoCoinCost:10,

farePrice:15,

couponCostId:1,

proList:[

{

productId:102000,

productSizeId:1,

productNum:3

}],

promoList:[

{

promotionId:63,

promoType:2,

promo_ProList:[

{

productId:102001,

productSizeId:3,

productNum:3

}]

}]

}

 

以上是json格式，然后创建与json元素名称对应的实体

[Serializable] public class PromoOrder : ICloneable { /// <summary> /// 订单ID /// </summary> public int OrderId { get; set; } /// <summary> /// 用户ID /// </summary> public int Uid { get; set; } /// <summary> /// 用户使用的YOHO币数量 /// </summary> public double YohoCoinCost { get; set; } /// <summary> /// 用户使用的优惠券编码 /// </summary> public int CouponCostId { get; set; } /// <summary> /// 订单运费 /// </summary> public double FarePrice { get; set; } /// <summary> /// 订单商品列表 /// </summary> public List<PromoProduct> ProList { get; set; } /// <summary> /// 订单促销信息列表 /// </summary> public List<Promotion> PromoList { get; set; } #region ICloneable 成员 /// <summary> /// 复制一份数据 /// </summary> /// <returns></returns> public object Clone() { return new PromoOrder() { CouponCostId = this.CouponCostId, FarePrice = this.FarePrice, OrderId = this.OrderId, ProList = (List<PromoProduct>)ListClone.Clone<PromoProduct>(this.ProList), PromoList = (List<Promotion>)ListClone.Clone<Promotion>(this.PromoList), Uid = this.Uid, YohoCoinCost = this.YohoCoinCost }; } #endregion }

然后下载插件Newtonsoft.Json.Net20.dll并引用

具体创建代码是：

string jsonStr = context.Request.Params["promocode"].ToString().Trim();//此为获取的json字符串 JObject obj = JObject.Parse(jsonStr); JsonSerializer serializer = new JsonSerializer(); order = (PromoOrder)serializer.Deserialize(new JTokenReader(obj), typeof(PromoOrder));//创建实例
