如下是一个三层次的Json字符串的转换对象实例：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Arvato.CRM.DataTrans.ConsoleHost.Model
{
/// <summary>
/// Json接口
/// </summary>
public class MainJson<T>
{
/// <summary>
/// 1:成功 0：失败
/// </summary>
public int success { get; set; }
/// <summary>
/// 描述
/// </summary>
public string message { get; set; }
/// <summary>
/// 数据主体
/// </summary>
public body<T> body { get; set; }
}
/// <summary>
/// 数据主体
/// </summary>
/// <typeparam name="T"></typeparam>
public class body<T>
{
/// <summary>
/// 实体
/// </summary>
public List<T> item { get; set; }
/// <summary>
/// 表示总记录数
/// </summary>
public int total { get; set; }
}
/// <summary>
/// 城市列表
/// </summary>
public class CITY
{
/// <summary>
/// 城市编码
/// </summary>
public int? cityid { get; set; }
/// <summary>
/// 城市名称
/// </summary>
public object name { get; set; }
/// <summary>
/// 最后更新时间戳
/// </summary>
public DateTime? utime { get; set; }
}
}
调用时：
MainJson<CITY> city_List = JsonHelper.JSONToList<CITY>(JsonStr);
再如2个层次的Json字符串转换对象时：
namespace CrazyAuchan.Common
{
public class MainJson<T>
{
public int total { get; set; }
public string message { get; set; }
public int pageNo { get; set; }
public int pageSize { get; set; }
public int status { get; set; }
////0:新注册获得 1:消费获得 2:分享成功获得
public int source { get; set; }
public List<T> data { get; set; }
}
public class CouponInfo
{
public string activityNo { get; set; }
public string couponNo { get; set; }
//Failure(0L, "已失效"), NoFailure(1L, "未失效")
//0:已失效 1：未失效
public int overdueStatus { get; set; }
//HasShare(0L, "已分享"), DoesNotShare(1L, "未分享");
//0:已分享 1：未分享
public int shareStatus { get; set; }
////ANewRegistrationToObtain(0L, "新注册获得"), ConsumerToObtain(1L, "消费获得"), ShareSuccess(2L, "分享成功获得");
////0:新注册获得 1:消费获得 2:分享成功获得
public int source { get; set; }
//couponNo的HTML二维码
public string couponCode { get; set; }
//总条数
public int itemCount { get; set; }
}
}
调用时的代码：
var CouponList1 = new List<CouponInfo>();
var
CouponJson = "{"data":
[
{"activityNo":"1111","couponNo":"7200002000095","overdueStatus":1,"shareStatus":0},{"activityNo":"1111","couponNo":"7200000200094","overdueStatus":1,"shareStatus":1},
{"activityNo":"1111","couponNo":"7200002000093","overdueStatus":0,"shareStatus":0},{"activityNo":"1111","couponNo":"7200000200092","overdueStatus":1,"shareStatus":0},
{"activityNo":"1111","couponNo":"7200000200091","overdueStatus":1,"shareStatus":0},{"activityNo":"1111","couponNo":"7200000200090","overdueStatus":1,"shareStatus":1}
],
"total":16,
"message":"符合申领资格!",
"pageNo":1,
"pageSize":6,
"status":1,
"source":1
}";
if (!string.IsNullOrEmpty(CouponJson))
{
MainJson<CouponInfo> MainCouponInfo = JsonHelper.JSONToList<CouponInfo>(CouponJson);
if (MainCouponInfo.status == 1)
{
itemCount = MainCouponInfo.total;
CouponList1 = MainCouponInfo.data.Where(p => !string.IsNullOrEmpty(p.couponNo) && p.couponNo.Length == 13).ToList();
}
}
foreach (var coupon in CouponList1)
{
if (coupon != null && !string.IsNullOrEmpty(coupon.couponNo))
{
coupon.itemCount = itemCount;
coupon.couponCode = BarCodeHelper.getBarCode13(coupon.couponNo, 2, 40);//"7200000000090"
}
}
var json = JsonHelper.JsonSerialize(CouponList1);
