[英]How to convert JSON output to c# objects and store them into an array
我正在尝试将JSON输出反序列化为.net对象,但将输出获取为null。
我已编写此代码来获取JSON数据并反序列化。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Net;
using System.IO;
using Newtonsoft.Json;
namespace ConsoleApp1
{
public enum httpverb
{
GET,
POST,
PUT,
DELETE
}
public class Item
{
public string item_id { get; set; }
public string name { get; set; }
public string item_name { get; set; }
public string hsn_or_sac { get; set; }
public string sku { get; set; }
public string image_name { get; set; }
public string status { get; set; }
public string source { get; set; }
public string description { get; set; }
public string cf_category { get; set; }
public string cf_maximum_retail_price_mrp { get; set; }
public DateTime created_time { get; set; }
public DateTime last_modified_time { get; set; }
public bool track_serial_number { get; set; }
}
class APIs
{
xxxxxcode goes here to fetch JSON from API and store into variable strResponseValue
string Jsoncontent = strResponseValue; //Jsoncontent holds json data
Item books = JsonConvert.DeserializeObject<Item>(Jsoncontent);
//how to access each object.
}
}
这是必须反序列化的JSON输出。

提供的JSON的输出必须反序列化为C#对象并存储到数组中。
您需要提供一个RootObject类,该类具有Code,Message和Items的属性。
然后,您反序列化到根对象,并访问items数组。
您必须在代码中添加此根类:
public class Root
{
public string code { get; set; }
public string message { get; set; }
public Item[] items { get; set; }
}
然后在现有的Item类中添加或删除所需的属性。 例如,在输入JSON中,有比类更多的属性,如果需要更多属性,只需在Item类中添加它们即可。 我使用了您提供的课程。
然后您执行以下操作:
var inputObj = JsonConvert.DeserializeObject<Root>(json);
您需要以下NuGet软件包:Newtonsoft.Json
上面代码中的json是包含您提供的整个JSON的字符串变量。 请注意,在您提供的json中,末尾缺少“}”。
inputObj是Root类类型的对象,并且包含所有项目的数组。 例如inputObj.items
如果您需要更多帮助,请在下面评论。
干杯
您的模型将像这样尝试
public class ItemTaxPreference
{
public string tax_specification { get; set; }
public int tax_type { get; set; }

它没有进行反序列化,因为您没有正确添加根级对象。
我为您的JSON响应建模,并制作了POCO以适当的pascal大小写公共属性对其进行建模,如下所示:
