如何反序列化 JSON？

Question

我之前没有对 JSON 做过任何事情......所以我可能只是错过了一步。

这是我要反序列化的 JSON 示例：

{"item":{"icon":"http://services.runescape.com/m=itemdb_rs/4765_obj_sprite.gif?id=4798","icon_large":"http://services.runescape.com/m=itemdb_rs/4765_obj_big.gif?id=4798","id":4798,"type":"Ammo","typeIcon":"http://www.runescape.com/img/categories/Ammo","name":"Adamant brutal","description":"Blunt adamantite arrow...ouch","current":{"trend":"neutral","price":237},"today":{"trend":"neutral","price":0},"members":"true","day30":{"trend":"positive","change":"+1.0%"},"day90":{"trend":"negative","change":"-0.0%"},"day180":{"trend":"positive","change":"+0.0%"}}}

我将它放入“Json 2 C#”并最终创建了这个新的 .cs 文件：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace RSTool.Models
{

    public class Current
    {
        public string trend { get; set; }
        public int price { get; set; }
    }

    public class Today
    {
        public string trend { get; set; }
        public int price { get; set; }
    }

    public class Day30
    {
        public string trend { get; set; }
        public string change { get; set; }
    }

    public class Day90
    {
        public string trend { get; set; }
        public string change { get; set; }
    }

    public class Day180
    {
        public string trend { get; set; }
        public string change { get; set; }
    }

    public class Item
    {
        public string icon { get; set; }
        public string icon_large { get; set; }
        public int id { get; set; }
        public string type { get; set; }
        public string typeIcon { get; set; }
        public string name { get; set; }
        public string description { get; set; }
        public Current current { get; set; }
        public Today today { get; set; }
        public string members { get; set; }
        public Day30 day30 { get; set; }
        public Day90 day90 { get; set; }
        public Day180 day180 { get; set; }
    }

    public class RootObject
    {
        public Item item { get; set; }
    }
}

所以，我有课。我可以从它的位置检索 JSON 作为字符串，但我真的不知道如何反序列化它......我已经安装了 Newtonsoft.Json 并尝试使用 PopulateObject 和 Deserializer 但没有任何运气......

假设我的 JSON 存储为名为“json”的字符串，例如，我将如何存储该查询然后检索项目名称？

Answer 1

用途：

var deserialized = JsonConvert.DeserializeObject<RootObject>(json);

根据您提供的代码，我刚刚测试成功。

然后您可以正常访问对象的属性：

MessageBox.Show(deserialized.item.name);
