【中文标题】使用数组中的数组对 JSON 进行反序列化【英文标题】：Desearalising JSON with arrays in arrays 【发布时间】：2021-02-17 15:33:23 【问题描述】：我花了一段时间试图弄清楚如何对这个 JSON 文件进行消毒并获取每个产品
ID、姓名、收集费用和天气情况
我目前正在 C# 类中使用 Newtonsoft.Json 尝试此操作。
有人能指出我正确的方向吗？ 非常感谢

【问题讨论】：
@JaromandaX 抱歉，我忘了提到我在课堂上收到了相同的数据，但 JSON 数据。堆栈溢出不允许我显示整个 JSON 文本，谢谢:) @JaromandaX 生病添加一些 json @JaromandaX 谢谢你，我没有意识到你可以做到这一点，我是 JSON 新手，对网络抓取还很陌生 你的问题不是数组中的数组...问题是 JSON 中的 JSON ...问题是categoryList 只是一个字符串（作为 JSON 格式）所以你必须解析它解析整个 JSON 后的值
@dbc 谢谢，因为我只需要 6 个值，所以我决定将对象转换为动态数据类型，因此我不必考虑所有字段
【参考方案1】：
public static List<JJs.ITEMS> JJSGetProductHTML(String Term)
string url = "https://www.website.com/api/product-search-agg/api/v1/product/websearch?b=DG-MW&page=0&q=" + Term+ "&size=12&sortType=search&format=json";
WebClient WC = new WebClient();
string JSON = WC.DownloadString(url);
var onject,= JsonConvert.DeserializeObject<dynamic>(JSON);
string s = onject._embedded.products[0].ToString();
List<JJs.ITEMS> products = new List<JJs.ITEMS>();
foreach (var m in onject._embedded.products)
JJs.ITEMS newitem = new JJs.ITEMS();
newitem.Name = m.jsonFriendlyItemName.ToString();
newitem.itemId = m.itemId.ToString();
newitem.price = m.collection.price.ToString();
try
m.offer.ToString(); newitem.Promoend = m.offer.promoEnd.ToString(); newitem.Promo = true;
catch
newitem.Promo = false; ;
products.Add(newitem);
return products;
因为我不想要所有字段，所以我对其进行了序列化，然后使用“.jsonFriendlyItemName”、“.itemId”.. 仅获取我正在寻找的值
感谢@JaromandaX、@Peter B 和 @dbc 的帮助
