如何在 mvc C# 中使用 newtonsoft 反序列化嵌套的 json 字符串

Question

我一直在尝试反序列化嵌套的 json。我正在从世界银行 api获取 JSON 。我想country id从 JSON 和值中获取绑定到下拉列表中的值。

我不确定，怎么了？

反序列化的附加信息代码

JObject googleSearch = JObject.Parse(googleSearchText);

// get JSON result objects into a list IList<JToken> results =

googleSearch["responseData"]["results"].Children().ToList();

// serialize JSON results into .NET objects IList<SearchResult>

searchResults = new List<SearchResult>(); foreach (JToken result in results) {

// JToken.ToObject is a helper method that uses JsonSerializer internally

SearchResult searchResult = result.ToObject<SearchResult>();

searchResults.Add(searchResult); }

鉴于下面的代码。这是我的模型：

Using Newtonsoft.Json;

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

    namespace ejemplo.Models

   {

    public class Paginacion

    {

        public Paginacion()

        {

            this.List = new List<Data>();

        }

        [JsonProperty("page")]

        public int Page { get; set; }

        [JsonProperty("pages")]

        public int Pages { get; set; }

        [JsonProperty("per_page")]

        public string PerPage { get; set; }

        [JsonProperty("total")]

        public int Total { get; set; }

        public List<Data> List { get; set; }

    }

    public class Country

    {

        [JsonProperty("id")]

        public string Id { get; set; }

        [JsonProperty("value")]

        public string Value { get; set; }

    }

    public class Indicator

    {

        [JsonProperty("id")]

        public string Id { get; set; }

        [JsonProperty("value")]

        public string Value { get; set; }

    }

public class Data

{

    public Data()

    {

        this.Indicator = new Indicator();

        this.Country = new Country();

    }

    [JsonProperty("indicator")]

    public Indicator Indicator { get; set; }

    [JsonProperty("country")]

    public Country Country { get; set; }

    [JsonProperty("date")]

    public string Date { get; set; }

    [JsonProperty("value")]

    public string Value { get; set; }

    [JsonProperty("decimal")]

    public string Decimal { get; set; }

   }

}

Answer 1

你的 json 是一个数组所以你需要使用 JArroy.Parse 而不是 JObject.Parse代替JObject googleSearch = JObject.Parse(googleSearchText);为了JArray googleSearch = JArray.Parse(googleSearchText);然后您可以导航 de JArray 以查找您的值。// get JSON result objects into a list IList<JToken> results =var results = googleSearch.Last.ToList();// serialize JSON results into .NET objects IList<SearchResult>List<Country> countyList = new List<Country>();foreach (JToken result in results){&nbsp; &nbsp; // JToken.ToObject is a helper method that uses JsonSerializer internally&nbsp; &nbsp; var country = new Country { Id = result["id"].ToString(), Value = result["name"].ToString() };&nbsp; &nbsp; countyList.Add(country);}

Answer 2

虽然它是有效的 json，但序列化器需要一个根对象，因此如果您可以将 json 输出修改为根对象，您就可以正确地序列化它：[&nbsp;&nbsp;&nbsp; &nbsp; {&nbsp; &nbsp; &nbsp; &nbsp;"page": {&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "page":1,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "pages":31,&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "per_page":"10",&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "total":304&nbsp; &nbsp; &nbsp; &nbsp;},&nbsp; &nbsp; &nbsp; &nbsp;"data": [&nbsp;&nbsp;&nbsp;
