【问题描述】：
我一直在尝试反序列化嵌套的 json。我从world bank api 获取 JSON。我想从 JSON 中获取 country id 并将值绑定到下拉列表中。
我不确定，怎么了？
其他信息 反序列化代码
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); }
这是下面给出的 Json。

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; }
}
}

您遇到错误了吗？

@MarkC。我在线收到错误：Info = JsonConvert.DeserializeObject
- >(json);无法将当前 JSON 数组（例如 [1,2,3]）反序列化为类型 'ejemlo.Models.Paginacion'，因为该类型需要 JSON 对象（例如 {"name":"value"}）才能正确反序列化。跨度>
