我如何构建一个模型类来反序列化一个json，如下所示:-
{"query":{"apikey":"65320-2d8b-11eb-864","continent":"Africa"},"data":{"0":{"country_id":1,"name":"Africa","country_code":null,"continent":"Africa"},"9":{"country_id":10,"name":"Algeria","country_code":"dz","continent":"Africa"},"11":{"country_id":12,"name":"Angola","country_code":"ao","continent":"Africa"},"23":{"country_id":24,"name":"Botswana","country_code":"bw","continent":"Africa"},"27":{"country_id":28,"name":"Cameroon","country_code":"cm","continent":"Africa"},"32":{"country_id":33,"name":"Congo","country_code":"cg","continent":"Africa"},"39":{"country_id":40,"name":"Egypt","country_code":"eg","continent":"Africa"},"48":{"country_id":49,"name":"Ghana","country_code":"gh","continent":"Africa"},"62":{"country_id":63,"name":"Ivory Coast","country_code":"ci","continent":"Africa"},"67":{"country_id":68,"name":"Kenya","country_code":"ke","continent":"Africa"},"80":{"country_id":81,"name":"Morocco","country_code":"ma","continent":"Africa"},"85":{"country_id":86,"name":"Nigeria","country_code":"ng","continent":"Africa"},"102":{"country_id":103,"name":"Rwanda","country_code":"rw","continent":"Africa"},"106":{"country_id":107,"name":"Senegal","country_code":"sn","continent":"Africa"},"111":{"country_id":112,"name":"South Africa","country_code":"za","continent":"Africa"},"115":{"country_id":116,"name":"Tanzania","country_code":"tz","continent":"Africa"},"118":{"country_id":119,"name":"Tunisia","country_code":"tn","continent":"Africa"},"120":{"country_id":121,"name":"Uganda","country_code":"ug","continent":"Africa"},"129":{"country_id":130,"name":"Zambia","country_code":"zm","continent":"Africa"},"130":{"country_id":131,"name":"Zimbabwe","country_code":"zw","continent":"Africa"}}}
问题出在“0”，“9”，“11”等数字上！如何将这些数字转换为model类中的一个属性？
如果将data项实现为模型上的字典，则这些数字将是此字典的键。
public class Model
{
[JsonProperty("query")]
public Query query {get; set; }
[JsonProperty("data")]
public Dictionary<string, Country> Data { get; set; }
}
public class Country
{
[JsonProperty("country_id")]
public int Id { get; set; }
[JsonProperty("name")]
public string Name { get; set; }
[JsonProperty("country_code")]
public string Code { get; set; }
[JsonProperty("continent")]
public string Continent { get; set; }
}
public class Query
{
[JsonProperty("apikey")]
public string ApiKey { get; set; }
[JsonProperty("continent")]
public string Continent { get; set; }
}
您可以将这些数字视为字典的关键字。所以可以这样转换它们:
using System;
using System.Collections.Generic;
using Newtonsoft.Json;
public class Program
{
public static void Main()
{
var testJson = "{\"data\":{\"11\": \"test11\"}}";
var deserialized = (TestClass) JsonConvert.DeserializeObject(testJson, typeof(TestClass));
Console.WriteLine(deserialized.Data[11]);
}
}
public class TestClass
{
public Dictionary<int, string> Data {get;set;}
}
（要进行测试，请参阅此dotnetfiddle示例）
显然只有在没有数字出现两次或更多的情况下才有可能。
