json 属性作为 c# model class 中的数字？

Question

我如何构建 Model class 来反序列化 json 像这样：-

{"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？

Answer 1

如果您在 model 上将data项实现为Dictionary ，则这些数字将是此Dictionary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; }
}

Answer 2

您可以将这些数字视为字典的键。 所以可以像这样转换它们：

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;}
}

（测试看这个 dotnetfiddle 例子）

显然只有在没有数字出现两次或更多的情况下才有可能。
