将包含多个对象的 json 对象反序列化为列表

Question

我正在尝试使用英雄联盟 api 从 [1]http://ddragon.leagueoflegends.com/cdn/6.24.1/data/en_GB/champion.json[1]:http://ddragon.leagueoflegends.com/cdn/6.24.1/data/en_GB/champion.json获取冠军列表

这会像

一样返回 json

我应该能够像这样反序列化：

 class ChampionService : BaseService
{
    public List<Champion> GetChampions()
    {
        HttpWebRequest req = CreateRequest(ApiUrl);
        HttpWebResponse res = (HttpWebResponse)req.GetResponse();
        string json;

        using (StreamReader reader = new StreamReader(res.GetResponseStream()))
        {
            json = reader.ReadToEnd();
            return JsonConvert.DeserializeObject<List<Champion>>(json);
        }
    }
}

如果数据是一个数组，我的 Champion 类：

public class Champion
{
    [JsonProperty("name")]
    public string Name { get; set; }
    [JsonProperty("key")]
    public int Key { get; set; }
    [JsonProperty("tags")]
    public List<string> tags { get; set; }
}

但是，由于 api 返回包含更多对象的数据对象，因此不能将其视为数组，因此这不起作用。有什么好方法可以让这个工作吗？

您可以通过一个作为冠军字典占位符的类来对 JSON 进行不同的建模：

class ApiResult
{
    [JsonProperty("data")]
    public Dictionary<string, Champion> Champions { get; set; }
}

然后反序列化，你会这样做：

var result = JsonConvert.DeserializeObject<ApiResult>(json);

您可以稍后使用 Champions 字典中的 ToList() 方法检索冠军列表。
