首先:我是使用 JSON 的新手,我使用此处的答案使用 Json.Net 将来自 Pokemon API 的数据反序列化为 C# 类(Pokemon 类)。我使用http://json2csharp.com来帮助我定义我的类,它看起来像这样:
public class Pokemon
{
public Pokemon(string json)
{
JsonConvert.PopulateObject(json, this, PokeApi.JsonSerializerSettings);
}
[JsonProperty("name")]
public string Name { get; set; }
[JsonProperty("evolutions")]
public Evolutions evolutions { get; set; }
[JsonProperty("national_id")]
public int national_id { get; set; }
}
具有许多其他属性,例如 resource_uri、攻击统计等。
正如上述链接上提供的答案所说,我像这样使用 JsonConvert.DeserializeObject(json) :
public Pokemon GetPokemon(int nationalId)
{
using (WebClient client = new WebClient())
{
var json = client.DownloadString("http://pokeapi.co/api/v1/pokemon/" + nationalId + "/");
var output = JsonConvert.DeserializeObject<Pokemon>(json);
return output;
}
}
但是,我不断收到一个异常,上面写着“无法将当前的 JSON 数组(例如 [1,2,3])反序列化为 'Evolutions' 类型,因为该类型需要 JSON 对象......”
我发现很多其他问题都在问同样的问题,但我对最重要的答案感到困惑——有时答案是使用 JsonProperty,有时是使用 JsonConverter,但没有真正解释所有这些意味着什么。我需要两者吗?
