我正在尝试反序列化我从这里得到的一些 json https://www.reddit.com/r/tf2/hot/.json?limit=10&rawjson=1，但所有带有 newtonsoft json.net 的示例都显示为简单的 json 对象。
如何将其反序列化为一个不错的对象？
【问题讨论】：
您必须创建自己的对象并在反序列化中指定对象。
YourNewRootClass result =
JsonSerializer.Deserialize<YourNewRootClass>(jsonString);
您可以使用此站点创建一个您需要的 json 格式的虚拟对象：https://json2csharp.com/
更新
用你的例子：
Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);
然后：
// Root myDeserializedClass = JsonConvert.DeserializeObject<Root>(myJsonResponse);

【讨论】：
在快速浏览在线可用信息后。哎呀，这种格式很烦人。
我建议您首先定义一个基本类型、每个“种类”的子类和一个 custom converter 来反序列化它们。可能看起来像这样；
public abstract class RedditBase {
}
public class RedditListing : RedditBase {
public string Before { get; set; }
public string After { get; set; }
public List<RedditBase> Children { get; set; }
}
public class RedditConverter : JsonConverter<RedditBase>
{
public override void WriteJson(JsonWriter writer, RedditBase value, JsonSerializer serializer)
=> throw new NotImplementedException();
public override RedditBase ReadJson(JsonReader reader, Type objectType, RedditBase existingValue, bool hasExistingValue, JsonSerializer serializer)
{
var obj = JObject.Load(reader);
var data = (JObject)obj["data"];
switch ((string)obj["kind"])
{
case "Listing":
{
var list = new RedditListing();
serializer.Populate(data.CreateReader(), list);
return list;
}
default:
throw new NotImplementedException();
}
}
}
