Json.net使用JsonProperty来获取inheritance的属性
您好我正在尝试使用Json.net反序列化此json代码。 它是关于特定电影的信息。 除了cast属性之外，一切都按预期工作。 在信用财产中inheritance的。 我为我的Movie类中的一个名为Actor的演员和一个这个actor类的列表做了一个类

public class Movie { [JsonProperty(PropertyName = "id")] public int ID { get; set; } [JsonProperty(PropertyName = "original_title")] public string Title { get; set; } [JsonProperty(PropertyName = "cast"] public List Lists { get; set; } }
Actor类：
public class Actor { #region Properties [JsonProperty(PropertyName = "id")] public int ActorId { get; set; } [JsonProperty(PropertyName = "name")] public string Name { get; set; } [JsonProperty(PropertyName = "character")] public string CharacterName { get; set; } [JsonProperty(PropertyName = "order")] public int Order { get; set; } [JsonProperty(PropertyName = "cast_id")] public int CastId { get; set; } [JsonProperty(PropertyName = "profile_path")] public string ProfilePath { get; set; } #endregion }
我想访问cast属性而不用一个名为credit的类来存储actor的列表。我想直接在Movie类中存储Actors列表。
反序列化的调用如下所示：
Movie test = JsonConvert.DeserializeObject(json);
我试图将Movie类上的JsonProperty编辑为例如cast.credits，但没有任何效果。
我看到了一个simelar问题的答案，但我不想手动这样做，我想自动。 Json获取底层数组而不检索其成员
提前致谢。
由于JSON中的强制转换属性不在顶级对象（电影）中，并且您不想引入中间Credits类，因此您需要使用自定义JsonConverter来弥补差距。 以下是转换器的外观：
public class MovieConverter : JsonConverter { public override bool CanConvert(Type objectType) { return (objectType == typeof(Movie)); } public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer) { JObject jo = JObject.Load(reader); Movie movie = jo.ToObject(); movie.Lists = jo.SelectToken("credits.cast").ToObject>(); return movie; } public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer) { throw new NotImplementedException(); } }
要使用转换器，只需将它的实例传递给JsonConvert.DeserializeObject()方法，如下所示：
Movie movie = JsonConvert.DeserializeObject(json, new MovieConverter());
这是一个演示：
class Program { static void Main(string[] args) { string json = @" { ""id"": 550, ""original_title"": ""Fight Club"", ""credits"": { ""cast"": [ { ""id"": 819, ""name"": ""Edward Norton"", ""character"": ""The Narrator"", ""order"": 0, ""cast_id"": 4, ""profile_path"": ""/eIkFHNlfretLS1spAcIoihKUS62.jpg"" }, { ""id"": 287, ""name"": ""Brad Pitt"", ""character"": ""Tyler Durden"", ""order"": 1, ""cast_id"": 5, ""profile_path"": ""/kc3M04QQAuZ9woUvH3Ju5T7ZqG5.jpg"" }, { ""id"": 1283, ""name"": ""Helena Bonham Carter"", ""character"": ""Marla Singer"", ""order"": 2, ""cast_id"": 6, ""profile_path"": ""/58oJPFG1wefMC0Vj7sFzHPrm67J.jpg"" }, { ""id"": 7470, ""name"": ""Meat Loaf"", ""character"": ""Robert 'Bob' Paulson"", ""order"": 3, ""cast_id"": 7, ""profile_path"": ""/pwNyXgegO1nlZ8uWT847JM8EjGj.jpg"" }, { ""id"": 7471, ""name"": ""Zach Grenier"", ""character"": ""Richard Chesler"", ""order"": 4, ""cast_id"": 8, ""profile_path"": ""/jghYiKdNkVehKpiVyE97AWrU9KQ.jpg"" } ] } }"; Movie movie = JsonConvert.DeserializeObject(json, new MovieConverter()); Console.WriteLine(movie.Title + " cast:"); foreach (Actor actor in movie.Lists) { string sep = new string('\t', actor.Name.Length > 14 ? 1 : 2); Console.WriteLine(actor.Name + sep + actor.CharacterName); } } }
输出：
Fight Club cast: Edward Norton The Narrator Brad Pitt Tyler Durden Helena Bonham Carter Marla Singer Meat Loaf Robert 'Bob' Paulson Zach Grenier Richard Chesler
我找到了一个可以忍受的解决方案。
var results = JsonConvert.DeserializeObject(json); Movie test = new Movie(); test.Lists = results.credits.cast.ToObject>();
