Movie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<Actor> Lists { get; set; }
}
的
演员类：
The Actor class:
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
}
我要访问的投物业的没有制作一类叫做如。学分演员名单存放在我直接想在电影类演员的商店名单
I want to access the cast property without making a class called e.g. credits to store the list of actors in. I want directly to store list of Actors in the Movie class.
该呼吁反序列化看起来是这样的：
The call for deserialize looks like this:
Movie test = JsonConvert.DeserializeObject<Movie>(json);
我试图编辑JsonProperty在电影类如 cast.credits 但没有任何工程。
我看到一个答案，一个simelar问题，但我并不想这样做，我手动自动希望它。 的Json GET而不检索其成员底层数组
I saw an answer to a simelar question but i do not want to do this manually i want it automatically. Json get underlying array without retrieving its member
先谢谢了。
推荐答案
由于投中的JSON属性不是顶层对象（电影）里面，你不希望引入一个中间积分类，那么你会需要使用自定义的 JsonConverter 来弥补缺口。这里是转换器可能看起来是这样的：
Since the cast property in the JSON is not inside the top-level object (the movie), and you do not want to introduce an intermediate Credits class, then you'll need to use a custom JsonConverter to bridge the gap. Here is what the converter might look like:
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>();
movie.Lists = jo.SelectToken("credits.cast").ToObject<List<Actor>>();
return movie;
}
public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
{
throw new NotImplementedException();
}
}
要使用转换器，只是通过它的一个实例像这样的 JsonConvert.DeserializeObject（）方法：
To use the converter, just pass an instance of it to the JsonConvert.DeserializeObject() method like this:
Movie movie = JsonConvert.DeserializeObject<Movie>(json, new MovieConverter());
下面是一个演示：
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""
},
{

""character"": ""Robert 'Bob' Paulson"",
""order"": 3,
""cast_id"": 7,

},
{
""id"": 7471,
""name"": ""Zach Grenier"",
""character"": ""Richard Chesler"",
""order"": 4,
""cast_id"": 8,
""profile_path"": ""/jghYiKdNkVehKpiVyE97AWrU9KQ.jpg""
}
]
}
}";
Movie movie = JsonConvert.DeserializeObject<Movie>(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：
Output:
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
