解析嵌套的 json 在对象中返回 null

Question

我有以下json。{    "room1": {        "first": "id1",        "second": "id2",        "third": "id3"    },    "room2": {        "first": "id1",        "second": "id2",        "third": "id3"    }}我正在尝试对这两个类进行反序列化。public class Streams    {        [JsonProperty("first")]        public string first { get; set; }        [JsonProperty("second")]        public string second { get; set; }        [JsonProperty("third")]        public string third { get; set; }    }    public class Room    {            public string room { get; set; }            public Streams streams { get; set; }    }我当前的代码很简单：Rooms r = JsonConvert.DeserializeObject<Rooms>(jsonstring);我知道我的 json 字符串有多个房间，但是如果我添加 List 它会引发异常。上面的这条线通过了，但是我得到了房间和流的空值。我还尝试将 Rooms 类构建为Dictionary<string, Streams> d { get; set; }这没有引发异常，但仍然返回 null。编辑：我把 json 改成这样，现在解析得很好。[{    "room":"room1",    "first": "id1",    "second": "id2",    "third": "id3"},{    "room":"room1",    "first": "id1",    "second": "id2",    "third": "id3"}]

Answer 1

你的类对于这个对象是错误的

public class JsonClass

{

    public RoomClass room1 {get; set;}

    public RoomClass room2 {get; set;}

}

public class RoomClass

{

    [JsonProperty("first")]

    public string first { get; set; }

    [JsonProperty("second")]

    public string second { get; set; }

    [JsonProperty("third")]

    public string third { get; set; }

}

然后

var result = JsonConvert.DeserializeObject<JsonClass>(jsonstring);

编辑：OP表示会有很多房间

var result = JsonConvert.DeserializeObject<IDictionary<string, RoomClass>>(jsonstring);

Answer 2

public class Rooms

{

        public Streams room1{ get; set; }

        public Streams room2{ get; set; }

}

Rooms r = JsonConvert.DeserializeObject<Rooms>(jsonstring);
