JSON.Net - 无法将当前json对象(例如{"name":"value"})反序列化为类型'system.collections.generic.list`1

Question

我有一个类似的JSON

{
  "40": {
    "name": "Team A vs Team B",
    "value": {
      "home": 1,
      "away": 0
    }
  },
  "45": {
    "name": "Team A vs Team C",
    "value": {
      "home": 2,
      "away": 0
    }
  },
  "50": {
    "name": "Team A vs Team D",
    "value": {
      "home": 0,
      "away": 2
    }
  }
}

所以它是一种匹配列表.我有课程将其反序列化为:

public class Match
{
    [JsonProperty(PropertyName = "name")]
    public string Name { get; set; }
    [JsonProperty(PropertyName = "value")]
    public Value Values { get; set; }
}

public class Value
{
    [JsonProperty(PropertyName = "home")]
    public int Home { get; set; }
    [JsonProperty(PropertyName = "away")]
    public int Away { get; set; }
}

我试图像这样反序列化json:

var mList= JsonConvert.DeserializeObject<List<Match>>(jsonstr);

但我得到例外:

无法将当前JSON对象(例如{"name":"value"})反序列化为类型'System.Collections.Generic.List`1 [ClassNameHere]',因为该类型需要JSON数组(例如[1,2,3] )正确反序列化.

如果我改变代码如:

var mList= JsonConvert.DeserializeObject(jsonstr);

然后它序列化但不作为列表,作为对象.我怎样才能解决这个问题？

Answer 1

在这种情况下,您应该问Deserializer IDictionary<string, Match>

var mList= JsonConvert.DeserializeObject<IDictionary<string, Match>>(jsonstr);

并且第一个元素将具有键"40"并且值将是Match实例

换句话说这部分:

"40": {
    "name": "Team A vs Team B",
    "value": {
      "home": 1,
      "away": 0
    }

将导致KeyValuePair:

key - "40"
value - Match { Name = "Team",  ... }
