C# 反序列化根 JSON 未知密钥 [英] C# Deserialize Root JSON Unknown Keys

问题描述

我有一个这样的 JSON 并且必须反序列化它:

<代码>{0":{"foo_id":"xyz","bar_id":"abc",书": {0":{"title":"你好",作者":person_x"},1":{"title":"你好",作者":person_y"}},1":{"foo_id":"xyz","bar_id":"abc",书": {0":{"title":"你好",作者":person_a"},1":{"title":"再见",作者":person_b"}},"随机":"字符串","其他":"东西"}

更新:

由于您更改了问题中的原始 JSON，因此可以将第二个给定的 JSON 反序列化:

班级:

公共类RootObject{[JsonExtensionData]公共字典项目{得到;放;}[JsonProperty(随机")]公共字符串随机{获取；放;}[JsonProperty(其他")]公共字符串其他{得到;放;}}

反序列化:

var 结果 = JsonConvert.DeserializeObject(json);

I have a JSON like this and have to deserialize it:

{
  "0": {
    "foo_id":"xyz",
    "bar_id":"abc",
    "book": {
      "0": {
        "title":"hello",
        "author":"person_x"
      },
      "1": {
        "title":"hi",
        "author":"person_y"
      }
  },
  "1": {
    "foo_id":"xyz",
    "bar_id":"abc",
    "book": {
      "0": {
        "title":"hello",
        "author":"person_a"
      },
      "1": {
        "title":"bye",
        "author":"person_b"
      }
  },
  "random":"string",
  "other":"thing"
}

Similar to this question, except the answer given doesn't work, because I don't have the luxury of creating a class like this

public class RootObject
{
    public Dictionary<string, Object> Objects {get; set;}
}

If I do than the Objects field is null after deserialization.

Both the root object and book object are dynamic.

Any other approaches would be appreciated, Thanks in advance.

解决方案

Because the JSON you have does not contains a RootObject that holds a dictionary, you can deserialize straight into a Dictionary like so:

Class:

public class Item
{
    [JsonProperty("foo_id")]
    public string FooId { get; set; }

    [JsonProperty("bar_id")]
    public string BarId { get; set; }
}

Deserialize:

var result = JsonConvert.DeserializeObject<Dictionary<string, Item>>(json);

Result:

Update:

Since you have changed the original JSON in your question, the second given JSON can be deserialized as so:

Class:

public class RootObject
{
    [JsonExtensionData]
    public Dictionary<string, JToken> Items { get; set; }

    [JsonProperty("random")]
    public string Random { get; set; }

    [JsonProperty("other")]
    public string Other { get; set; }
}

Deserialize:

var result = JsonConvert.DeserializeObject<RootObject>(json);
