使用 JSON.Net 反序列化器反序列化动态 JSON

Question

我正在尝试扩展此处给出的 JSON.net 示例尝试遵循http://james.newtonking.com/projects/json/help/CustomCreationConverter.html 中的JSON.net 示例来反序列化对象。

班级结构：

public class Rootobject
{
public int took { get; set; }
public bool timed_out { get; set; }
public _Shards _shards { get; set; }
public Hits hits { get; set; }
}

public class _Shards
{
public int total { get; set; }
public int successful { get; set; }
public int failed { get; set; }
}

public class Hits
{
public int total { get; set; }
public float max_score { get; set; }
public Hit[] hits { get; set; }
}

public class Hit
{
public string _index { get; set; }
public string _type { get; set; }
public string _id { get; set; }
public float _score { get; set; }
public Inner_Hits inner_hits { get; set; }
}

public class Inner_Hits
{
public Testp11 testp11 { get; set; }
public Testp10 testp10 { get; set; }
}

public class Testp11
{
public Hits1 hits { get; set; }
}

public class Hits1
{
public int total { get; set; }
public float max_score { get; set; }
public Hit1[] hits { get; set; }
}

public class Hit1
{
public string _index { get; set; }
public string _type { get; set; }
public string _id { get; set; }
public _Nested _nested { get; set; }
public float _score { get; set; }
public _Source _source { get; set; }
}

public class _Nested
{
public string field { get; set; }
public int offset { get; set; }
public _Nested1 _nested { get; set; }
}

public class _Nested1
{
public string field { get; set; }
public int offset { get; set; }
public _Nested2 _nested { get; set; }
}

public class _Nested2
{
public string field { get; set; }
public int offset { get; set; }
}

public class _Source
{
public string pname { get; set; }
public Value[] values { get; set; }
}

public class Value
{
public string pid { get; set; }
public string[] val { get; set; }
}

public class Testp10
{
public Hits2 hits { get; set; }
}

public class Hits2
{
public int total { get; set; }
public float max_score { get; set; }
public Hit2[] hits { get; set; }
}

public class Hit2
{
public string _index { get; set; }
public string _type { get; set; }
public string _id { get; set; }
public _Nested3 _nested { get; set; }
public float _score { get; set; }
public _Source1 _source { get; set; }
}

public class _Nested3
{
public string field { get; set; }
public int offset { get; set; }
public _Nested4 _nested { get; set; }
}

public class _Nested4
{
public string field { get; set; }
public int offset { get; set; }
public _Nested5 _nested { get; set; }
}

public class _Nested5
{
public string field { get; set; }
public int offset { get; set; }
}

public class _Source1
{
public string pname { get; set; }
public Value1[] values { get; set; }
}

public class Value1
{
public string pid { get; set; }
public string[] val { get; set; }
}

在我的 json doc 调用函数中：

  string json = "{  \"took\": 2,  \"timed_out\": false,  \"_shards\": {    \"total\": 5,    \"successful\": 5,    \"failed\": 0  },  \"hits\": {    \"total\": 4,    \"max_score\": 8.225408,    \"hits\": [      { \"_index\": \"dev28\", \"_type\": \"Index_Type1\", \"_id\": \"user_2\", \"_score\": 8.225408, \"inner_hits\": { \"testp11\": { \"hits\": {              \"total\": 1, \"max_score\": 5.816241, \"hits\": [ { \"_index\": \"dev28\",                  \"_type\": \"Index_Type1\",                  \"_id\": \"user_2\",                  \"_nested\": {  \"field\": \"doc\",\"offset\": 0, \"_nested\": { \"field\": \"roles\", \"offset\": 0, \"_nested\": { \"field\": \"permissions\", \"offset\": 0 } } }, \"_score\": 5.816241, \"_source\": { \"pname\": \"Permission1\", \"values\": [ { \"pid\": \"S1_P1\", \"val\": [ \"V12\", \"V11\" ] } ] } } ] } },\"testp10\": { \"hits\": { \"total\": 1, \"max_score\": 5.816241, \"hits\": [ { \"_index\": \"dev28\", \"_type\": \"Index_Type1\",\"_id\": \"user_2\", \"_nested\": { \"field\": \"doc\", \"offset\": 0, \"_nested\": {\"field\": \"roles\", \"offset\": 0, \"_nested\": { \"field\": \"permissions\", \"offset\": 0}} }, \"_score\": 5.816241, \"_source\": {\"pname\": \"Permission2\",\"values\": [ {\"pid\": \"S1_P1\", \"val\": [\"V12\",\"V11\" ]} ] } } ] } } } }]} }";            

            dynamic objResultElasticData = (Rootobject)Newtonsoft.Json.JsonConvert.DeserializeObject(json, typeof(Rootobject));

在上面的类中，我有一个类为“公共类 Inner_Hits”，其中数据可以是动态的，具有不同的名称。 目前它有“Testp11”和“Testp10”，也可以有与“Testp11”具有相同层次结构的“Testp12”，有人可以告诉我如何实现这种动态行为。

希望有人能指出我正确的方向。

问候， 杰克

如果您的类属性正在动态更改，我认为您不能使用此解析器。 看看这个。 这可能对你有帮助。 动态JSon解析器

您可以利用 Json.NET 将字典序列化为JSON 名称/值对对象的能力来定义您的inner_hits ，如下所示：

    public Dictionary<string, InnerHit> inner_hits { get; set; }

您还应该组合由自动代码生成器创建的各种重复类。 一个完整的实现将是：

public class Shards
{
    public int total { get; set; }
    public int successful { get; set; }
    public int failed { get; set; }
}

public class Nested
{
    public string field { get; set; }
    public int offset { get; set; }
    [JsonProperty(DefaultValueHandling = DefaultValueHandling.Ignore)] // Do not write the null value
    public Nested _nested { get; set; }
}

public class Value
{
    public string pid { get; set; }
    public List<string> val { get; set; }
}

public class Source
{
    public string pname { get; set; }
    public List<Value> values { get; set; }
}

public class Hit2
{
    public string _index { get; set; }
    public string _type { get; set; }
    public string _id { get; set; }
    public Nested _nested { get; set; }
    public double _score { get; set; }
    public Source _source { get; set; }
}

public class Hits2
{
    public int total { get; set; }
    public double max_score { get; set; }
    public List<Hit2> hits { get; set; }
}

public class InnerHits
{
    public Hits2 hits { get; set; }
}

public class Hit
{
    public string _index { get; set; }
    public string _type { get; set; }
    public string _id { get; set; }
    public double _score { get; set; }
    public Dictionary<string, InnerHits> inner_hits { get; set; }
}

public class Hits
{
    public int total { get; set; }
    public double max_score { get; set; }
    public List<Hit> hits { get; set; }
}

public class RootObject
{
    public int took { get; set; }
    public bool timed_out { get; set; }
    public Shards _shards { get; set; }
    public Hits hits { get; set; }
}

另外，这里不需要使用dynamic ，你可以这样做：

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

并获得静态检查正确性的优势。
