JSON 反序列化，其中部分就像字典

Question

我有来自 API 的 JSON，如下所示：

{
    "GetJsonResult": {
        "EntityName": "account",
        "FailureReason": "",
        "Counter": 0,
        "MoreRecords": false,
        "OptionSetName": "sic_organisationtitlewad",
        "Success": true,
        "OptionSetsClean": "[{\"Mr\":100000000},{\"Mrs\":100000003},{\"Miss\":100000002},{\"Ms\":100000004},{\"Prof\":100000001},{\"Sir\":907510000}]",
        "OptionSets": [
            {
                "Mr": 100000000
            },
            {
                "Mrs": 100000003
            },
            {
                "Miss": 100000002
            },
            {
                "Ms": 100000004
            },
            {
                "Prof": 100000001
            },
            {
                "Sir": 907510000
            }
        ],
        "Entities": null
    }
}

我有一个这样的类定义：

public class GetJsonResult
{
    [JsonProperty("EntityName")]
    public string EntityName { get; set; }

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

    [JsonProperty("Counter")]
    public int Counter { get; set; }

    [JsonProperty("MoreRecords")]
    public bool MoreRecords { get; set; }

    [JsonProperty("OptionSetName")]
    public string? OptionSetName { get; set; }

    [JsonProperty("Success")]
    public bool Success { get; set; }

    [JsonProperty("OptionSetsClean")]
    public Dictionary<string, int>? OptionSetsClean { get; set; }

    [JsonProperty("OptionSets")]
    public object OptionSets { get; set; }

}

并使用“JsonConvert.DeserializeObject”来处理数据。

我想获取“OptionSetsClean”或“OptionSets”中的数据（它们包含相同的数据）以转换为字典或列表之类的内容。但是，我想不出一种方法来做到这一点。

作为一个选项，您可以使用自定义转换器来转换为列表 如果需要，您可以扩展 ot 并转换为字典。 我把你的 json 存储到文件中。 另外，您还需要再包装一个对象。

void Main()
{
    var j = File.ReadAllText("C:\\1\\test.json");
    var x = JsonConvert.DeserializeObject<Root>(j).Dump();
}

public class Root
{
    public GetJsonResult GetJsonResult { get; set; }
}

public class GetJsonResult
{
    public string EntityName { get; set; }
    public string FailureReason { get; set; }
    public int Counter { get; set; }
    public bool MoreRecords { get; set; }
    public string OptionSetName { get; set; }
    public bool Success { get; set; }
    [JsonConverter(typeof(StringConverter<Dictionary<string,int>>))]
    public List<JObject> OptionSetsClean { get; set; }
    public List<JObject> OptionSets { get; set; }
    public string Entities {get;set;}

}

public class StringConverter<T> : JsonConverter
{
    public override bool CanConvert(Type objectType)
    {
        throw new NotImplementedException();
    }

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue, JsonSerializer serializer)
    {
        var res = JsonConvert.DeserializeObject<List<JObject>>(reader.Value.ToString());
        return  res;
        
    }

    public override void WriteJson(JsonWriter writer, object value, JsonSerializer serializer)
    {
        throw new NotImplementedException();
    }
}

结果
