Deserializing JSON string with dynamic keys

Question

I have a JSON string with some key is dynamic.

{
"status": {
    "code": "200",
    "message": "OK"
},
"total": 1,
"results": [
    {
        "leader": "00689cam a2200217 a 4500",
        "fields": [
            {
                "020": {
                    "ind2": "#",
                    "ind1": "#",
                    "subfields": [
                        {
                            "a": "9786041092587"
                        },
                        {
                            "c": "200000đ"
                        }
                    ]
                }
            },
            {
                "041": {
                    "ind2": "#",
                    "ind1": "0",
                    "subfields": [
                        {
                            "a": "vie"
                        }
                    ]
                }
            }
        ]
    }
]}

In there, "020", "041", "a", "c" are dynamic keys. I am trying to deserialize it into a C# object model:

[DataContract]
public class Data
{
    [DataMember]
    public Status status { get; set; }
    [DataMember]
    public int total { get; set; }
    [DataMember]
    public List<Result> Results { get; set; }
}

[DataContract]
public class Status
{
    [DataMember]
    public string code { get; set; }
    [DataMember]
    public string message { get; set; }
}

[DataContract]
public class Result
{
    [DataMember]
    public string leader { get; set; }
    [DataMember]
    public List<Field> fields { get; set; }
}

[DataContract]
public class Field
{
    [DataMember]
    List<Tag> Tags { get; set; }
}

[DataContract]
public class Tag
{
    [DataMember]
    public string ind1 { get; set; }
    [DataMember]
    public string ind2 { get; set; }
    [DataMember]
    public List<subField> subfields { get; set; }
}

[DataContract]
public class subField
{
    [DataMember]
    public List<sCode> Codes { get; set; }
}

[DataContract]
public class sCode
{
    [DataMember]
    public string key { get; set; }
    [DataMember]
    public string value { get; set; }
}

I am deserializing the JSON format with the code below:

string strJson = f["dataJson"].ToString();
var deserializedData = JsonConvert.DeserializeObject<Dictionary<string, Data>>(strJson);

I am sure that I'm wrong something here but I can't find them. Any help would be really appreciated! Thanks so much!

Pls try my codes below.

public void hello() {
     var jsonStr = $@"{{
""total"": 1,
""results"": [
    {{
        ""leader"": ""00689cam a2200217 a 4500"",
        ""fields"": [
            {{
                ""020"": {{
                    ""ind2"": ""#"",
                    ""ind1"": ""#"",
                    ""subfields"": [
                        {{
                            ""a"": ""9786041092587""
                        }},
                        {{
                            ""c"": ""200000đ""
                        }}
                    ]
                }}
            }},
            {{
                ""041"": {{
                    ""ind2"": ""#"",
                    ""ind1"": ""0"",
                    ""subfields"": [
                        {{
                            ""a"": ""vie""
                        }}
                    ]
                }}
            }}
        ]
    }}
]}}";
    Data res = JsonConvert.DeserializeObject<Data>(jsonStr);
}
        
        
public class Data {
    public int total { get; set; }
    public List<Result> Results { get; set; }

}

public class Result
{
    public string leader { get; set; }
    public List<Dictionary<string, Tag>> fields { get; set; }
}

public class Tag
{
    public string ind1 { get; set; }
    public string ind2 { get; set; }
    public List<Dictionary<string, string>> subfields { get; set; }
}

And here's my test result.
