How to deserialise this nested json response and save the the array values with multiple Jobjects in Unity

I have little to no experience in JSON and I am stuck with a problem. Any help is appreciated.

I want to access specifically the names’ values from the additionalInformation array.

JSON Response:

    {
    "statusCode": 200,
    "version": 1,
    "jsonData": [
        {
            "additionalInformation": [
                {
                    "id": "XXX94XXXX9xxXx_xxxXXXX",
                    "name": "xxxx xxx x xxxxxxxx"
                },
                {
                    "id": "0xXXxcXxv5PQqT$6i2zLgV",
                    "name": "xxx xxxxxxxx"
                },
                {
                    "id": "11Krt_our2rPCPqJ_2fKZR",
                    "name": "xxx xxxxxxxx xx"
                },
                {
                    "id": "2jYw4IyBP8KuozM_ej7DGf",
                    "name": "xxxxxxx 1"
                },
                {
                    "id": "3B8O805wL1ufabHMz1Je3v",
                    "name": "xxxxxxx 2"
                },
                {
                    "id": "0FVKUYZkvFaxd_OQUiyPBZ",
                    "name": "xxxxxxx"
                },
                {
                    "id": "3O41QFd0573QQvFco5zUUP",
                    "name": "Xxxxxxxxx"
                }
            ],
            "type": 0
        }
    ],
    "errorMessages": [],
    "warningMessages": [],
    "informationMessages": []
}

Model:

public class CFunctions
{
    public int statusCode { get; set; }
    public int version { get; set; }

    public List<PFunctions>[] jsonData { get; set; }

    public List<string> errorMessages { get; set; }

    public List<string> warningMessages { get; set; }

    public List<string> informationMessages { get; set; }

    /*public CFunctions()
    {
        jsonData = new List<PFunctions>();
    }*/
   }

[Serializable]
public class PFunctions 
{
    public List<PAdditionalInfo>[] additionalInformation { get; set; }

    public int type { get; set; }

    /*public PFunctions()
    {
        additionalInformation = new List<PAdditionalInfo>();
    }*/
}

[Serializable]
public class PAdditionalInfo 
{
   public  Guid id { get; set; }

   public string name { get; set; }
}

Deserialisation

var request = UnityWebRequest.Get(baseurl);
var operation = request.SendWebRequest();
var jsonResponse = request.downloadHandler.text;
List<CFunctions>[] PFunctionsList = JsonConvert.DeserializeObject<List<CFunctions>[]>(jsonResponse);

Error:

Cannot deserialize the current JSON object into type ‘System.Collections.Generic.List`1[CFunctions][]’ because the type requires a JSON array to deserialize correctly.
To fix this error either change the JSON to a JSON array or change the deserialized type so that it is a normal .NET type that can be deserialized from a JSON object.
JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.
Path ‘statusCode’, line 1, position 14.
UnityEngine.Debug:Log(Object)

What I tried

The error pertains even when I changed List<PAdditionalInfo> to List<PAdditionalInfo>[]

I am not sure how to use JsonObjectAttribute and if it is the best way.

>Solution :

You’ve declared an array of List<T> in the models, eg List<PAdditionalInfo>[]. The json represents single arrays, not nested. You can fix that by choosing one or the other (I decided to use List<> but array is valid too):

public class PFunctions 
{
    public List<PAdditionalInfo> additionalInformation { get; set; }  // removed []
    ...
}

public class CFunctions
{
    public int statusCode { get; set; }
    public int version { get; set; }

    public List<PFunctions> jsonData { get; set; }    // removed []
    ...
}

The class you’re deserializing to is incorrect. Deserialize to the correct type (which is CFunctions not List<CFunctions>[]):

CFunctions cFunctions = JsonConvert.DeserializeObject<CFunctions>(json);
