Deserializing no array json object to dictionary in c#

Question

I am trying to deserilaize json to a c# class. I am not sure how I can get the ErrorContent into Dictionary of key value pair? Since Error Content is not an array, can I still convert it to Dictionary?

When I try below code, I keep getting ErrorContent as null..

    var response = JsonConvert.DeserializeObject<SearchResponse>(jsonResponse);

The class Search Response looks like

public class SearchResponse
{
    public ErrorContent Errors { get; set; }
}

public class ErrorContent
{
    public Dictionary<int, string> Errors { get; set; } = new Dictionary<int, string>();
}

Sample json looks like

    {   
    "statusCode": 1233,   "status": "ERROR",   "payloadType": "ERROR", "payload": {
    "ErrorContent":{
       "101": "Value cannot be null",
       "102": "Value should always be integer"
    }}}

You're missing the `payload` property, of which `ErrorContent` is a child. It's also named `ErrorContent` in the JSON, so you likely want your C# property to be named the same. Use a service like https://jsonutils.com/ to convert your JSON to C# classes. — Heretic Monkey, Jun 12 '20 at 20:35

You can decorate your model with correct JSON properties. Response contains `payload` property, which has `ErrorContent` that can be parsed to `Dictionary` — Pavel Anikhouski, Jun 12 '20 at 20:38

Change your model like this. Your JSON and C# model are not correctly binding due to wrong models

  public class SearchResponse
    {
        [JsonProperty("payload")]
        public PayLoad PayLoad { get; set; }
    }

    public class PayLoad
    {
        public Dictionary<int, string> ErrorContent { get; set; }

    }

Binding Steps

First your model will look for SearchResponse class
Then it will look for a class named payload
Then it will look for a dictionary with name ErrorContent

prob here is that I see all the values except for the dictionary.. Its always null. SO I am not sure if this can ever be converted to dictionary since it doesnt have [ ]?? – challengeAccepted Jun 12 '20 at 23:27
I have tried it by myself and it is working. No need to have [] for the dictionary – Hammad Shabbir Jun 13 '20 at 18:05
