Question

I have a problem deserializing this JSON response

{
  "posts": {
    "Pippo": {
      "text": "text1",
      "link": "link1"
    },
    "Pluto": {
      "text": "text2",
      "link": "link2"
    }
  }
}

I’m using this model

public class postModel
{
    public string text { get; set; }
    public string link { get; set; }
}

public class postFields
{
    public postModel post { get; set; }
}

public class RootObject
{
    public Dictionary<string, postFields> posts { get; set; }
}

then I deserialize this way

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

then I stop. I cannot read values because I try this

foreach (var value in deserialized)
            {
                new postModel
                {
                    text = value.Value.post.text,
                    link = value.Value.post.link
                };
            }

Then I get NullReferenceException, because the name of JSON property isn’t “post” but Pippo, Pluto, etc.

Can someone help me?

Thanks to both of you; I solved this way:

var main = JObject.Parse(json);

        foreach (var mainRoute in main.Properties()) // this is "posts"
        {
            foreach (var subRoute in mainRoute.Values<JObject>().SelectMany(x => x.Properties())) // this is "Pippo", "Pluto"
            {
                var deserialized = JsonConvert.DeserializeObject<postModel>(subRoute.Value.ToString());

                new postModel
                {
                    text = deserialized.text,
                    link = deserialized.link
                };
            }
        }
