How I should deserialized this object correctly?

Question

I use an API that return a collection of company symbols with some properties but I don't know how should I deserialize it

{
    "A": {
        "advanced-stats": {
            "prop1": 0.198791,
            "prop2": 16.59,
            "prop3": 12.44,
        }
    },
    "AA": {
        "advanced-stats": {
            "prop1": 0.198791,
            "prop2": 16.59,
            "prop3": 12.44,
        }
    },
    "AAAU": {
        "advanced-stats": {
            "prop1": 0.198791,
            "prop2": 16.59,
            "prop3": 12.44,        
        }
    }
}

This might help you to get a starting point: http://json2csharp.com/ — Stefan, Nov 22 '19 at 09:13
I already try this method, also on other sites, but nothing match — Filip Laurentiu, Nov 22 '19 at 09:14
@Stefan You probably don't want to use external web applications as you might store sensitive data somewhere else. You should refrain from using those and OP is asking for a specific C# solution when looking at the tags. — Barrosy, Nov 22 '19 at 09:14
@Barrosy: well, I meant just to get started with the C# modeling... anyhow, OP seems to already have tried that. — Stefan, Nov 22 '19 at 09:15

Dictionary (keys = A, AA etc) of Objects containing a property (advanced-stats) of type List/Array of “some pair type” would be a start.. and transform in whatever local model is appropriate. — user2864740, Nov 22 '19 at 09:19
@user2864740 It seams that this is the way. I also try this method but in a wrong way. Thank you very much ! — Filip Laurentiu, Nov 22 '19 at 09:29

You can model the JSON using the following classes:

public class AdvancedStats
{
    public double Prop1 { get; set; }
    public double Prop2 { get; set; }
    public double Prop3 { get; set; }
}

public class AdvancedRoot
{
    [JsonProperty("advanced-stats")]
    public AdvancedStats AdvancedStats { get; set; }
}

Since the JSON keys have different names, you can model this as Dictionary<string, AdvancedRoot>. Then to deserialize (using Newtonsoft.Json):

var results = JsonConvert.DeserializeObject<Dictionary<string, AdvancedRoot>>(json);
