json deserialization to C# with dynamic keys [duplicate]

Question

The response to my web request coming as the following (not under my control):

{
"nasdaq_imbalance": 
{
    "name": "nasdaq_imbalance", 
    "group": "Market Data", 
    "description": null
},
"DXOpen IM": 
{
    "name": "DXOpen IM", 
    "group": "Daily",
    "description": null
}, 
"Float Shares": 
{
    "name": "Float Shares", 
    "group": "Daily", 
    "description": null
},

}

Somehow, I need to deserialize that into C# object that contains a list of objects... Basically I need a list of objects like that:

public class Dataset    {
    public string name { get; set; } 
    public string group { get; set; } 
    public string description { get; set; } 
}

You can go to quicktype.io and paste your json in there, it will generate the classes, and the deser code, and even comments to tell you how to use it — Caius Jard

@CaiusJard that probably isn't the best duplicate to use, considering JavaScriptSerializer is deprecated. — David L

That's the trouble with C# JSON Qs.. too many duplicates.. stackoverflow.com/questions/25052293/… — Caius Jard

@CaiusJard The issue is with SO. It's easier for me to type a short answer like that than to try find a duplicate and hope a moderator actually looks at it when I flag it. — Charlieface

A better duplicate is How can I parse a JSON string that would cause illegal C# identifiers?. The answers there say to 1) Use a dictionary if the root object property names are not fixed; 2) If the root object property names are fixed, use a root object with properties marked with JsonPropertyAttribute attributes, e.g. [JsonProperty("DXOpen IM")] public Dataset DXOpenIM { get; set; }. — dbc

If you are using Json.NET, you can use JsonConvert.DeserializeObject<Dictionary<string, Dataset>>(json) and the keys of the dictionary will be nasdaq_imbalance, DXOpen IM, Float Shares

I will try shortly, so far it is the most promising solution posted here...BTW, I was searching here A to Z and could not find similar structure since it is kinda pseudo-jason

Great thinking Charlieface! From the Dictionary I can easily make the list...
