And here is the class I am trying to deserialize

public class Qoute
    {
        public Dictionary<string, Equity> Equity { get; set; }
    }

    public class Equity
    {
        public string assetType { get; set; }
        public string assetMainType { get; set; }
        public string cusip { get; set; }
        public string symbol { get; set; }
        public string description { get; set; }
        public float bidPrice { get; set; }
        public int bidSize { get; set; }
        public string bidId { get; set; }
        public float askPrice { get; set; }
        public int askSize { get; set; }
        public string askId { get; set; }
        public float lastPrice { get; set; }
        public int lastSize { get; set; }
        public string lastId { get; set; }
        public float openPrice { get; set; }
        public float highPrice { get; set; }
        public float lowPrice { get; set; }
        public string bidTick { get; set; }
        public float closePrice { get; set; }
        public float netChange { get; set; }
        public int totalVolume { get; set; }
        public long quoteTimeInLong { get; set; }
        public long tradeTimeInLong { get; set; }
        public float mark { get; set; }
        public string exchange { get; set; }
        public string exchangeName { get; set; }
        public bool marginable { get; set; }
        public bool shortable { get; set; }
        public float volatility { get; set; }
        public int digits { get; set; }
        public float _52WkHigh { get; set; }
        public float _52WkLow { get; set; }
        public float nAV { get; set; }
        public float peRatio { get; set; }
        public float divAmount { get; set; }
        public float divYield { get; set; }
        public string divDate { get; set; }
        public string securityStatus { get; set; }
        public float regularMarketLastPrice { get; set; }
        public int regularMarketLastSize { get; set; }
        public float regularMarketNetChange { get; set; }
        public long regularMarketTradeTimeInLong { get; set; }
        public float netPercentChangeInDouble { get; set; }
        public float markChangeInDouble { get; set; }
        public float markPercentChangeInDouble { get; set; }
        public float regularMarketPercentChangeInDouble { get; set; }
        public bool delayed { get; set; }
        public bool realtimeEntitled { get; set; }
    }




}

When I try to convert to a List<> of my class I get this response: var x= JsonConvert.DeserializeObject<List<Model.Qoutes.Qoute>>(response); Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List1[TDAPI.Model.Qoutes.Qoute]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly. To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal`

When I try to just get a single object, the Class Equity is null: var x2 = JsonConvert.DeserializeObject<Model.Qoutes.Qoute>(response);

My understanding is that public Dictionary<string, Equity> Equity { get; set; } should have taken care of a dynamic property name. Am I missing something obvious?

Provided json has an object as a root, not an array, and this object does not have Equity property, as your Quote model does, it has properties containing objects you want to map to Equity so try:

var result = JsonConvert.DeserializeObject<Dictionary<string, Equity>>(response);

Oh - I see. My issue was I was serializing the wrong class. I was assuming since the class Qoute had public Dictionary Equity { get; set; } it would deserialize into a list at that level – user1257758 Jan 29 '22 at 20:50
In fact, I should have named my Equity class Qoute if that was my intention – user1257758 Jan 29 '22 at 20:51
