这里是 class 我正在尝试反序列化

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; }

    }

当我尝试转换为我的 class 的 List<> 时，我收到以下响应： 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]' 因为该类型需要 JSON 数组（例如 [1,2,3]）才能正确反序列化。要修复此错误，请将 JSON 更改为 JSON 数组（例如 [1,2,3]）或更改反序列化类型，使其成为普通的`

当我尝试只获取一个对象时，Class Equity 为空： var x2 = JsonConvert.DeserializeObject<Model.Qoutes.Qoute>(response);

我的理解是 public Dictionary<string, Equity> Equity { get; set; } 应该处理动态属性名称。我是否漏掉了一些明显的东西？

Answer 1

假设 json 有一个对象作为根，而不是数组，并且该对象没有 Equity 属性，就像您的 Quote 模型一样，它具有包含要映射到 Equity 的对象的属性，因此请尝试：

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