C# JsonConvert 捕捉数据到对象错误

问题描述

我想捕捉对象的响应数据

我想声明instant_price 默认使用instant_price_info 来捕获数组内部的数据，但是我尝试了错误我该怎么办

我想做这个怎么办

    public class test
    {
        public test_info test_content { get; set; }

        public test()
        {
            test_content = new test_info();
        }
    }

    public class test_info
    {
        public string info1 { get; set; }
        public string info2 { get; set; }
    }

我创建了 Instant_price 类

    public class instant_price
    {
        public Array msgArray { get; set; }

        //public instant_price()
        //{
        //    msgArray = new Array() { List<instant_price_info> };
        //}
    }

    public class instant_price_info
    {
        public string c { get; set; } 
        public string n { get; set; } 
        public string d { get; set; } 
        public string t { get; set; } 
        public string o { get; set; } 
        public string h { get; set; } 
        public string l { get; set; } 
        public string z { get; set; } 
        public string tv { get; set; } 
        public string v{ get; set; } 
        public string a{ get; set; }
        public string b { get; set; } 
    }

这个数据

{
  "msgArray": [
    {
      "tv": "-","ps": "4","pz": "71.3000","fv": "1","oa": "71.1000","ob": "71.0000","c": "4126","d": "20210624","ch": "4126.tw","ot": "14:30:00","g": "7_12_27_15_53_","mt": "000000","ov": "1440","h": "71.3000","i": "22","it": "12","oz": "71.0000","l": "70.8000","t": "13:33:00","y": "70.8000","z": "71.3000","ts": "0"
    }
  ],"userDelay": 5000,"rtmessage": "OK","cachedAlive": 737684
}

当我捕获响应数据时

instant_price stock = JsonConvert.DeserializeObject<instant_price>(responseResult);

我收到此错误代码

Newtonsoft.Json.JsonSerializationException: '无法创建 System.Array 类型的实例。类型是接口或抽象类，不能被实例化。路径 'msgArray'，第 25 行，位置 13。'

解决方法

由于 JSon 结果是一个数组，您将需要使用 list。

list stockList = JsonConvert.DeserializeObject>(responseResult);
