c# - 无法将类型 'Newtonsoft.Json.Linq.JObject' 转换为复杂类型

Question

我有如下的json，

{
  "H": "Macellum",
  "M": "Receive",
  "A": [
    {
      "CustomerId": "172600",
      "OrderId": "69931",
      "OrderStatus": "E0",
      "Buy": "A"
    }
  ]
}

和复杂类型

public class OrderStats
{
    public string CustomerId { get; set; }
    public string OrderId { get; set; }
    public string OrderStatus { get; set; }
    public string Buy { get; set; }
}

我正在尝试如下类型转换，

dynamic obj = JsonConvert.DeserializeObject<dynamic>(message);
OrderStats info = (OrderStats)obj.A[0]; //exception
OrderStats info = obj.A[0] as OrderStats; //info is null

但是报错如下

Cannot convert type 'Newtonsoft.Json.Linq.JObject' to OrderStatus

Answer 1

这个怎么样？

var str = "YOUR_JSON_HERE";
var obj = JsonConvert.DeserializeObject<dynamic>(str);
OrderStats info = ((JArray)obj.A)[0].ToObject<OrderStats>();
