Question

我有一个json字符串：

{"GetOrderListResponse":
{"orderListResponse":
    {
    "orderDetails":
        [
        {"order":
            {
                "orderId":208,
                "legDetails":
                    {
                        "legNumber":1,
                        "symbolInfo":
                            {
                                "symbol":"CSCO"
                            }
                    }
            }
        },
        {"order":
            {
                "orderId":200,
                "legDetails":
                    [
                        {
                            "legNumber":1,
                            "symbolInfo":
                            {
                                "symbol":"IBM"
                            }
                        },
                        {
                            "legNumber":2,
                            "symbolInfo":
                            {
                                "symbol":"IBM",
                                "callPut":"CALL",
                                "expYear":2010,
                                "expMonth":4,
                                "expDay":17,
                                "strikePrice":115
                            }
                        }
                    ]
            }
        }
      ]
    }
}
}

我有对象

public class OrderListResponse
{
    public List<OrderDetail> orderDetails { get; set; }
}

public class OrderDetail
{
    public Order order { get; set; }
}

public class Order
{
    public long orderId { get; set; }
    public List<LegDetail> legDetails { get; set; }
}

public class LegDetail
{
    public long legNumber { get; set; }
    public Symbol symbolInfo { get; set; }
}

public class Symbol
{
    public string symbol { get; set; }
    public string callPut { get; set; }
    public int expYear { get; set; }
    public int expMonth { get; set; }
    public int expDay { get; set; }
    public int strikePrice { get; set; }
}

所以当我使用代码时：

var objectValue = JsonConvert.DeserializeObject<Dictionary<string, Dictionary<string, object>>>(jsonString);

var objectDeserialize = JsonConvert.DeserializeObject<OrderListResponse>(objectValue.Values.First()["orderListResponse"].ToString());

我收到错误消息：

无法将当前JSON对象（例如{＆＃34; name＆＃34;：＆＃34; value＆＃34;}）反序列化为类型System.Collections.Generic.List`1 [LegDetail]＆＃39;因为该类型需要JSON数组（例如[1,2,3]）才能正确反序列化。

有人能告诉我正确的代码吗？

Answer 1

第一顺序的logdetails不是数组......

"legDetails":
 {
    "legNumber":1,
    "symbolInfo":
     {
       "symbol":"CSCO"
     }
 }

应该如下：

"legDetails":
 [{
    "legNumber":1,
    "symbolInfo":
     {
       "symbol":"CSCO"
     }
 }]

所以现在问题是你想要反序列化一个有时可能是数组的json，有时可能代表一个对象。

查看另一个stackoverflow线程：Deserializing JSON when sometimes array and sometimes object

这可能有助于您解决问题。

您的JSON无效。它应该是：

{
   "GetOrderListResponse":{
      "orderListResponse":{
         "orderDetails":[
            {
               "order":{
                  "orderId":208,
                  "legDetails":[
                     {
                        "legNumber":1,
                        "symbolInfo":{
                           "symbol":"CSCO"
                        }
                     }
                  ]
               }
            },
            {
               "order":{
                  "orderId":200,
                  "legDetails":[
                     {
                        "legNumber":1,
                        "symbolInfo":{
                           "symbol":"IBM"
                        }
                     },
                     {
                        "legNumber":2,
                        "symbolInfo":{
                           "symbol":"IBM",
                           "callPut":"CALL",
                           "expYear":2010,
                           "expMonth":4,
                           "expDay":17,
                           "strikePrice":115
                        }
                     }
                  ]
               }
            }
         ]
      }
   }
}
