Question

我知道这个问题已被多次询问过。但我仍然是一个新手，似乎我无法反序列化我从get请求获得的json数组。

这是我的代码：

Activity.cs

var getResponse = RequestClass.GetChargingPointsData(pathUrl, currentToken);
            System.Diagnostics.Debug.WriteLine("My GETresponse: " + getResponse);

            //CharchingPointClass getCPDetail = JsonConvert.DeserializeObject<CharchingPointClass> (getResponse);
            //var getCPDetail = JsonConvert.DeserializeObject<CharchingPointClass> (getResponse);

            //List<CharchingPointClass> getCPDetail = (List<CharchingPointClass>)JsonConvert.DeserializeObject(getResponse, typeof(List<CharchingPointClass>));


            CharchingPointClass result = (CharchingPointClass)JsonConvert.DeserializeObject(getResponse, typeof(CharchingPointClass));
            System.Diagnostics.Debug.WriteLine("My longitudes: " + result.lat);

评论中的代码对我来说也不起作用......

CharchingPointClass.cs

public class CharchingPointClass
{

    public string _id { get; set; }
    public double price { get; set; }
    public string type { get; set; }
    public string model { get; set; }
    public string modelID { get; set; }
    public double lat { get; set; }
    public double lng { get; set; }
    public string address { get; set; }
    public int __v { get; set; }
    public string modified_at { get; set; }
    public string created_at { get; set; }



    public CharchingPointClass ()
    {
    }
}

更新： JSON

[

    "_id": "56d98506a7012ee0001bc42c",
    "price": 135.5,

    "created_at": "2016-03-04T13:12:48.706Z"
}

错误讯息：

{Newtonsoft.Json.JsonSerializationException：无法将当前JSON对象（例如{＆＃34; name＆＃34;：＆＃34; value＆＃34;}）反序列化为类型＆＃39; iChargeClassTest.CharchingPointClass＆＃39;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]），或者将反序列化类型更改为实现集合接口（例如ICollection，IList）的数组或类型，例如可以从中反序列化的List JSON array.JsonObjectAttribute也可以添加到类型中以强制它从JSON数组反序列化。}

有人可以帮我解决这个问题吗？

非常感谢帮助：）

Answer 1

尝试使用以下类来序列化。

public class CarchingPointClass
{
    public string _id { get; set; }
    public double price { get; set; }
    public string type { get; set; }
    public string model { get; set; }
    public string modelID { get; set; }
    public double lat { get; set; }
    public double @long { get; set; }
    public string address { get; set; }
    public int __v { get; set; }
    public string modified_at { get; set; }
    public string created_at { get; set; }
}

然后使用以下行序列化。

var result=JsonConvert.DeserializeObject<List<CarchingPointClass>>(inputString)

Answer 2

您必须使用该行进行反序列化。

  var result=JsonConvert.DeserializeObject<List<CarchingPointClass>>(inputString)

班级将

  public class CarchingPointClass
  {
   public string _id { get; set; }
   public double price { get; set; }
   public string type { get; set; }
   public string model { get; set; }
   public string modelID { get; set; }
   public double lat { get; set; }
   [JsonProperty("long")]
   public double lng { get; set; }
   public string address { get; set; }
   public int __v { get; set; }
   public string modified_at { get; set; }
   public string created_at { get; set; }
 }

无法反序列化json数组
