无法反序列化json数组 [英] Can't deserialize json array

问题描述

我知道这个问题已经问过很多次了.但是我仍然是一个新手，似乎我无法反序列化从get请求获得的json数组.

I know this question has been asked many times. But i'm still a newbie and it seems like I can't deserialize the json array I got from a get request.

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);

注释中的代码也不适用于我...

The codes in comment also didn't work for me...

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

错误消息:

{Newtonsoft.Json.JsonSerializationException:无法将当前JSON对象(例如{"name":"value"})反序列化为类型'iChargeClassTest.CharchingPointClass'，因为该类型需要JSON数组(例如[1,2,3 ])正确反序列化. 要解决此错误，可以将JSON更改为JSON数组(例如[1,2,3])，也可以将反序列化类型更改为数组，或者将实现集合接口的类型(例如ICollection，IList)更改为List，例如可以从中进行反序列化的List JSON array.JsonObjectAttribute也可以添加到类型中，以强制其从JSON数组反序列化.}

{Newtonsoft.Json.JsonSerializationException: Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'iChargeClassTest.CharchingPointClass' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly. To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from JSON array.JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON array.}

有人可以帮我吗?

非常感谢您的帮助:)

推荐答案

您必须使用该行进行反序列化.

You have to use the line for Deserializing.

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

班级将是

  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; }
 }
