反序列化对象时出错 [英] Error in deserialising the objects

问题描述

我有一个JSON字符串.

I have a JSON string.

[  
 {  
  "target":"FDOL00001",
  "datapoints":[  
     {  
        "y":72.564,
        "x":1523858700
     }
  ]
 },
 {  
  "target":"FDOL00001",
  "datapoints":[  
     {  
        "y":86.366,
        "x":1523858700
     }
  ]
 },
 {  
  "target":"FDOL00001",
  "datapoints":[  
     {  
        "y":73.90195818815343,
        "x":1523858700
     }
  ]
 }
]

我正在尝试将其反序列化为一个集合.但是我遇到了一个错误.有人可以指导我采取正确的方法解决此问题吗?

I am trying to deserialise it to a collection. But I am getting an error. Can somebody direct me to the right way to fix this?

class datapoint
{
    [JsonProperty("x")]
    public int x { get; set; }
    [JsonProperty("y")]
    public decimal y { get; set; }
}
class jsonMapper
{
    [JsonProperty("target")]
    public string target { get; set; }
    [JsonProperty("datapoints")]
    public datapoint datapoints { get; set; }
}

我正在尝试使用以下代码进行转换.

I am trying to convert using the following code.

var json = JsonConvert.DeserializeObject<List<jsonMapper>>(objText);

我得到的错误是

无法将当前JSON数组(例如[1,2,3])反序列化为类型"ISSPortal2.datapoint"，因为该类型需要一个JSON对象(例如{\"name \":\"value \"}) \ r \ n要解决此错误，请将JSON更改为JSON对象(例如{\"name \":\"value \"})或将反序列化类型更改为数组或实现集合接口的类型(例如ICollection，IList)，例如可以从JSON数组反序列化的List.也可以将JsonArrayAttribute添加到该类型中，以强制其从JSON数组反序列化.\ r \ nPath'[0] .datapoints'，第1行，位置40.

Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'ISSPortal2.datapoint' because the type requires a JSON object (e.g. {\"name\":\"value\"}) to deserialize correctly.\r\nTo fix this error either change the JSON to a JSON object (e.g. {\"name\":\"value\"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.\r\nPath '[0].datapoints', line 1, position 40.

我已经检查了

I already checked this . But its not working. What's wrong in my code. Please help me to identify that. Thanks in advance :)

推荐答案

您正在尝试将数组datapoint[]反序列化为datapoint.

You're trying to deserialize array datapoint[] into datapoint.

更改

public datapoint datapoints { get; set; }

收件人

public datapoint[] datapoints { get; set; }

奖金::C#命名约定，建议您在公共财产中使用大写字母.

Bonus: C# Naming Conventions, suggest you to use Capital Letters in public properties.

class Datapoint
{
    [JsonProperty("x")]
    public int X { get; set; }
    [JsonProperty("y")]
    public decimal Y { get; set; }
}
class JsonMapper
{
    [JsonProperty("target")]
    public string Target { get; set; }
    [JsonProperty("datapoints")]
    public Datapoint Datapoints { get; set; }
}
