反序列化JSON偏 [英] Deserialize partial JSON

问题描述

我有反序列化的JSON字符串对象问题

这是一个简单的JSON我从一个web服务获得：

  {
GetDataResult：
{
 \id\：1234，
 \cityname\：\新York\，
 \temperature\：300，
}，
} 
  

和我有一个类CityData看起来像这样

  [JSONObject的（GetDataResult）] 
公共类CityData 
 {
 [JsonProperty（ID）] 
公众诠释标识{搞定;组; } 
 
 [JsonProperty（城市名）] 
公共字符串CITYNAME {搞定;组; } 
 
 [JsonProperty（温度）] 
公众诠释温度{搞定;组; } 
} 
  

我尝试用方法DeserializeObject <的呼叫反序列化JSON / p>

  VAR cityData = JsonConvert.DeserializeObject< cityData>（响应）; 
  

但根元素似乎使问题...

难道你们知道我怎么能解决这个问题，让我得到一个CityData对象已填充？

解决方案

JSON响应包含中本身就含有表示数据结果的JSON字符串的对象。

您需要反序列化两次，一次为响应和多一个对于该数据的结果。

  VAR响应= JsonConvert.DeserializeObject< JObject>（responseStr）; 
 VAR dataResult =（字符串）响应[GetDataResult]; 
 VAR cityData = JsonConvert.DeserializeObject< CityData>（dataResult）; 
  

I have a problem with deserializing a Json-string to an object.

This is a sample json i receive from a webservice:

{
    "GetDataResult":
                 "{
                     \"id\":1234,
                     \"cityname\":\"New York\",
                     \"temperature\":300,
                  }"
}

And I have a class CityData that looks like this

[JsonObject("GetDataResult")]
public class CityData
{
    [JsonProperty("id")]
    public int Id { get; set; }

    [JsonProperty("cityname")]
    public string CityName { get; set; }

    [JsonProperty("temperature")]
    public int Temperature { get; set; }
}

I try to deserialize the json with a call of the method DeserializeObject

var cityData = JsonConvert.DeserializeObject<CityData>(response);

but the root element seems to make problems...

Do you guys know how I can fix it, so that I receive a CityData-object with the data filled in?

解决方案

The json response contains an object that within itself contains a json string representing the data result.

You need to deserialize twice, once for the response and one more for the data result.

var response = JsonConvert.DeserializeObject<JObject>(responseStr);
var dataResult = (string)response["GetDataResult"];
var cityData = JsonConvert.DeserializeObject<CityData>(dataResult);
