反序列化具有未知對象名稱的JSON

Question

我試圖從API反序列化JSON響應。 JSON看起來像這樣（MAC地址和位置被改變）：

{ 
"body" : [{ 
     "_id" : "da:87:54:26:53:97", 
     "place" : { 
      "location" : [-23.334961, 47.398349], 
      "altitude" : 30, 
      "timezone" : "Europe\/London" 
     }, 
     "mark" : 3, 
     "measures" : { 
      "f2:bf:a7:6f:e7:e8" : { 
       "res" : { 
        "1469997248" : [20.4, 66] 
       }, 
       "type" : ["temperature", "humidity"] 
      }, 
      "42:b7:48:59:7c:4b" : { 
       "res" : { 
        "1469997263" : [1016.7] 
       }, 
       "type" : ["pressure"] 
      } 
     }, 
     "modules" : ["f2:bf:a7:6f:e7:e8"] 
    } 
], 
"status" : "ok", 
"time_exec" : 0.034152030944824, 
"time_server" : 1469997417 
} 

問題是度量塊。由於該對象的名稱正在改變，我不知道如何正確地反序列化爲一個C＃對象。 I found a similiar problem on here with the solution to use a dictonary，但是，如果我嘗試這種方式，我只是得到空目錄。

這是我的反序列化方法：

APIResponse apiResponse = JsonConvert.DeserializeObject<APIResponse>(await content.ReadAsStringAsync()); 

這是APIResponse類：

public class APIResponse 
{ 
    public Body[] body { get; set; } 
    public string status { get; set; } 
    public float time_exec { get; set; } 
    public int time_server { get; set; } 
} 

public class Body 
{ 
    public string _id { get; set; } 
    public Place place { get; set; } 
    public int mark { get; set; } 
    public Measures measures { get; set; } 
    public string[] modules { get; set; } 
} 

public class Place 
{ 
    public float[] location { get; set; } 
    public float altitude { get; set; } 
    public string timezone { get; set; } 
} 

public class Measures 
{ 
    public Dictionary<string, SingleModule> singlemodules{ get; set; } 
} 

public class SingleModule 
{ 
    public Res res { get; set; } 
    public string[] type { get; set; } 
} 

public class Res 
{ 
    public MeasuredData measuredData { get; set; } 
} 
public class MeasuredData 
{ 
    public float[] values { get; set; } 
} 

任何方式妥善容易derserialize措施？

Answer 1

看起來你應該能夠擺脫你的Measures類。相反，把字典直入你的Body類：

public class Body 
{ 
    public string _id { get; set; } 
    public Place place { get; set; } 
    public int mark { get; set; } 
    public Dictionary<string, SingleModule> measures { get; set; } 
    public string[] modules { get; set; } 
} 

作爲一個獨立問題，我強烈推薦以下.NET命名約定的性能並且使用[JsonProperty("measures")]等來指示Json.NET如何翻譯你的屬性轉換成JSON。
