無法將字符串轉換爲json

-2

我從withings獲取度量值，並希望在圖中顯示它們，但無法將其轉換爲json。我也嘗試使用JsonConvert.SerializeObject(myString)和Newtonsoft.dll簡單無法將字符串轉換爲json

System.Web.Script.Serialization.JavaScriptSerializer sr = new System.Web.Script.Serialization.JavaScriptSerializer(); 
sr.Serialize(myString);

但不轉換。

我的腰帶測量字符串如下。

    "body": {

會發生什麼？你有錯誤信息嗎？您是否嘗試過JSON的更小/子集？ – n8wrl

不，我沒有得到錯誤，但輸入相同的輸出 –

我編輯了你的標題。請參閱：「[應該在其標題中包含」標籤「]（http://meta.stackexchange.com/questions/19190/）」，其中的共識是「不，他們不應該」。 –

看來，要反序列化您的JSON字符串，不序列：

var obj = JsonConvert.DeserializeObject<Withings.RootObject>(json);

public class Withings 
{ 
    public class Measure 
    { 
     public int value { get; set; } 
     public int type { get; set; } 
     public int unit { get; set; } 
    } 

    public class Measuregrp 
    { 
     public int grpid { get; set; } 
     public int attrib { get; set; } 
     public int date { get; set; } 
     public int category { get; set; } 
     public List<Measure> measures { get; set; } 
    } 

    public class Body 
    { 
     public int updatetime { get; set; } 
     public List<Measuregrp> measuregrps { get; set; } 
    } 

    public class RootObject 
    { 
     public int status { get; set; } 
     public Body body { get; set; } 
    } 
}

JsonConvert.SerializeObject(myString)需要一個對象返回一個字符串。如果要將字符串轉換爲要使用的對象Deserialize<T>(sting json)。鑑於您的示例中的參數名稱是myString我會假設您使用的方法錯誤。

要反序列化，您需要一個等效類型，如;

public class myObject 
    { 
     public int status { get; set; } 
     public Body body { get; set; } 
    } 
    public class Body 
    { 
      //other parameters ect 
    }

你的對象模型需要通過準確的Deserialize<T> JSON匹配才能正常運行。
