C＃中的循環Json屬性

Question

我收到以下JSON字符串。它是產品規格的一部分。數據表示標題（「常規」）和Key值對中的項目。

我不想硬編碼任何性質，例如一般情況下，顯示功能和應該能夠

1. 檢索頁眉上的密鑰值對
2. 迭代。

到目前爲止，我有以下代碼

foreach (var SpecList in objAPIProduct.categorySpecificInfoV1.specificationList) 
{  
    foreach(dynamic SpecItem in SpecList.General) 
    { 
     Console.WriteLine(SpecItem.key); 
     Console.WriteLine(SpecItem.value[0]); 
    }  
} 

我想擺脫，我在內部foreach循環已經硬編碼，使環通用於所有屬性中的「常規」屬性的。 這裏是JSON的，我有

{ 
    "General": [{ 
     "key": "Sales Package", 
     "value": ["Laptop, Power Adapter, Warranty Document"] 
    }, 
    { 
     "key": "Model Number",

在嘗試了很多選項後，我發現在使用Json.Net或JavascriptSerialiser時無法獲得屬性的「名稱」。

最後，我用這個線索的幫助下 -

Deserialize JSON into C# dynamic object?

其中的人已使用System.Web.Helpers建議和它完美的作品在我的情況。

這裏是我的最終代碼： dynamic objAPIProduct = Json.Decode（json）;

List<ProductSpecification> objProductSpecificationList = new List<ProductSpecification>(); 
      ProductSpecification objProductSpecification; 

      foreach (var SpecListCategoryList in objAPIProduct.categorySpecificInfoV1.specificationList) 
      { 
       foreach (var SpecCategory in SpecListCategoryList) 
       { 

        DynamicJsonArray objListitems = SpecCategory.Value; 

        for (int i = 0; i < objListitems.Length; i++) 
        { 
        objProductSpecification = new ProductSpecification(); 
        objProductSpecification.SpecificationHead = SpecCategory.Key; 
        objProductSpecification.SpecificationKey = objListitems[i].key; 
        objProductSpecification.SpecificationValue = objListitems[i].value[0]; 
        objProductSpecificationList.Add(objProductSpecification); 
        } 
       } 

      } 

Answer 2

在現場json2csharp.com你可以爲你的JSON生成類。

public class General 
{ 
    public string key { get; set; } 
    public List<string> value { get; set; } 
} 

public class RootObject 
{ 
    public List<General> General { get; set; } 
} 

和反序列化JSON它使用JSON.NET到：

RootObject ro = JsonConvert.DeserializeObject<RootObject>(json); 

和：

foreach(General g in ro.General) 
{ 
    string k = g.key; 
} 

Answer 3

重寫你的SpecList類這樣

public class SpecList : Dictionary<string, List<SpecItem>> 
{ 
} 

從此，你將能夠acc這是你的一般財產

foreach (var SpecList in objAPIProduct.categorySpecificInfoV1.specificationList) 
{ 
    foreach(var key in SpecList.Keys) 
    { 
     foreach(var SpecItem in SpecList[key]) 
     { 
      Console.WriteLine(SpecItem.key); 
      Console.WriteLine(SpecItem.value[0]); 
     }  
    } 
} 

希望它有幫助。
