JSON。參考將反序列化爲空

Question

我正在使用Newtonsoft.json。我無法理解反序列化的結果。 Bulletin.PageList正在填寫好的。但是，引用PageList的元素的頁面始終爲空。在JsonSerializerSettings中，我指定了PreserveReferencesHandling.All，但它沒有幫助。你能幫助解決頁面null的問題嗎？謝謝

JSON structure: 

"Bulletins": [ 
     { 
      "$id": "46b5efa80fe644d7bd525e2c30f5df8a", 
      "$type": "Bulletin", 
      "JSONNETTYPE": "Bulletin", 
      "PagesList": [ 
       { 
        "id": "4ed13d727cd144d1acf1e0c9bc273245", 
        "JSONNETTYPE": "PageView", 
        "Number": 1, 
        "Id": "1a2b8ed4249948e194b396c46a5d1eeb", 
        "UiId": "4ed13d727cd144d1acf1e0c9bc273245" 
       } 
      ], 
      "AgendaQuestions": [ 
       { 
        "$id": "eceb6fe6c74a40d59f0673b76bd6dbb3", 
        "$type": "QSimple", 
        "Page": { 
         "$ref": "46b5efa80fe644d7bd525e2c30f5df8a#PagesList.0" 
        } 
       } 
      ] 
}] 

C＃結構：

public class Bulletin 
    {   
     public Bulletin() 
     {       
     } 

     public string Dbid { get; set; } 

     public List<PageView> PagesList; 

     public List<Question> AgendaQuestions; 
    } 

public abstract class Question 
    { 
     protected Question(int number, string customNumberLabel = null) 
     { 
      Number = number; 
      CustomNumberLabel = customNumberLabel; 
     } 

     public int Number { get; set; } 

     public string CustomNumberLabel { get; set; } 

     public PageView Page { get; set; }  
} 

public class PageView 
    { 
     public int Number { get; set; }  
     public string Id { get; set; }  
     public int BulletinNumber { get; set; }  
     public PageView() 
     {     
     }  
    } 
var settings = new JsonSerializerSettings 
{ PreserveReferencesHandling = PreserveReferencesHandling.All 

}

Answer 1

我用dojox.json.ref庫。如果我爲Page設置__id，對PagesList元素的引用將變爲直接的，而不是複雜的（如46b5efa80fe644d7bd525e2c30f5df8a＃PagesList.0），並且頁面被填充。
