不能派生屬性序列化爲JSON在網頁API

Question

我試圖讓這個類型的對象（通過Web API）：

public class Document 
{ 
    public int Id { get; set; } 
    public FileFolder Folder { get; set; } 
    public FileFolder FolderParent 
    { 
     get 
     { 
      return FileFolder.Folder; 
     } 
    } 
} 

我收到錯誤：

「錯誤獲取價值從'Domain.Document'上的'FolderParent'。「

Answer 1

我把一個快速的小例子放在一起，它很好的序列化。似乎錯誤必須來自我們現在沒有的FileFolder類的設計中的某個地方。

[TestClass] 
public class UnitTest8 
{ 
    [TestMethod] 
    public void TestJasonFileFolder() 
    { 
     var folder = new FileFolder(); 
     folder.Folder = new FileFolder { Name = "Parent" }; 
     folder.Name = "Something"; 

     var document = new Document { Folder = folder, Id = 1 }; 

     var test = JsonConvert.SerializeObject(document); 
     Assert.IsNotNull(test); 
    } 
} 

public class Document 
{ 
    public int Id { get; set; } 
    public FileFolder Folder { get; set; } 
    public FileFolder FolderParent 
    { 
     get 
     { 
      return this.Folder.Folder; 
     } 
    } 
} 

public class FileFolder 
{ 
    public string Name { get; set; } 
    public FileFolder Folder { get; set; } 
}
