爲什麼base class屬性在上一次被序列化？

Question

我有一個基類

public class ParentSystemInfo 
{ 
    private string _Version = "R8.1"; 

    public SystemInfo() 
    { 

     this.Version = _Version; 
    } 

    } 
    public string Version { 

     get { return _Version; } 
     set { _Version = value; } 
    }  
} 

我繼承它在另一個類

public class ChildSystemInfo : ParentSystemInfo 
{ 

    public ChildSystemInfo() :base() 
    { 

     this.MYInfo= new MYInfo(); 

    } 
    public string Name { get; set; } 
    public MYInfo MYInfo{ get; set; }  
} 

當我序列化這個類我沒有在啓動JSON的結束得到parent屬性。爲什麼會發生這種情況，我如何防止它發生。

您可以使用Json屬性屬性來控制屬性被排序的順序。在這裏看到的文檔：http://www.newtonsoft.com/json/help/html/JsonPropertyOrder.htm

所以你會：

public class ParentSystemInfo 
{ 
    private string _Version = "R8.1"; 

    public SystemInfo() 
    { 
     this.Version = _Version; 
    } 

    // Setting the JsonProperty to be -1 will ensure it appears before 
    // all properties for which this attribute was not set. 
    [JsonProperty(Order = -1)] 
    public string Version { 
     get { return _Version; } 
     set { _Version = value; } 
    }  
}
