继承自List< T>的对象 [英] Serializing object that inherits from List<T>

问题描述

当我尝试序列化此集合时，name属性未序列化.

When I try to serialize this collection, the name property is not serialized.

public class BCollection<T> : List<T> where T : B_Button
{       
   public string Name { get; set; }
}


BCollection<BB_Button> bc = new BCollection<B_Button>();

bc.Name = "Name";// Not Serialized!

bc.Add(new BB_Button { ID = "id1", Text = "sometext" });

JavaScriptSerializer serializer = new JavaScriptSerializer();
string json = serializer.Serialize(bc);

仅当我创建一个新类(没有 List< t> 继承)，并在其中定义字符串 Name 属性和 List< B_Button>时，bc = new List< B_Button>(); 属性，我得到了正确的结果.

Only if I create a new class (without List<t> inheritance), and define there string Name property and List<B_Button> bc = new List<B_Button>(); property I get the right result.

推荐答案

在许多序列化程序(实际上是数据绑定)中，对象是 实体或(不包括)列表；通常不支持在列表上具有 属性.我将重构为封装列表:

In many serializers (and data-binding, in fact), an object is either an entity or (exclusive) a list; having properties on a list is not commonly supported. I would refactor to encapsulate the list:

public class Foo<T> {
    public string Name {get;set;}
    private readonly List<T> items = new List<T>();
    public List<T> Items { get { return items; } }
}

也；您打算如何用JSON表示它?IIRC JSON数组语法不允许任何额外的属性两者.

Also; how would you plan on representing that in JSON? IIRC the JSON array syntax doesn't allow for extra properties either.
