C＃继承泛型集合和系列化 [英] c# inheriting generic collection and serialization

问题描述

的设置：

class Item
{
    private int _value;

    public Item()
    {
        _value = 0;
    }

    public int Value { get { return _value; } set { _value = value; } }
}

class ItemCollection : Collection<Item>
{
    private string _name;

    public ItemCollection()
    {
        _name = string.Empty;
    }

    public string Name { get {return _name;} set {_name = value;} }
}

现在，尝试使用以下code片段进行序列化：

Now, trying to serialize using the following code fragment:

ItemCollection items = new ItemCollection();

...

XmlSerializer serializer = new XmlSerializer(typeof(ItemCollection));
using (FileStream f = File.Create(fileName))
    serializer.Serialize(f, items);

当看着生成的XML我看到ItemCollection.Name值不存在！

Upon looking at the resulting XML I see that the ItemCollection.Name value is not there!

我想可能发生的是，串行认为作为一个简单的集合从而忽视了其他任何附加属性ItemCollection类型...

I think what may be happening is that the serializer sees the ItemCollection type as a simple Collection thus ignoring any other added properties...

有有遇到这样的问题的人，并找到了解决方法？

Is there anyone having encountered such a problem and found a solution?

问候，

推荐答案

此行​​为是通过设计。当从集合类派生的xml中会Seralizier仅序列化集合元素。要解决这个你应该创建一个封装的收集和名称的类，并有系列化。

This behavior is "By Design". When deriving from a collection class the Xml Seralizier will only serialize the collection elements. To work around this you should create a class that encapsulates the collection and the name and have that serialized.

class Wrapper
{
    private Collection<Item> _items;
    private string _name;

    public Collection<Item> Items { get {return _items; } set { _items = value; } }
    public string Name { get { return _name; } set { _name = value; } }
}
