.NET的XmlSerializer在被覆盖的特性 [英] .net XmlSerializer on overriden properties

问题描述

我有一个抽象属性的基类：

I have a base class with an abstract property:

public abstract int ID {get;set;}

现在，我有一个子类，这是XmlSerialized。所以，它具有：

now, I have a subclass, which is XmlSerialized. So, it has:

[XmlElement("something")]
public override int ID {
get { //... }
set { //... }
}

我无法移动的XmlElement属性基类，因为每个子类中都会有一个不同的XML的ElementName。

I cannot move the XmlElement attribute to baseclass, since every subclass will have a different xml elementname.

现在，当我反序列化这个类，我得到了以下错误：

Now, when I deserialize this class I get the following error:

会员Subclass.ID隐藏继承   成员BaseClass.ID'，但   不同的自定义属性。

Member 'Subclass.ID' hides inherited member 'BaseClass.ID', but has different custom attributes.

我该怎么办？

推荐答案

序列化和派生类型的反序列化工作时，覆盖的属性有 [的XmlElement] 和 [XmlAttribute] 属性，通过添加一个 [XmlIgnore] 属性。

Serialization and deserialization of derived types works when the overridden properties have [XmlElement] and [XmlAttribute] attributes, by adding an [XmlIgnore] attribute.

基类可以由抽象，使得它永远被实例化，因此，串行化或并行化。

The base class can be made abstract so that it can never be instantiated and therefore serialized or deserialized.

[Serializable]
public abstract class Base
{
    [XmlIgnore]
    public abstract Int32 ID { get; set; }
}
