问题描述
我有一个带有抽象属性的基类:
I have a base class with an abstract property:
public abstract int ID {get;set;}
现在，我有一个子类，它是 XmlSerialized.所以，它有:
now, I have a subclass, which is XmlSerialized. So, it has:
[XmlElement("something")]
public override int ID {
get { //... }
set { //... }
}
我无法将 XmlElement 属性移动到基类，因为每个子类都有不同的 xml 元素名.
I cannot move the XmlElement attribute to baseclass, since every subclass will have a different xml elementname.
现在，当我反序列化此类时，出现以下错误:
Now, when I deserialize this class I get the following error:
成员 'Subclass.ID' 隐藏继承成员BaseClass.ID"，但有不同的自定义属性.
Member 'Subclass.ID' hides inherited member 'BaseClass.ID', but has different custom attributes.
我能做什么?
推荐答案
当被覆盖的属性有 [XmlElement] 和 [XmlAttribute] 时，派生类型的序列化和反序列化工作属性，通过添加 [XmlIgnore] 属性.
Serialization and deserialization of derived types works when the overridden properties have [XmlElement] and [XmlAttribute] attributes, by adding an [XmlIgnore] attribute.
基类可以被抽象化，这样它就不能被实例化，因此不能被序列化或反序列化.
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; }
}
