.net XmlSerializer覆盖的属性 [英] .net XmlSerializer on overridden properties

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.因此，它具有:

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

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

我无法将XmlElement属性移至基类，因为每个子类将具有不同的xml元素名称.

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，会出现以下错误:

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

成员"Subclass.ID"隐藏继承 成员"BaseClass.ID"，但具有 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

当重写的属性具有[XmlElement]和[XmlAttribute]属性(通过添加[XmlIgnore]属性)时，派生类型的序列化和反序列化将起作用.

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

可以将基类抽象化，以使其永远无法实例化，因此不能序列化或反序列化.

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; }
}
