.net XmlSerializer 覆盖属性

发布于 2024-10-15 21:31:31 字数 421 浏览 1 评论 0原文

我有一个带有抽象属性的基类：

public abstract int ID {get;set;}

现在，我有一个子类，它是 XmlSerialized。因此，它具有：

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

我无法将 XmlElement 属性移至基类，因为每个子类都有不同的 xml 元素名称。

现在，当我反序列化此类时，出现以下错误：

成员“Subclass.ID”隐藏继承的成员“BaseClass.ID”，但有不同的自定义属性。

我能做些什么？

原文

I have a base class with an abstract property:

public abstract int ID {get;set;}

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

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

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

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

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

What can I do?

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起作用。

基类可以被抽象化，这样它就永远不会被实例化，从而无法序列化或反序列化。

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

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

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; }
}

使基类属性受保护且非抽象，然后为每个派生类提供一个根据基类属性实现的适当命名的属性：

// Base class
protected int InternalID {get; set;}

// Derived class
[XmlElement]
public int SomethingID
{
  get {return InternalID;}
  set {InternalID = value;}
}

Make the base class property protected and non-abstract, then give each derived class an appropriately named property implemented in terms of the base class property:

// Base class
protected int InternalID {get; set;}

// Derived class
[XmlElement]
public int SomethingID
{
  get {return InternalID;}
  set {InternalID = value;}
}
