c# - XML 序列化和继承

Question

class A : IXmlSerializable
{     ...
}

class B : A
{
   public string X;
}

当我序列化 B 类型的对象时，只有 A 被序列化。如何以最小的努力包含 X？

Answer 1

您正在实现 IXmlSerialized 的事实使其变得有点困难......

您可以做的是将 WriteXml 和 ReadXml 设为虚拟，并在派生类中重写它们:

public class A : IXmlSerializable
{
    public virtual void WriteXml (XmlWriter writer)
    {
        // Serialize A members
    }

    public virtual void ReadXml (XmlReader reader)
    {
        // Deserialize A members
    }

    public XmlSchema GetSchema()
    {
        return(null);
    }


}


public class B : A
{
    public override void WriteXml (XmlWriter writer)
    {
        base.WriteXml(writer);

        // Serialize B members
    }

    public virtual void ReadXml (XmlReader reader)
    {
        base.ReadXml(reader);

        // Deserialize B members
    }
}
