多态类型和IXmlSerializable

public class Person : IXmlSerializable
{
    public string Name { get; set; }
    public int Age { get; set; }

    public XmlSchema GetSchema()
    {
        return null;
    }

    public void ReadXml(XmlReader reader)
    {
        reader.MoveToContent();
        Name = reader.GetAttribute("Name");
        Age = int.Parse(reader.GetAttribute("Age"));
    }

    public void WriteXml(XmlWriter writer)
    {
        writer.WriteAttributeString("Name", Name);
        writer.WriteAttributeString("Age", Age.ToString());
    }
}

// 序列化
var person = new Person { Name = "John", Age = 30 };
var serializer = new XmlSerializer(typeof(Person));
using (var writer = new StringWriter())
{
    serializer.Serialize(writer, person);
    Console.WriteLine(writer.ToString());
}

// 反序列化
using (var reader = new StringReader<Person Name='John' Age='30' />"))
{
    var deserializedPerson = (Person)serializer.Deserialize(reader);
    Console.WriteLine(deserializedPerson.Name);
    Console.WriteLine(deserializedPerson.Age);
}
