使用.NET的XmlSerializer时忽略派生类的属性

using System;
using System.Xml.Serialization;

public class BaseClass
{
    public string BaseProperty { get; set; }
}

public class DerivedClass : BaseClass
{
    [XmlIgnore]
    public string DerivedProperty { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        DerivedClass derivedObj = new DerivedClass()
        {
            BaseProperty = "BaseValue",
            DerivedProperty = "DerivedValue"
        };

        XmlSerializer serializer = new XmlSerializer(typeof(DerivedClass));
        using (var writer = new StringWriter())
        {
            serializer.Serialize(writer, derivedObj);
            Console.WriteLine(writer.ToString());
        }
    }
}

<?xml version="1.0" encoding="utf-16"?>
<DerivedClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <BaseProperty>BaseValue</BaseProperty>
</DerivedClass>
