C# XML序列化指定节点名称

[gooore]

您好，我在做XML序列化的时候有这么一段：

public List<XMLSystemChild> GetChildren
        {
            get { return m_oChildren; }
            set { m_oChildren = value; }
        }

List中的泛型XMLSystemChild是一个基类，被好多个派生类继承，这样我在输出XML序列化的时候遇到一个问题：

  <XMLSystemChild xsi:type="XMLChild" ID="XMP_3" TagName="test5">
    <Extent>
      <Max X="1" Y="1" Z="1" />
    </Extent>
    <PersistentID />
    <GenericAttributes Number="1" Set="test3">
      <GenericAttribute Name="test2" Format="string" Value="2" />
    </GenericAttributes>
    <XMLSystemChild xsi:type="XMLChildEx" ID="XMP_1" TagName="test">
      <Extent>
        <Max X="1" Y="1" Z="1" />
      </Extent>
      <PersistentID />
      <GenericAttributes Number="1" Set="test3">
        <GenericAttribute Name="test2" Format="string" Value="2" />
      </GenericAttributes>
    </XMLSystemChild>
  </XMLSystemChild>

节点中多 有个属性xsi:type="XMLChildEx" 说明派生类的类型。但是我不希望这样，希望能为每个派生类制定单独的节点名称。请问这个该如何做呢？

非常感谢您的解答！

谢谢您，我用XmlAttributeOverrides做好了

可以用XmlArrayItemAttribute：

using System;
using System.Collections.Generic;
using System.IO;
using System.Xml.Serialization;

class Program
{
    static void Main()
    {
        My my = new My()
        {
            Name = "Minion",
            Pets = new List<Pet>() { new Dog(), new Cat() }
        };

        XmlSerializer serializer = new XmlSerializer(typeof(My));
        using (StringWriter sw = new StringWriter())
        {
            serializer.Serialize(sw, my);
            string xml = sw.ToString();
            /*
            <My xmlns:xsd="...">
              <Name>Minion</Name>
              <Pets>
                <Dog />
                <Cat />
              </Pets>
            </My>
            */
        }
    }
}

public class My
{
    public string Name { get; set; }
    [XmlArrayItem("Dog", Type = typeof(Dog))]
    [XmlArrayItem("Cat", Type = typeof(Cat))]
    public List<Pet> Pets { get; set; }
}
public class Pet { }
public class Dog : Pet { }
public class Cat : Pet { }

可以用XmlArrayItemAttribute：

using System;
using System.Collections.Generic;
using System.IO;
using System.Xml.Serialization;

class Program
{
    static void Main()
    {
        My my = new My()
        {
            Name = "Minion",
            Pets = new List<Pet>() { new Dog(), new Cat() }
        };

        XmlSerializer serializer = new XmlSerializer(typeof(My));
        using (StringWriter sw = new StringWriter())
        {
            serializer.Serialize(sw, my);
            string xml = sw.ToString();
            /*
            <My xmlns:xsd="...">
              <Name>Minion</Name>
              <Pets>
                <Dog />
                <Cat />
              </Pets>
            </My>
            */
        }
    }
}

public class My
{
    public string Name { get; set; }
    [XmlArrayItem("Dog", Type = typeof(Dog))]
    [XmlArrayItem("Cat", Type = typeof(Cat))]
    public List<Pet> Pets { get; set; }
}
public class Pet { }
public class Dog : Pet { }
public class Cat : Pet { }

linq to xml，读取成IEnumerable<XElement> 集合之后处理。
