使用xml串行化就可以将类的实例转换为XML，反之亦然。开发人员经常需要进行XML穿行化。
      程序清单中展示了一个串行化的实例。第一步是创建 Person  类的实例，并用进行初始化。然后利用XmlSerializer将Person  类的这个实例串行化。 using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

/**//// <summary>
/// Person 的摘要说明
/// </summary>
public class Person
{
    public Person()
    {
        //
        // TODO: 在此处添加构造函数逻辑
        //
    }

    public string Name
    {
        set
        {
            _name = value;
        }
        get
        {
            return _name;
        }
    }   PRivate string _name;

    public int Age
    {
        set
        {
            _age = value;
        }
        get
        {
            return _age;
        }
    }   private int _age;
}

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Xml.Serialization" %>

<script runat="server">
   
    protected void Page_Load(object sender, EventArgs e)
    {
        Person person = new Person();
        person.Name = "☆聊ゾ聊☆";
        person.Age = 23;
        //Response.Clear();
        //Response.ContentType = "text/xml";
        XmlSerializer serializer = new XmlSerializer(person.GetType());
        serializer.Serialize(Response.OutputStream, person);
    }
</script>
运行后得到的结果： <?xml version="1.0"?>
<Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Name>☆聊ゾ聊☆</Name>
  <Age>23</Age>
</Person>
自定义串行化。假设需要把某个类的一个共有属性转换为　XML　属性，那么上面的做法就无法满足要求了。为了达到这一目的，我们可以实现自定义的XML串行化。程序清单如下： using System;
using System.Xml.Serialization;

[XmlRoot("员工")]
public class Employee
{
    public Employee()
    {
    }

    [XmlAttribute("姓名")]
    public string Name
    {
        set
        {
            _name = value;
        }
        get
        {
            return _name;
        }
    }   private string _name;

    [XmlAttribute("年龄")]
    public int Age
    {
        set
        {
            _age = value;
        }
        get
        {
            return _age;
        }
    }   private int _age;

    [XmlElement("备注")]
    public string Remarks
    {
        set
        {
            _remarks = value;
        }
        get
        {
            return _remarks;
        }
    }   private string _remarks;
}

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Xml.Serialization" %>

<script runat="server">
   
    protected void Page_Load(object sender, EventArgs e)
    {
        Employee employee = new Employee();
        employee.Name = "☆聊ゾ聊☆";
        employee.Age = 23;
        employee.Remarks = "☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆";
        //Response.Clear();
        //Response.ContentType = "text/xml";
        XmlSerializer serializer = new XmlSerializer(employee.GetType());
        serializer.Serialize(Response.OutputStream, employee);
    }
</script>

运行结果： <?xml version="1.0"?>
<员工 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" 姓名="☆聊ゾ聊☆" 年龄="23">
  <备注>☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆ ☆聊ゾ聊☆</备注>
</员工>
