本文介绍了一个使用C#实现的XML序列化示例，包括如何将Person对象列表序列化到XML文件中，以及如何从XML文件中反序列化数据。演示了两种情况：一种是对Person类的List进行操作；另一种是对包含Person对象的ArrayList进行操作。

XML与Object序列化

    public partial class XmlSerializerDemo : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                //this.LoadData();
                this.MyArrayList();
            }
        }

        /// <summary>
        /// 加载数据
        /// </summary>
        private void LoadData()
        {
            List<Person> people = new List<Person>();
            people.Add(new Person("0001", "张三"));
            people.Add(new Person("0002", "李四"));
            XmlSerializer s = new XmlSerializer(typeof(List<Person>));
            TextWriter w = new StreamWriter(Server.MapPath("~/person.xml"));
            s.Serialize(w, people);
            w.Close();

            //XmlSerializer s = new XmlSerializer(typeof(Person));
            //TextWriter w = new StreamWriter(Server.MapPath("~/person1.xml"));
            //s.Serialize(w, p);
            //w.Close();

            TextReader r = new StreamReader(Server.MapPath("~/person.xml"));
            List<Person> listPerson = s.Deserialize(r) as List<Person>;
            r.Close();
            Response.Write(listPerson[1].Name);
        }

        /// <summary>

        public void MyArrayList()
        {
            ArrayList people = new ArrayList();
            people.Add(new Person("001", "王雪"));
            people.Add(new Person("002", "茼桐"));

            XmlSerializer s = new XmlSerializer(typeof(ArrayList), new Type[] { typeof(Person) });
            TextWriter w = new StreamWriter(Server.MapPath("~/p.xml"));
            s.Serialize(w, people);
            w.Close();

            TextReader r = new StreamReader(Server.MapPath("~/p.xml"));

            ArrayList array = s.Deserialize(r) as ArrayList;

            foreach (Person al in array)
            {
                Response.Write("序号为：" + al.Id + "&nbsp;&nbsp;&nbsp;&nbsp;");
                Response.Write("姓名为："+al.Name+"<br/>");
            }
        }
    }

    public class Person
    {
        public Person() { }


        public Person(string id, string name)
        {
            Id = id;
            Name = name;
        }

        public string Id { get; set; }

        public string Name { get; set; }
    }
