namespace IOStream
{

    public class Person
    {
        public Person() { }

        private int id;
        private string name;
        private string place;
        public int Id
        {
            get { return id; }
            set { id = value; }
        }
        public string Name
        {
            get { return name; }
            set { name = value; }
        }
        public string Place
        {
            get { return place; }
            set { place = value; }
        }

    }

    /*使用xml串行化将对象保存为xml数据*/
    class StringTest
    {
        public static void Main()
        {
            Person p1 = new Person();
            p1.Id = 1;
            p1.Name = "小明";
            p1.Place = "武汉";

            Person p2 = new Person();
            p2.Id = 2;
            p2.Name = "许愿";
            p2.Place = "南昌";
            Person p3 = new Person();
            p3.Id = 3;
            p3.Name = "有娴心";
            p3.Place = "成都";

            Person[] ps ={ p1, p2, p3 };

            XmlRootAttribute xRoot = new XmlRootAttribute();
            xRoot.ElementName = "people";
            xRoot.Namespace = "http://www.xx.com";
            xRoot.IsNullable = true;
            XmlSerializer xSerial = new XmlSerializer(typeof(Person[]), xRoot);
            string filename = @"c:\people.xml";
            TextWriter writer = new StreamWriter(filename);
            xSerial.Serialize(writer, ps);

            Console.ReadLine();
        }
    }


}

运行结果如下：


<?xml version="1.0" encoding="utf-8"?>
<people xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.xx.com">
  <Person>
    <Id>1</Id>
    <Name>小明</Name>
    <Place>武汉</Place>
  </Person>
  <Person>
    <Id>2</Id>
    <Name>许愿</Name>
    <Place>南昌</Place>
  </Person>
  <Person>
    <Id>3</Id>
    <Name>有娴心</Name>
    <Place>成都</Place>
  </Person>
</people>
