using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.IO;

using System.Xml;

using System.Xml.Serialization;



namespace ConsoleApplication2

{

    public class SimpleSerializer

    {

        /// <summary>



        /// 序列化对象

                return xz.Deserialize(sr);

            }

        }

    }

}


定义一个用于测试的实体类: UserInfo


using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Xml.Serialization;



namespace ConsoleApplication2

{

    [Serializable]

    public class UserInfo

    {

        private int m_UserId;



        [XmlElement("userId")]

        public int UserId

        {

            get { return m_UserId; }

            set { m_UserId = value; }

        }

        private string m_UserName;



        [XmlElement("userName")]

        public string UserName

        {

            get { return m_UserName; }

            set { m_UserName = value; }

        }

    }

}


编写测试子程序:



using System;

using System.Collections.Generic;



namespace ConsoleApplication2

{

    class Program

    {

        static void Main(string[] args)

        {

            Program.TestOne();

            Console.WriteLine(string.Empty);



            Program.TestTwo();

            Console.WriteLine(string.Empty);



            Program.TestThree();

            Console.WriteLine(string.Empty);



            Program.TestFour();

        }

        public static void TestOne()

        {

            UserInfo info = new UserInfo() { UserId = 1, UserName = "Guozhijian" };

            Console.WriteLine(SimpleSerializer.Serialize<UserInfo>(info));

        }

        public static void TestTwo()

        {

            List<UserInfo> list = new List<UserInfo>();

            list.Add(new UserInfo() { UserId = 1, UserName = "Guozhijian" });

            list.Add(new UserInfo() { UserId = 2, UserName = "Zhenglanzhen" });

            Console.WriteLine(SimpleSerializer.Serialize<List<UserInfo>>(list));

        }

        public static void TestThree()

        {

            string s = SimpleSerializer.Serialize<UserInfo>(new UserInfo() { UserId = 1, UserName = "Guozhijian" });

            UserInfo info = SimpleSerializer.Deserialize(typeof(UserInfo), s) as UserInfo;

            Console.WriteLine(info.UserId.ToString() + ", " + info.UserName);

        }

        public static void TestFour()

        {

            List<UserInfo> list = new List<UserInfo>();

            list.Add(new UserInfo() { UserId = 1, UserName = "Guozhijian" });

            list.Add(new UserInfo() { UserId = 2, UserName = "Zhenglanzhen" });

            string s = SimpleSerializer.Serialize<List<UserInfo>>(list);

            List<UserInfo> newList = SimpleSerializer.Deserialize(typeof(List<UserInfo>), s) as List<UserInfo>;

            foreach (var info in newList)

            {

                Console.WriteLine(info.UserId.ToString() + ", " + info.UserName);

            }

        }

    }

}


输出结果为:

C:\WINDOWS\system32\cmd.exe
