对象,对象集合的简单Xml序列化与反序列化

本文描述如何使用CLR中的StringWriter,XmlSerializer将对象, 对象集合序列化为Xml格式的字符串, 同时描述如何进行反序列化.

C#版本: C# 3.0
开发环境: VS 2008

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        /// </summary>        /// <typeparam name="T">对象类型</typeparam>        /// <param name="t">对象</param>        /// <returns></returns>        public static string Serialize<T>(T t)        {            using (StringWriter sw = new StringWriter())            {                XmlSerializer xz = new XmlSerializer(t.GetType());                xz.Serialize(sw, t);                return sw.ToString();            }        }        /// <summary>        /// 反序列化为对象        /// </summary>        /// <param name="type">对象类型</param>        /// <param name="s">对象序列化后的Xml字符串</param>        /// <returns></returns>        public static object Deserialize(Type type, string s)        {            using (StringReader sr = new StringReader(s))            {                XmlSerializer xz = new XmlSerializer(type);                return xz.Deserialize(sr);            }        }    }}

定义一个用于测试的实体类: UserInfo

编写测试子程序:
