首先，封装一个XML序列化和反序列化的函数。

using System.Xml.Serialization; using System.IO;

 

public class XmlSerialize { /// <summary> /// 反序列化XML为类实例 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="xmlObj"></param> /// <returns></returns> public static T DeserializeXML<T>(string xmlObj) { XmlSerializer serializer = new XmlSerializer(typeof(T)); using (StringReader reader = new StringReader(xmlObj)) { return (T)serializer.Deserialize(reader); } } /// <summary> /// 序列化类实例为XML /// </summary> /// <typeparam name="T"></typeparam> /// <param name="obj"></param> /// <returns></returns> public static string SerializeXML<T>(T obj) { using (StringWriter writer = new StringWriter()) { new XmlSerializer(obj.GetType()).Serialize((TextWriter)writer, obj); return writer.ToString(); } } }

再建一个实体类，添加序列化标记

[Serializable] public class UserInfo { public string Name; public string sex; }

OK，我们先来序列化一下

static void Main(string[] args) { UserInfo user = new UserInfo(); user.Name = "bdstjk"; user.sex = "男"; String strXml = XmlSerialize.SerializeXML<UserInfo>(user); Console.WriteLine(strXml); }

序列化结果：

<?xml version="1.0" encoding="utf-16"?> <UserInfo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Name>bdstjk</Name> <sex>男</sex> </UserInfo>

反序列化我们就用这个序列化后的XML后吧

static void Main(string[] args) { string strXml = "<?xml version=\"1.0\" encoding=\"utf-16\"?><UserInfo xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\"><Name>bdstjk</Name><sex>男</sex></UserInfo>"; UserInfo user = XmlSerialize.DeserializeXML<UserInfo>(strXml); Console.WriteLine(user.Name); }

好了。。最简单的XML序列化，反序列化已经完成。。

复杂一些的XML操作，请看：
