C#读取XML资料

C#读取XML文件
我想读取如下的XML文件到内存，文件的树状结构是不定的，邮箱和关键字的对应关系可能是一对一，一对多，多对一，多对多。
打算用ArryList11来保存group1节点下的Email字段
  用ArryList12来保存group1节点下的KeyWord字段
依此类推。
看了MSDN的帮助示例，还是不太会操作XML文件，大虾们能否给个思路？
谢谢了。

C# code

<?xml version="1.0" encoding="utf-8"?><Configuration>    <group>    <Email>xxx@163.com</Email>    <KeyWord>java</KeyWord>  </group>  <group>    <Email>xxx@163.com</Email>    <KeyWord>sql</KeyWord>    <KeyWord>数据库</KeyWord>    <KeyWord>存储过程</KeyWord>    <KeyWord>游标</KeyWord>  </group>  <group>    <Email>xxx@163.com</Email>    <Email>xxx@163.com</Email>    <Email>xxx@163.com</Email>    <Email>xxx@163.com</Email>    <KeyWord>求助</KeyWord>  </group>  <group>    <Email>xxx@163.com</Email>    <Email>xxx@163.com</Email>    <Email>xxx@163.com</Email>    <Email>xxx@163.com</Email>    <KeyWord>c#</KeyWord>    <KeyWord>C++</KeyWord>    <KeyWord>c</KeyWord>  </group></Configuration>

C# code

 private void ReadXml()    {        ArrayList ArryList11 = new ArrayList();        ArrayList ArryList12 = new ArrayList();        //假设你的xml文件名为demo.xml确保路径正确        string xmlPath = Server.MapPath("demo.xml");        XmlDocument xmlDoc = new XmlDocument();        xmlDoc.Load(xmlPath);        XmlNodeList xnl = xmlDoc.SelectSingleNode("Configuration").ChildNodes;        foreach (XmlNode node in xnl)        {            foreach (XmlNode emailnode in node.SelectNodes("Email"))            {                ArryList11.Add(emailnode.InnerText);            }            foreach (XmlNode keywordnode in node.SelectNodes("KeyWord"))            {                ArryList12.Add(keywordnode.InnerText);            }        }    }

还是使用xml 凡序列化为实体 class 的方式比较易于维护和使用。
构造2个类代码很简单
C# code
public class Configuration    {            Collection<Group> groups = new Collection<Group>();        [XmlElement(ElementName = "group")]        public Collection<Group> Groups        {            get { return groups; }            set { groups = value; }        }    }        public class Group    {        Collection<string> email = new Collection<string>();        [XmlElement(ElementName = "Email")]        public Collection<string> Email        {            get { return email; }            set { email = value; }        }                Collection<string> keyWord = new Collection<string>();        [XmlElement(ElementName = "KeyWord")]        public Collection<string> KeyWord        {            get { return keyWord; }            set { keyWord = value; }        }            }
