同时也可以通过设置Model的特性，灵活的控制序列化
using System.Xml.Serialization;using System;using System.Collections.Generic;namespace Model{ /// /// 节点名是EleTeacher /// [Serializable] [XmlType("EleTeacher")] public class Teacher { [XmlElement(ElementName = "user")] public string AuthorID { set; get; } [XmlIgnore] public string Content { set; get; } [XmlText] public string Value { set; get; } [XmlArray("students")] public List sds { set; get; } } [Serializable] public class Student { [XmlAttribute(AttributeName = "id")] public string ID { set; get; } [XmlText] public string Name { set; get; } }}
