通过XmlSerializer 我们可以十分简单的将Model与XML进行转换

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 { /// <summary> /// 节点名是EleTeacher /// </summary> [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<Student> sds { set; get; } } [Serializable] public class Student { [XmlAttribute(AttributeName = "id")] public string ID { set; get; } [XmlText] public string Name { set; get; } } }
