工具类
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; }
}
}
