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; }
    }
}
