.NET中制做对象的副本（三）通过序列化和反序列化为复杂对象制作副本

1、类的定义

 /// <summary>
    /// 学生信息
    /// </summary>
    [Serializable]
    public class Stu
    {
        /// <summary>
        /// 学生姓名
        /// </summary>
        public string Name { get; set; }

        /// <summary>
        /// 学生的老师
        /// </summary>
        public List<Teacher> Teachers { get; set; }
    }

    /// <summary>
    /// 老师信息
    /// </summary>
    [Serializable]
    public class Teacher
    {
        /// <summary>
        /// 老师姓名
        /// </summary>
        public string Name { get; set; }
        /// <summary>
        /// 学生列表
        /// </summary>
        public List<Stu> Stus { get; set; }
    }

2、实例化对象

这个学生类型比较复杂，和老师发生了循环引用。

            Stu stu = new Stu()
            {
                Name = "马良",
                Teachers = new List<Teacher>()
                {
                        new Teacher()
                        {
                                Name="老师1",
                                Stus=new List<Stu> (){}
                        }
                }
            };
            stu.Teachers[0].Stus.Add(stu);

3、对对象进行拷贝

     BinaryFormatter bfSerialize = new BinaryFormatter();
            MemoryStream ms = new MemoryStream();
            bfSerialize.Serialize(ms, stu);
            BinaryFormatter bfDeserialize = new BinaryFormatter();
            ms.Position = 0;
            Stu stu1 = (Stu)bfDeserialize.Deserialize(ms);
