C#.NET对象深拷贝

//深拷贝 
        public static object Clone(object obj)
        {
            //创建内存流 
            MemoryStream ms = new MemoryStream();
            //以二进制格式进行序列化 
            BinaryFormatter bf = new BinaryFormatter();
            bf.Serialize(ms, obj);
            //反序列化当前实例到一个object 
            ms.Seek(0, 0);
            object res = bf.Deserialize(ms);
            //关闭内存流 
            ms.Close();
            return res;
        }
