C#序列化和反序列化之一-二进制序列化

      本系列文章主要介绍C#应用程序开发中常用的序列化和反序列化技术（不包含Web服务中的序列化，详见C#序列化与反序列化），包括以下两种方式：

1. 二进制序列化
2. XML序列化和反序列化

           首先介绍二进制序列化，二进制序列化是使用BinaryFormatter 类的实例方法 Serialize(Stream, Object) 和 Deserialize(Stream) 方法来实现的，以下是本人写的一个支持泛型的BinarySerialize类：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.IO;using System.Runtime.Serialization.Formatters.Binary;namespace JZC.Runtime.Serialization{    /// <summary>    /// BinarySerialize class,provider basic Serialize and Deserialize method.    /// </summary>    public class BinarySerialize<T>    {        private string _strFilePath = string.Empty;        public void Serialize(T obj, string strFilePath)        {            _strFilePath = strFilePath;            FileInfo fi = new FileInfo(_strFilePath);            if (fi.Exists)                throw new ArgumentException("File specified is exist already!");            using (FileStream fs = new FileStream(_strFilePath, FileMode.Create))            {                BinaryFormatter formatter = new BinaryFormatter();                formatter.Serialize(fs, obj);            }        }        /// <summary>        /// Deserialize an instance of T.        /// </summary>        /// <typeparam name="T">Any type.</typeparam>        /// <returns>The result of deserialized.</returns>        public T DeSerialize(string filePath)        {            FileInfo fi = new FileInfo(filePath);            if (!fi.Exists)                throw new ArgumentException("File specified is not exist!");            T t;            using (FileStream fs = new FileStream(filePath, FileMode.Open))            {                BinaryFormatter formatter = new BinaryFormatter();                try                {                    t = (T)formatter.Deserialize(fs);                }                catch (Exception ex)                {                    throw ex;                }            }            return t;        }    }}

假如我们有一个名字为Book的类：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Collections;namespace TestSerialize{    [Serializable]    public class Book    {        public Book()        {            AllBookReaders = new ArrayList();        }        public string BookName { get; set; }        [NonSerialized()]        public string strBookPwd;        private string _bookID;        public string BookID        {            get { return _bookID; }            set            {                if (_bookID != value)                {                    _bookID = value;                }            }        }        public ArrayList AllBookReaders { get; set; }        private string _bookPrice;        public string BookPrice        {            get { return _bookPrice; }            set            {                if (_bookPrice != value)                {                    _bookPrice = value;                }            }        }    }}

那么我们就可以用以下方法来序列化Book类，这里我使用了IList<Book>的对象来做测试。

using System;using System.Collections.Generic;using System.Linq;using System.Text;using JZC.Runtime.Serialization;namespace TestSerialize{    class Program    {        static void Main(string[] args)        {            IList<Book> books = new List<Book>();                       Book book = new Book();            book.BookID = "jzcBook1";            book.AllBookReaders.Add("jiangzhanchang");            book.AllBookReaders.Add("dingyinqian");            book.BookName = "C#Programming";            book.strBookPwd = "8907";            book.BookPrice = "69.00";            books.Add(book);            book = new Book();            book.BookID = "JzcBook2";            book.AllBookReaders.Add("huanghaiyan");            book.AllBookReaders.Add("sunyouyi");            book.BookName = "WPF Primer";            book.strBookPwd = "0908";            book.BookPrice = "78.00";            books.Add(book);            BinarySerialize<IList<Book>> serialize = new BinarySerialize<IList<Book>>();            string filePath=@"D:\bookSerialize.data";            serialize.Serialize(books, filePath);        }    }}

这样，就会产生一个文件名为  D:\bookSerialize.data 的文件，我们可以在任何一个AppDomain中将这个文件反序列化成一个IList<Book>的对象，方法如下：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using JZC.Runtime.Serialization;using TestSerialize;namespace TestDeserialize{   class Program    {        static void Main(string[] args)        {            BinarySerialize<IList<Book>> serialize = new BinarySerialize<IList<Book>>();            IList<Book> books = serialize.DeSerialize(@"D:\bookSerialize.data");        }    }}

我们可以加断点，看到反序列化的结果。
