## 实现 ##

在上面文章的基础上，将压缩好的文件进行解压缩并将其进行二进制反序列化。

Winform窗体上拖拽按钮，双击进入其点击事件。

private void button9_Click(object sender, EventArgs e)
            {
                DateTime begin = DateTime.Now;
                Console.WriteLine("解压缩并二进制反序列化开始" + begin.ToString("yyyy-MM-dd HH:mm:ss"));
                try
                {
                    int bufferSize = 40960;
                    //打开文件
                    FileStream fs = File.OpenRead(@"E:\testdata1\Record3.zip");
                    //设置文件流的位置
                    fs.Position = 0;
                    //通过ZIpInputStream得到zip文件的对象                                           
                    ZipInputStream zipInputStream = new ZipInputStream(fs, bufferSize);
                    //通过zip.getNextEntry（）来得到ZipEntry对象
                    zipInputStream.GetNextEntry();
                    //定义数据缓冲
                    byte[] buffer = new byte[bufferSize];
                    //定义读取位置                       
                    int offset = 0;
                    //定义内存流                                    
                    MemoryStream ms = new  MemoryStream();                     
                    while ((offset = zipInputStream.Read(buffer, 0, buffer.Length)) != 0)
                    {
                        //解压后的数据写入内存流
                        ms.Write(buffer, 0, offset);                                             
                    }
                    //设置内存流的位置
                    ms.Position = 0;
                    //反序列化
                    BinaryFormatter formatter = new BinaryFormatter();
                    this.personList = formatter.Deserialize(ms) as List<Person>;                     
                    ms.Close();
                    ms.Dispose();
                    //关闭流
                    fs.Close();
                    //释放对象                
                    fs.Dispose();                                                             
                }
                catch (Exception ex)
                {
                    Console.WriteLine(ex.Message);
                }
                DateTime end = DateTime.Now;
                TimeSpan ts = end - begin;
                Console.WriteLine("解压缩并使用二进制反序列化结束" + end.ToString("yyyy-MM-dd HH:mm:ss"));
                Console.WriteLine("共花费" + ts.TotalSeconds);
                foreach(Person p in personList)
                {
                    Console.WriteLine("Id:"+p.Id+"密码:"+p.Password);
                }
            }
