## 实现 ##

参照第一篇文章引进ProBuf，然后下载ICSharpCode.SharpZipLib.dll，再参照第三篇文章

引用ICSharpCode。

在窗体上拖拽Button按钮，然后双击进点击事件。

private void button8_Click(object sender, EventArgs e)
            {
                DateTime begin = DateTime.Now;
                Console.WriteLine("ProtoBuf压缩开始" + begin.ToString("yyyy-MM-dd HH:mm:ss"));
                //初始化数据--创建10000个对象list
                for (int i = 0; i < 10000; i++)
                {
                    requestList.Add(new Request() {id=i,password="密码"+i});
                }
                try
                {
                    //创建内存流对象
                    MemoryStream ms = new MemoryStream();
                    //序列化对象
                    ProtoBuf.Serializer.Serialize<List<Request>>(ms, this.requestList);
                    //把内存流对象写入字节数组
                    byte[] buffer = ms.ToArray();
                    //关闭内存流对象    
                    ms.Close();
                    //释放资源                        
                    ms.Dispose();                                                            
                    //创建文件
                    FileStream fs = File.Create(@"E:\testdata1\Record4.zip");
                    //创建zip输出流
                    ZipOutputStream zipOutputStream = new ZipOutputStream(fs, buffer.Length);
                    //ZipEntry用于表示Zip文件条目 --将会在压缩文件中创建Record4.data文件
                    ZipEntry entry = new ZipEntry("Record4.data");
                    //将其放进压缩文件中
                    zipOutputStream.PutNextEntry(entry);
                    //将字节数组写入文件
                    zipOutputStream.Write(buffer, 0, buffer.Length);
                    zipOutputStream.Finish();
                    zipOutputStream.Close();
                    zipOutputStream.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("ProBuf压缩结束" + end.ToString("yyyy-MM-dd HH:mm:ss"));
                Console.WriteLine("共花费 " + ts.TotalSeconds);
            }
