## 场景 ##

ICSharpCode.SharpZipLib.dll 下载：

[https://download.csdn.net/download/badao\_liumang\_qizhi/11586902][https_download.csdn.net_download_badao_liumang_qizhi_11586902]

## 实现 ##

新建Winform窗体程序。

打开资源管理器-引用-右键-添加--浏览

选择刚才上面下载的ICSharpCode.SharpZipLib.dll，点击确定。

右击项目-添加-类

using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using System.Threading.Tasks;
    
    namespace ProtoBufTest
    {
        [Serializable]
        class Person
        {
    
            public Person(int id ,string password) {
                this.Id = id;
                this.Password = password;
            }
            private int id;
    
            public int Id
            {
                get { return id; }
                set { id = value; }
            }
    
            private string password;
    
            public string Password
            {
                get { return password; }
                set { password = value; }
            }
        }
    }

在窗体上拖拽一个Button按钮，然后双击进其点击事件。

private void button7_Click(object sender, EventArgs e)
            {
                DateTime begin = DateTime.Now;
                Console.WriteLine("二进制压缩开始" + begin.ToString("yyyy-MM-dd HH:mm:ss"));
                //初始化数据
                for (int i = 0; i < 10000; i++)
                {
                    personList.Add(new Person(i,"密码"+i));
                }
                try
                {
                    //创建内存流对象
                    MemoryStream ms = new MemoryStream();                 
                    //序列化对象
                    BinaryFormatter formatter = new BinaryFormatter();
                    formatter.Serialize(ms, this.personList);
                    //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();                                                            
                   FileStream fs = File.Create(@"E:\testdata1\Record3.zip");//创建文件
                    //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Record3.data文件
                   ZipEntry entry = new ZipEntry("Record3.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("二进制压缩结束" + end.ToString("yyyy-MM-dd HH:mm:ss"));
                Console.WriteLine("共花费 " + ts.TotalSeconds);
            }

具体使用见注释。
