本文介绍了一种使用 Ionip.ZIP.DLll 库进行文件压缩与解压缩的方法，包括压缩文件夹、解压指定文件及全部文件、从压缩包移除文件和向压缩包添加文件等功能，并提供了另一种利用 WinRAR 实现解压缩的方案。

法二：

1本地安装Win.rar程序

string strzipPath = path + "\\" + Program.filename.Replace("\0", ""); //带解压的zip
      System.Diagnostics.Process Process1 = new System.Diagnostics.Process();
   Process1.StartInfo.FileName = "Winrar.exe";
                                    Process1.StartInfo.CreateNoWindow = true;
                                    Process1.StartInfo.Arguments = " x -p123456 " + strzipPath + " " + path;
                                    Process1.Start();
path 解压到哪个路径，注意中间要有空格

x -p密码待解压zip 解压到哪个路径解压缩

a -p密码压缩到哪个文件压缩路径压缩
