本文实例讲述了C#使用WinRar命令进行压缩和解压缩操作的实现方法。分享给大家供大家参考，具体如下：

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Diagnostics; using System.IO; public partial class Zip : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } //压缩文件 protected void Button1_Click(object sender, EventArgs e) { ProcessStartInfo startinfo = new ProcessStartInfo(); ; Process process = new Process(); string rarName = "1.rar"; //压缩后文件名 string path = @"C:images"; //待压缩打包文件夹 string rarPath = @"C:zip"; //压缩后存放文件夹 string rarexe = @"c:Program FilesWinRARWinRAR.exe"; //WinRAR安装位置 try { //压缩命令，相当于在要压缩的文件夹(path)上点右键->WinRAR->添加到压缩文件->输入压缩文件名(rarName) string cmd = string.Format("a {0} {1} -r", rarName, path); startinfo.FileName = rarexe; startinfo.Arguments = cmd; //设置命令参数 startinfo.WindowStyle = ProcessWindowStyle.Hidden; //隐藏 WinRAR 窗口 startinfo.WorkingDirectory = rarPath; process.StartInfo = startinfo; process.Start(); process.WaitForExit(); //无限期等待进程 winrar.exe 退出 if (process.HasExited) { MSCL.JsHelper.Alert("压缩成功！", Page); } } catch (Exception ex) { MSCL.JsHelper.Alert(ex.Message, Page); } finally { process.Dispose(); process.Close(); } } //解压文件 protected void Button2_Click(object sender, EventArgs e) { ProcessStartInfo startinfo = new ProcessStartInfo(); ; Process process = new Process(); string rarName = "1.rar"; //将要解压缩的 .rar 文件名（包括后缀） string path = @"C:images1"; //文件解压路径（绝对） string rarPath = @"C:zip"; //将要解压缩的 .rar 文件的存放目录（绝对路径） string rarexe = @"c:Program FilesWinRARWinRAR.exe"; //WinRAR安装位置 try { //解压缩命令，相当于在要压缩文件(rarName)上点右键->WinRAR->解压到当前文件夹 string cmd = string.Format("x {0} {1} -y", rarName, path); startinfo.FileName = rarexe; startinfo.Arguments = cmd; //设置命令参数 startinfo.WindowStyle = ProcessWindowStyle.Hidden; //隐藏 WinRAR 窗口 startinfo.WorkingDirectory = rarPath; process.StartInfo = startinfo; process.Start(); process.WaitForExit(); //无限期等待进程 winrar.exe 退出 if (process.HasExited) { MSCL.JsHelper.Alert("解压缩成功！", Page); } } catch (Exception ex) { MSCL.JsHelper.Alert(ex.Message, Page); } finally { process.Dispose(); process.Close(); } } }

希望本文所述对大家C#程序设计有所帮助。
