写了一个代码，上传文件然后压缩成rar，调试下可以压缩，网站发布了就不能压缩~

[哩个名字肯定无人用]

RT！比较急，在线等。
可能是打开winrar的路径问题，我写的代码是绝对路径 如 @"C:\Program Files \WinRAR\WinRAR.exe"

压缩干嘛要调用exe工具呢？ICSharpCode.SharpZipLib可以直接用啊

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 Files\WinRAR\WinRAR.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(); } 代码例如这样，是个例子！调试下可以的，网站发布了不行了，string rarexe = @"c:\Program Files\WinRAR\WinRAR.exe"; //WinRAR安装位置------》这里应该没问题吧

有压缩两个文件的库吗？

[娃都会打酱油了]

压缩几个文件无所谓的，params string[] files这个就是要压缩的文件路径，最终都会压缩到一个zip文件里
