1.利用Rar压缩文件
/// <summary> /// 使用Rar压缩文件 /// </summary> /// <param name="fromFilePath">待压缩文件路径</param> /// <param name="rarFilePath">压缩后的文件路径</param> /// <returns>返回压缩结果</returns> public string RarFile(string fromFilePath, string rarFilePath) { try { //Rar程序安装目录 var fileName = @"C:\Program Files\WinRAR\rar.exe"; //命令行参数 var arguments = " a " + rarFilePath + " " + fromFilePath; var startInfo = new ProcessStartInfo(); startInfo.FileName = fileName; startInfo.Arguments = arguments; startInfo.WindowStyle = ProcessWindowStyle.Hidden; //打包文件存放目录 var dir = Path.GetDirectoryName(fromFilePath); if (dir != null) { startInfo.WorkingDirectory = dir; var process = new Process { StartInfo = startInfo }; process.StartInfo.RedirectStandardOutput = true; process.StartInfo.RedirectStandardError = true; process.StartInfo.UseShellExecute = false; process.StartInfo.CreateNoWindow = true; process.Start(); process.WaitForExit(); var output = process.StandardOutput.ReadToEnd(); var errMsg = process.StandardError.ReadToEnd(); process.Close(); //rar可能是中文版或英文版 if (output.IndexOf("完成", StringComparison.Ordinal) > -1 || output.ToLower().IndexOf("done", StringComparison.Ordinal) > -1) { return "完成"; } } return "文件所在目录不存在"; } catch (Exception ex) { return ex.Message; } } 调用方法：//将文件压缩到同级目录 var fromFile = ""; var dir = Path.GetDirectoryName(fromFile); var name = Path.GetFileNameWithoutExtension(fromFile); var tofile = dir.Combine(name + ".zip"); var result = RarFile(fromFile, tofile);
2.通过FTP上传文件
/// <summary> /// Ftp上传文件 /// </summary> /// <param name="localFile">本地文件路径</param> /// <param name="ftpServer">ftp服务器地址</param> /// <param name="ftpUserName">ftp用户名</param> /// <param name="ftpPassword">ftp用户密码</param> /// <returns></returns> public string Upload(string localFile, string ftpServer, string ftpUserName, string ftpPassword) { if (File.Exists(localFile)) { var fileInfo = new FileInfo(localFile); using (var fileStream = fileInfo.OpenRead()) { var length = fileStream.Length; var request = (FtpWebRequest)WebRequest.Create("ftp://" + ftpServer + "/" + fileInfo.Name); request.Credentials = new NetworkCredential(ftpUserName, ftpPassword); request.Method = WebRequestMethods.Ftp.UploadFile; request.UseBinary = true; request.ContentLength = length; request.Timeout = 10 * 1000; try { var stream = request.GetRequestStream(); var BufferLength = 1024 * 1024; //1M var b = new byte[BufferLength]; int i; while ((i = fileStream.Read(b, 0, BufferLength)) > 0) { stream.Write(b, 0, i); } stream.Close(); stream.Dispose(); return "上传完毕"; } catch (Exception ex) { return ex.Message; } } } return "本地文件不存在!"; }通过以上方式，再做个定时任务，可以将服务器文件定期备份到指定的ftp上。
