我正试图在C#控制台应用程序中下载FTP文件,但即使我现在的路径是正确的,我总是收到一个错误,说明550文件未找到。
I am trying to download a file usng FTP within a C# console application, but even though I now the paths are correct I always get an error saying "550 file not found".
有什么办法返回当前路径(一旦连接到服务器)?
Is there any way, to return the current path (once connected to the server)?
// lade datei von FTP server string ftpfullpath = "ftp://" + Properties.Settings.Default.FTP_Server + Properties.Settings.Default.FTP_Pfad + "/" + Properties.Settings.Default.FTP_Dateiname; Console.WriteLine("Starte Download von: " + ftpfullpath); using (WebClient request = new WebClient()) { request.Credentials = new NetworkCredential(Properties.Settings.Default.FTP_User, Properties.Settings.Default.FTP_Passwort); byte[] fileData = request.DownloadData(ftpfullpath); using (FileStream file = File.Create(@path + "/tmp/" + Properties.Settings.Default.FTP_Dateiname)) { file.Write(fileData, 0, fileData.Length); file.Close(); } Console.WriteLine("Download abgeschlossen!"); }编辑 我的错误。修复了文件路径,仍然得到相同的错误。但是如果我连接FileZilla是确切的文件路径。
EDIT My mistake. Fixed the filepath, still getting the same error. But if I connect with FileZilla that's the exact file path.
推荐答案最后通过使用System.Net.FtpClient( netftp.codeplex/releases/view/95632 ),并使用以下内容代码
Finally found a solution by using System.Net.FtpClient (netftp.codeplex/releases/view/95632) and using the following code.
// aktueller pfad string apppath = Directory.GetCurrentDirectory(); Console.WriteLine("Bereite Download von FTP Server vor!"); using (var ftpClient = new FtpClient()) { ftpClient.Host = Properties.Settings.Default.FTP_Server; ftpClient.Credentials = new NetworkCredential(Properties.Settings.Default.FTP_User, Properties.Settings.Default.FTP_Passwort); var destinationDirectory = apppath + "\\Input"; ftpClient.Connect(); var destinationPath = string.Format(@"{0}\{1}", destinationDirectory, Properties.Settings.Default.FTP_Dateiname); Console.WriteLine("Starte Download von " + Properties.Settings.Default.FTP_Dateiname + " nach " + destinationPath); using (var ftpStream = ftpClient.OpenRead(Properties.Settings.Default.FTP_Pfad + "/" + Properties.Settings.Default.FTP_Dateiname)) using (var fileStream = File.Create(destinationPath , (int)ftpStream.Length)) { var buffer = new byte[8 * 1024]; int count; while ((count = ftpStream.Read(buffer, 0, buffer.Length)) > 0) { fileStream.Write(buffer, 0, count); } } }更多推荐
