ftpwebrequest

问题 I have an application written in .NET 3.5 that uses FTP to upload/download files from a server. The app works fine but there are performance issues: It takes a lot of time to make connection to the FTP server. The FTP server is on a different network and has Windows 2003 Server (IIS FTP). When multiple files are queued for upload, the change from one file to another creates a new connection using FTPWebRequest and it takes a lot of time (around 8-10 seconds). Is is possible to re-use the

问题 I trying upload file to a directory on a FTP server. I used this method with FtpWebRequest . I would like to upload one file to a home directory for this user, but I always get the following error message: The requested URI is invalid for this FTP command. What can be problem? I tried use passive mode off, but it still the same. static void FtpUpload() { // Get the object used to communicate with the server.

问题 I need to use FtpWebRequest to put a file in a FTP directory. Before the upload, I would first like to know if this file exists. What method or property should I use to check if this file exists? 回答1: var request = (FtpWebRequest)WebRequest.Create ("ftp://ftp.domain.com/doesntexist.txt"); request.Credentials = new NetworkCredential("user", "pass"); request.Method = WebRequestMethods.Ftp.GetFileSize; try { FtpWebResponse response = (FtpWebResponse)request.GetResponse(); } catch (WebException

问题 I am using .NET 4 C#. I am trying to upload and then download a ZIP file to (my) server. For uploading I have using (WebClient client = new WebClient()) { FtpWebRequest request = (FtpWebRequest)WebRequest.Create(MyUrl); request.Method = WebRequestMethods.Ftp.UploadFile; request.EnableSsl = false; request.Credentials = new NetworkCredential(MyLogin, MyPassword); byte[] fileContents = null; using (StreamReader sourceStream = new StreamReader(LocalFilePath)) { fileContents = Encoding.UTF8

问题 I\'m creating a service to monitor FTP locations for new updates and require the ability to parse the response returned from a FtpWebRequest response using the WebRequestMethods.Ftp.ListDirectoryDetails method. It would be fairly easy if all responses followed the same format, but different FTP server software provide different response formats. For example one might return: 08-10-11 12:02PM <DIR> Version2 06-25-09 02:41PM 144700153 image34.gif 06-25-09 02:51PM 144700153 updates.txt 11-04-10

问题 General Info I\'m still in the process of learning C#. To help myself out, I\'m trying to create a program that will automatically synchronise all of my local projects with a folder on my FTP server. This so that whether I\'m at school or at home, I always have the same projects available to me. I know there are programs like Dropbox that already do this for me, but I figured creating something like that myself will teach me a lot along the way. The problem My first step towards my goal was

问题 I wonder if it\'s possible to have output log for my FTP client using FtpWebRequest . Something like this: [R] USER xxx [R] 331 Please specify the password.
