How do you change directories using FtpWebRequest (.NET)?

由 亡梦爱人 提交于 2019-11-28 00:01:44
Can someone tell me how to change directories using FtpWebRequest? This seems like it should be an easy thing to do, but I'm not seeing it. EDIT I just want to add...I don't have my heart set on FtpWebRequest. If there's a better (easier) way to do FTP in .NET please let me know. Apparently there's no way to do it using a live connection, you need to change the uri to trick ftpwebrequest into using a different request (thanks Jon). So I'm looking for a 3rd party client... Some of the open source solutions I tried didn't work too well (kept crashing), but I found one open source solution that's

Using FTP to download each file *WHILE* getting the file list

由 社会主义新天地 提交于 2019-11-27 23:16:55
We need to get about 100 very small files from a remote FTP server using vb.net. Our company won't let us buy (or install) any 3rd party ftp libraries... so we are forced to use something like FtpWebRequest. (Or is there a better free, choice that is already a part of Visual Studio?) This method works, but it is VERY slow. (I assume because of the constant logging in/out.) Log in with user name and password. Get a file-list from the remote server. Log out Use that file-list to get each file separtely: Log in, get the file, log out. Log in 99 more times, get each file, log out each time.

Uploading files to FTP are corrupted once in destination

问题 I'm creating a simple drag-file-and-upload-automatically-to-ftp windows application and I'm using the MSDN code to upload the file to the FTP.

FtpWebRequest request = (FtpWebRequest)WebRequest.Create(String.Format("{0}{1}", FTP_PATH, filenameToUpload)); request.Method = WebRequestMethods.Ftp.UploadFile; // Options request.UseBinary = true; request.UsePassive = false; // FTP Credentials request
