问题 I have a program that needs to move a file from one directory to another on an FTP server. For example, the file is in: ftp://1.1.1.1/MAIN/Dir1 and I need to move the file to: ftp://1.1.1.1/MAIN/Dir2 I found a couple of articles recommending use of the Rename command, so I tried the following: Uri serverFile = new Uri(“ftp://1.1.1.1/MAIN/Dir1/MyFile.txt"); FtpWebRequest reqFTP= (FtpWebRequest)FtpWebRequest.Create(serverFile); reqFTP.Method = WebRequestMethods.Ftp.Rename; reqFTP.UseBinary =

问题 The following code is intended to retrieve a file via FTP. However, I'm getting an error with it. serverPath = "ftp://x.x.x.x/tmp/myfile.txt"; FtpWebRequest request = (FtpWebRequest)WebRequest.Create(serverPath); request.KeepAlive = true; request.UsePassive = true; request.UseBinary = true; request.Method = WebRequestMethods.Ftp.DownloadFile; request.Credentials = new NetworkCredential(username, password); // Read the file from the server & write to destination using (FtpWebResponse response

问题 I'm writing an application that syncs files over an FTP site. Right now it's working by connecting through regular FTP, but now our IT guys want to set this up over a secure FTPS connection. They provided me with a *.cr_ certificate file. If I open the file in notepad I see something like this (but with real keys not foobar obviously). -----BEGIN RSA PRIVATE FOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBAR FOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBARFOOBAR

问题 I have a C# code that basically uploads a file via FTP protocol (using FtpWebRequest ). I'd like, however, to first determine whether there is a working internet connection before trying to upload the file (since, if there isn't there is no point in trying, the software should just sleep for a time and check again). Is there an easy way to do it or should I just try to upload the file and in case it failed just try again, assuming the network connection was down? 回答1: Just use the plain

问题 I have written a console app to download files from an FTP and then upload to a different FTP location. The downloading on the files takes around 10 seconds, but the upload around 6 minutes. There are 256 files each around 5-30KB in size. So very small. The upload and download code is very similar, it iterates through all files in the directory then uploads. It is fairly simple as seen below, it iterates and uploads files to the ftp from the D:\LEV\ folder. EDIT: This is run on a Azure 'small

问题 How to change directory permissions on FTP server using FtpWebRequest/WebRequest (C#)? I've tried this, but without success (ftp unsupported method exception): ftpPath = ftpPath.Replace(dirname, ""); var request = (FtpWebRequest)WebRequest.Create(ftpPath); request.Credentials = new NetworkCredential(config.FtpUser, config.FtpPassword); request.UsePassive = true; request.UseBinary = true; request.Method = "CHMOD 777 " + dirname; using (var resp = (FtpWebResponse)request.GetResponse()) Any

问题 I want to show pdf files in browser which come from ftp. I found some code and I've tried it. The pdf is displayed in the browser but the file is empty. It has all of the pages as the original file but does not have the content on pages. string filename = Request.QueryString["view"]; FileInfo objFile = new FileInfo(filename); System.Net.FtpWebRequest request = (System.Net.FtpWebRequest)WebRequest.Create(new Uri("ftp://" + ftpServerIP + "/" + objFile.Name)); request.Credentials = new

问题 Is there any way to deal with situation when you need to get list of all directories on a FTP server, where the number of directories is so big that it takes too long to get it and operation fails with timeout? I wonder if there are some libraries that let you do that somehow? 回答1: Try something like this FtpWebRequest ftpRequest = (FtpWebRequest)WebRequest.Create(uri); ftpRequest.Credentials = new NetworkCredential("anonymous","yourName@SomeDomain.com");//replace with your Creds ftpRequest

问题 Im trying to check if a directory exists on an FTP server. Before you say "use ListDirectory" or "use PrintWorkingDirectory", they dont always work; for example, I tested if ftp://webserver/Logs existed and both told me it does when it actually doesnt. So Ive gone down the route of uploading a file to the directory and if successful, then the directory exists. The problem is, the below method doesnt work with GoDaddy's CentOS based server's running vsFTPd 2.0.7.2. Works fine with Microsoft

问题 I have an application that does the following: directory listing, download file, download all. I have an issue with getting the file names from WebRequestMethods.Ftp.ListDirectoryDetails. It seems that it is not possible to do so for every scenario. WebRequestMethods.Ftp.ListDirectoryDetails returns a lineItem in the following manner: "-rw-r--r-- 1 ftp ftp 39979 Aug 01 16:02 db to pc 2014-08-05 07-30-00.csv" I am using the first character to determine if it is a file or directory. Then I
