Download FileWatcherDemo - 813.5 KB View Part 2 of this article series. This eliminates duplicates in your processing directive and allows some time for the copy to finish. You need to collect average copy times in your environment and set the memory cache timeout to be at least as long as the shortest lock time on a new file. Implement a try\catch loop with a timeout for access.Implement the Memor圜ache pattern seen in this question: A robust solution for FileSystemWatcher firing events multiple times.I have solved this issue with two features: An agent is configured with the FTP plug-in and as an FTP server to enable. We'll want to wait a bit between polls, if the file isn't ready. The process is, first the file watcher starts to run, it waits for the. File isn't ready yet, so we need to keep on waiting until it is. Using(stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None)) Modifying the code in that answer does the trick, so I ended up using something like this: private void WaitForFile(FileInfo file) There just doesn't seem to be any way around that, though, so it's what I ended up using. I plan on using the command NLIST because I dont need file size information, and there will be no sub-directories in the folder. Unfortunately, the only way to do that is to wrap a try/catch around opening the file, which makes me cringe - having to use try/catch is always painful. Once the file isn't being written to any more, the lock will succeed. StreamReader reader = new StreamReader(Response.When I ran into this problem, the best solution I came up with was to continually try to get an exclusive lock on the file while the file is being written, the locking attempt will fail, essentially the method in this answer. ad esempio FileWatcher o i summenzionati Mamont e FileMare. Request = (FtpWebRequest)FtpWebRequest.Create(new Uri(FtpFolderPath)) ) e, se presenti, appuntati anche la password e il nome utente necessari per accedere a quest’ultimo. Private string GetFilesList(string FtpFolderPath, string UserName, string Password) ![]() Since the'. While (s.Read(Buffer, 0, BufferSize) != -1) The FileSystemWatcher only watches for '.ftpComplete' files, and strips that off the end to know the actual file uploaded. Using (FileStream fs = new FileStream(Path.Combine(FileSystemLocation, FileName), FileMode.CreateNew, FileAccess.ReadWrite)) Using (Stream s = Response.GetResponseStream()) Response = (FtpWebResponse)Request.GetResponse() Request.Credentials = new NetworkCredential(UserName, Password) It then runs a Task that can act on the watched file by downloading it, zipping, unzipping, or even sending it as an email attachment. FTP Watcher monitors an FTP or FTPS server's directory for changes in file content, size or file count. Request = (FtpWebRequest)FtpWebRequest.Create(new Uri(Path.Combine(FtpLocation, FileName))) FTP Watcher is integral part of freeware version of Automation Workshop. In the first round, just print number of files foundĬonsole.WriteLine("Found already exist.", FileName)) "/remote/path", "*.*", EnumerationOptions.AllDirectories) SessionOptions sessionOptions = new SessionOptions See the article Watching for changes in SFTP/FTP server: // Setup session options NET assembly, you can use the Session.EnumerateRemoteFiles method. NET FTP client, the FtpWebRequest does not. It's actually rather easy to implement, if you use an FTP client library that supports recursive listing of a remote tree. You cannot use the FileSystemWatcher or any other way, because the FTP protocol does not have any API to notify a client about changes in the remote directory.Īll you can do is to periodically iterate the remote tree and find changes.
