filesystemwatcher

问题 When a file is being copied to the file watcher folder, how can I identify whether the file is completely copied and ready to use? Because I am getting multiple events during file copy. (The file is copied via another program using File.Copy.) 回答1: 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. Once the file isn't

问题 I'm trying to create a watch folder on a network share that simply copies files (300mb-20gb) in size to a destination folder. The FileSystemWatcher and subscription works great with small files (i.e. 1-3kb). However, larger files do not copy. I do see a copy is triggered in the verbose stream, but no file is copied to the destination folder. $Folder = "\\10.11.233.91\vol_tx01\delivered_media" $Filter = "*.mxf" $destination = "C:\Users\Leeds TX 11\Desktop\support\Testy" $Watcher = New-Object

问题 I have managed to get the Service working, along with the FileSystemEventHandler inserting into a text file, but this now needs to be changed to insert into a database and a text file. using System; using System.Collections.Generic; using System.ComponentModel; using System.Configuration; using System.Data; using System.Data.SqlClient; using System.Diagnostics; using System.IO; using System.Linq; using System.ServiceProcess; using System.Text; using System.Threading.Tasks; using System.Timers

问题 I have written file watcher functionality to focus on particular directory activities. I can read all events like creating ,deleting ,renaming and changing the file/folder. But i don't know how to handle cut and paste scenario, since for "cut" results as firing delete event i and "paste" results as create event firing. how to handle cut and paste scenario? Any advice on this. 回答1: Here ya go! Monitor the clipboard for cut/copy/paste operations :) 回答2: On a delete, you could store the file

问题 I need FileSystemWatcher, that can observing same specific paths, and specific extensions. But the paths could by dozens, hundreds or maybe thousand (hope not :P), the same with extensions. The paths and ext are added by user. Creating hundreds of FileSystemWatcher it's not good idea, isn't it? So - how to do it? Is it possible to watch/observing every device (HDDs, SD flash, pendrives, etc.)? Will it be efficient? I don't think so... . Every changing Windows log file, scanning file by

问题 Okay, Probably going to be seen as an extremely amature post here, I'm not really skilled in VB or much of a programmer but i'm on a "learn by doing" drive. I'm developing an application which creates directories for a user, and tracks the directories created and the changes to these directories using FileSystemWatcher. I've got this little snippet so far (Updated in answer you your comments Jimi): Private Sub of Button_Click: watchfolder = New System.IO.FileSystemWatcher() watchfolder.Path =

问题 I've created simple WPF control to monitor changes in log file. I used FileSystemWatcher to watch specific file. My configuration: Directory = System.IO.Path.GetDirectoryName(logFileFullPath); Filter = System.IO.Path.GetFileName(logFileFullPath); NotifyFilter = (NotifyFilters.LastWrite | NotifyFilters.Size); EnableRaisingEvents = true; The problem is that changes are displayed only after refreshing the directory manually or opening log file. I use RollingFileAppender in my log4net

问题 I want my endpoint to send out an event whenever a detects a file in a specific folder is dropped. I was able to get it to work by using a class which implements IWantToRunWhenBusStartsAndStops, which in turn sets up a FileSystemWatcher to monitor the given folder. My questions is, is this the best way to go about this with nservicebus or am I missing something that may cause me trouble down the line? Here is my code: public class FileSystem : IWantToRunWhenBusStartsAndStops { private

问题 I need to create a listener in C# that will watch a shared folder (UNC path) and copy the files with a specific extension (*.json) to a target folder when they arrive. The files can be delayed for about half a minute. The folder is never empty. Problems: The files will arrive in a new sub folder, FileSystemWatcher can't be used since it can't listen to sub folders in a shared folder. The files needs to be copied and left in the folder, so we need to assure that the same file isn't copied more

问题 I have a windows service (and verified the code by creating a similar WinForms application) where the NotifyFilter doesn't work. As soon as I remove that line of code, the service works fine and I can see the event-handler fire in the WinForms application. All I'm doing is dropping a text file into the input directory for the FileSystemWatcher to kick off the watcher_FileChanged delegate. When I have the _watcher.NotifyFilter = NotifyFilters.CreationTime; in there, it doesn't work. When I
