filesystemwatcher

问题 For example, I can catch the Delete event for various files in a folder tree, but how would I go about determining which user caused the delete to happen? I couldn't find anything obvious in the MSDN documentation for FileSystemWatcher, so maybe it is just not possible. I'd be curious if there is a solution however. 回答1: This isn't currently possible with the current implementations of the FileSystemWatcher as it does not receive this type of information when a file is deleted, or anything

问题 I have added a watcher like this: watcher = new FileSystemWatcher(LOGFILES, "*.log"); watcher.NotifyFilter = NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.FileName; // Add event handlers. watcher.Changed += new FileSystemEventHandler(OnChanged); watcher.Created += new FileSystemEventHandler(OnChanged); watcher.Deleted += new FileSystemEventHandler(OnChanged); watcher.Renamed += new RenamedEventHandler(OnRenamed); // Begin watching. watcher.EnableRaisingEvents = true; and

问题 I know that the class FileSystemWatcher does not work on windows 8. Why are FileSystemWatcher Attribute changes detected on Windows 7 but not Windows 8? Anyways I need to know when a file is changed within a directory. For example I have dropbox installed on my computer and the moment I update a file it starts synchronizing. How does dropbox knows when a file has changed in windows 8? I already tried this solution in c++ http://msdn.microsoft.com/en-us/library/aa365261 and I have the same

问题 i have code below to tracking file changes on a dedicate folder Path path = Paths.get("f:\\logs"); WatchService watchService = FileSystems.getDefault().newWatchService(); WatchKey key = path.register(watchService, StandardWatchEventKinds.ENTRY_CREATE); while (true) { final WatchKey watchKey = watchService.take(); for (WatchEvent<?> watchEvent : key.pollEvents()) { WatchEvent.Kind<?> kind = watchEvent.kind(); if (kind == StandardWatchEventKinds.ENTRY_CREATE) { WatchEvent<Path> eventPath =

问题 I need to see when a file is written to a directory. This directory is on a mapped network drive on a Windows 2003 server. If I copy files to this directory on the server, it works. If I write files remotely, it does not work. What can I do to make it work when files are written remotely? I would like to keep this as an event notification, but will change to a polling method if needed. If thats the correct way to do it, I need some best practice advice. Any detail I can get on how Windows'

问题 I'm a beginner in C# and I'm stuck at this problem. I'm creating a service, that watches for incoming files, and when the file comes, I will call a .bat file to do some processing. The problem with the code below is, I copy the file into the watched folder for the first time it works, the second time I copy the file into the watched folder, it does not react anymore. It is running as a Windows service and it is running all the time. It used to work, I'm not sure what I'm missing. Hope someone

问题 Is there a way to set a credential for a filesystemwatcher object? The application runs on a different user that doesnt have access to directory on network machine but i want to give credentials to filesystemwatcher object so it can listen that directory. Is it doable? 回答1: No. Just make sure that your application runs under an account that has the correct privileges to access the resources you want to access.

问题 This is my first time using FileSystemWatcher, but it's not working. It doesn't trigger when a file is created in the monitored paths. My goal is to monitor changes in the Program File directories. I will compare files copied against an online list (which I download). I'm not finished with that part yet [what it will do if it finds a match]. What am I doing wrong? I've also noticed some say that FSW is glitchy or has issues. If you think I should use something else, let me know. Imports

问题 Using the .NET FileSystemWatcher http://msdn.microsoft.com/en-us/library/system.io.filesystemwatcher.aspx to monitor a directory full of files for : Changed; Created; Deleted; Renamed events . What's the minimum the rights the Account running the FileSystemWatcher needs over the directory it's watching ? It seems like it would be READ but I can't find that documented anywhere. Thanks 回答1: The underlying API is ReadDirectoryChangesW. The only thing mentioned in the MSDN Library article for it

问题 I have a question: How do I determine whether a folder has finished copying from one location to another? At the moment my FileSystemWatcher triggers several events as soon as a file within the directory being copied. What I want though, is one single event to be triggered when all the files within that folder has been successfully copied. My code right now looks like this: static void Main(string[] args) { String path = @"D:\Music"; FileSystemWatcher mWatcher = new FileSystemWatcher();
