filesystemwatcher

问题 I need to watch a directory for image files(jpeg,png,tif,gif,bmp) and process new files placed there.Im trying to implement this using FileSystemWatcher private void watch() { FileSystemWatcher watcher = new FileSystemWatcher(); watcher.Path = path; watcher.Filter = "*.*"; watcher.Changed += new FileSystemEventHandler(OnChanged); watcher.EnableRaisingEvents = true; } But how can i make sure that the file is copied in full and there is no handle locking the file before trying to open it? 回答1:

问题 My program needs to monitor multiple locations, but trigger the same code for each location. As a single FileSystemWatcher can't monitor multiple locations, but is it possible to create multiple instances of it and pass in a folder path for each? I can't hard code each FileSystemWatcher as more and more locations will need to be added in time and this needs to be done by the end users, as it is highly impractical for me to have to manually hard code a new FileSystemWatcher each time. So my

问题 This is a follow up to this question. I followed the accepted answer and thought I was satisfied with the results but ran into a roadblock. The Setup I'm running my C# program from the server that monitors a directory. Any time a file is modified, FileSystemWatcher triggers an event that causes the program to check the security audit logs (which have been turned on, see previous question's solution). The Problem My problem is that when I check the security logs after a remote user has

问题 I want to create a filewatcher and do the below flow using PowerShell: Watch for file in folderA (.zip) → move the file to folderB as (.zip) → unzip the moved file in folderC (with same name) → and trigger a batch file → do the same for more incoming .zip files. I checked a related question to this in StackOverflow but I need some more help. My PowerShell script is as below (I am using PowerShell ISE): while ($true) { $watcher = New-Object System.IO.FileSystemWatcher $watcher.Path = "D:

问题 When i create a watcher i want to add an object to it that i can read during the watchers watcher_Created event? 回答1: You can just capture it in an anonymous delegate: object o; var watcher = new FileSystemWatcher(); watcher.Created += (sender, e) => { Console.WriteLine(o); // handle created event }; Here, o represents the object that you want to capture (it doesn't have to be typed as object ). Note that this is effectively the same as class Foo { private readonly object o; public Foo(object

问题 I have created File system watcher for console application. it is working flawless. unliess you press 'q' its keep listning the folder for adding files and display name of the files when found. public void FileWatcher() { while (true) { FileSystemWatcher watcher = new FileSystemWatcher(); watcher.Path = @"C:\\WATCH-FOLDER"; watcher.IncludeSubdirectories = true; watcher.NotifyFilter = NotifyFilters.Attributes | NotifyFilters.CreationTime | NotifyFilters.DirectoryName | NotifyFilters.FileName |

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 5 years ago . I'm doing some task in my team's project. I did my first work that is how to recognize and get file from the USB which contains a register file. And I have researched how to prevent some action like: copy, paste, delete files from the USB which don't contain a register file. Until

问题 I have a service that opens multiple watchers to watch multiple folders. After watching folders for a certain amount of time I get the "The network bios command limit has been reached". As I read on here this is caused by having more long term requests than allowed. I believe this occurs due to the below error handling code i have, which is triggered by the watchers error event. This starts a new instance of the watcher by calling the WatchFile method again. I believe this leaves the old now

问题 I would like to remove duplicate entries from a queue in an efficient way. The queue has a custom class with DateTime and FullPath and a few other things private Queue<MyCustomClass> SharedQueue; The DateTime in the class is the timestamp when inserted into the queue. The logic I would like to use is as following: Remove duplicates from the queue if the FullPath is identical within a 4 second window (i.e. if added to queue within 4 seconds of a duplicate fullpath). I have the events that I

问题 I'm building a Windows Service that uses FileSystemWatcher, and runs in the background. I don't want to keep on uninstalling and installing the service every time I want to debug, so would like to do most of my development in a normal program before moving it into a service. But I'm quite new to this, and when I run it, it just runs through the block and exits. What would be a good way to keep the program running? 回答1: http://einaregilsson.com/run-windows-service-as-a-console-program/ I've
