This is because as soon as a new file is created in the directory being monitored (D:\IDG in our example), the FileSystemWatcher_Created event is triggered. You would observe that the name of the newly created file is displayed in the console window. Spurred by an article a while back in Game Developer Magazine, I decided to write a little cross platform library for detecting changes in files. FileWatcher library watches files while you play. Private static void FileSystemWatcher_Created(object sender, FileSystemEventArgs e)Ĭonsole.WriteLine("File created: ", e.Name) Īssuming that the directory named IDG is available on the D:\> drive of your system, run the console application and then create a new file in the IDG directory.

In essence, this starts the actual monitoring - you are informing FileSystemWatcher to start monitoring the path and raise appropriate events henceforth.įor each of the events that you have declared, you should have the respective event handler that gets executed when the event is triggered. Here's the source code of the event handlers that would be triggered as and when a change to the directory being monitored occurs. Files can be inserted on the command line or saved to a list file. Note how the events are declared and that the EnableRaisingEvents property of the file system watcher object is set to true to enable raising events when a change on the path being monitored occurs. FileWatcher 2.4: Continuously monitor a folder or group of folders for any new files, then trigger a custom action, such as running a second program with the new files. Private static void MonitorDirectory(string path)įileSystemWatcher fileSystemWatcher = new FileSystemWatcher() įileSystemWatcher.Created += FileSystemWatcher_Created įileSystemWatcher.Renamed += FileSystemWatcher_Renamed įileSystemWatcher.Deleted += FileSystemWatcher_Deleted įileSystemWatcher.EnableRaisingEvents = true The directory path is passed as an argument to the method. This method would be used to monitor a particular directory and raise events whenever a change occurs. The following code snippet shows how the MonitorDirectory method would look like.

You can build a Windows Service that uses the FileSystemWatcher class and sends out notifications as and when changes occur to the path being watched. Note that a better way to use the FileSystemWatcher class would be by using a Windows Service. Let's create a new console application project in Visual Studio to demonstrate how a typical file system watcher works. Renamed: This event is triggered when a file or a directory in the path being monitored is renamedĬreating a simple file system watcher in C#.Error: This event is triggered there is an error due to changes made in the path being monitored.Deleted: This event is triggered when a file or a directory in the path being monitored is deleted.Created: This event is triggered when a file or a directory in the path being monitored is created.Changed: This event is triggered when a file or a directory in the path being monitored is changed.The FileSystemWatcher raises the following events when changes occur to a directory that it is monitoring. In order for the FileSystemWatcher to work, you should specify a directory that needs to be monitored. It watches a file or a directory in your system for changes and triggers events when changes occur. Watcher.The FileSystemWatcher class in the System.IO namespace can be used to monitor changes to the file system. Watcher.NotifyFilter = NotifyFilters.LastWrite Watcher.Path = AbsoluteRequestQueue + _mac the proposed new way įileSystemWatcher watcher = new FileSystemWatcher() String _files = Directory.GetFiles("my root path" + _mac, "*.dat")

#FILEWATCHER HTTP HOW TO#
I was trying to test this but I could not see how to return the callback to the client when a file is 'found'. Net framework instead of the IIS process. Someone told me that if use a FileWatcher instead of a while(true) loop that the memory is placed on the. I have noticed running it his was the wp3 process climbs in memory usage. When there are files present or a time-out occurs the callback is returned to the client. In the I am checking for the existence of certain files which is in itself contained in a while(true) loop.
