![]() ![]() We can do that by using the following method. But there are times when we need to monitor multiple directories and if any changes are available, invoke a given method. We then add a System.IO.FileSystemEventHandler delegate to the Created event so that control can be delegated to the FileCreated method of our FileInputMonitor class whenever a new file is created. In a previous example, I showed how to use the FileSystemWatcher class to monitor a directory. If the file is designated for our application, the ProcessFile method is called to process the file. When the FileCreated method is executed, we check whether the new file is what our application wants via the Name property of the System.IO.FileSystemEventArgs instance. In order to enable the FileSystemWatcher instance to notify our application when files are created in the folder, we must first set its EnableRaisingEvents property to true. Checking whether an expected file is ready for processing. When an instance of FileInputMonitor is created, we also create an instance of System.IO.FileSystemWatcher class, passing it the directory path of the folder to monitor.Īfter creating an instance of the FileSystemWatcher, we proceed to configure it. ![]() Monitoring whether new files are created in a folder with System.IO.FileSystemWatcher } // end private void ProcessFile(String fileName) StreamReader reader = new StreamReader(inputFileStream) InputFileStream = new FileStream(fileName, Private void ProcessFile(String fileName) } // end public void FileCreated(Object sender, FileSystemEventArgs e) Private void FileCreated(Object sender, FileSystemEventArgs e) when there are files created at the folder.įileSystemWatcher.Created += new FileSystemEventHandler(FileCreated) Instruct the file system watcher to call the FileCreated method Related Tutorials Watch for an image folder Watch with thread event handler Monitoring a Directory for Content Changes Watch a directory (or tree) for. = + "toTechcoil" įileSystemWatcher = new FileSystemWatcher(folderToWatchFor) įileSystemWatcher.EnableRaisingEvents = true First prepare rvice file Unit DescriptionStart the script Service Typeoneshot ExecStart/path/to/your/script next go to mymonitor.

A program may need to process new files (often written to the directory by other programs). The following FileInputMonitor class is an implementation for the sample use case. This class monitors a directory for changes.
