How to Monitor Directory for Created and Deleted file Changes
To monitor a directory for changes, follow this procedure:
1. Create a new FileSystemWatcher object, specifying the directory in the Path
property.
2. Register for the Created and Deleted events.
3. Turn on events by setting EnableRaisingEvents to true.
The following code snippet demonstrates this process:
create file system watcher object
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = @"c:\";
// Register for events like creation and deletion or other as per your requirement
watcher.Created +=
new FileSystemEventHandler(watcher_Changed);
watcher.Deleted +=
new FileSystemEventHandler(watcher_Changed);
// To Start Watching set the property enableraising events as true
watcher.EnableRaisingEvents = true;
// Event Handler about changing and deletion event to do the necessary code when particular change at event occure
static void watcher_Changed(object sender,
FileSystemEventArgs e)
{
Console.WriteLine("Directory changed({0}): {1}",
e.ChangeType,
e.FullPath);
}
The event handler simply reports each change found in the FileSystemEventArgs object that is sent to the event handler.
