C# - Predict file system events on folder delete

Question

This is more a question about what\'s the best practice in implementing this.

I have a FileSystemWatcher which should inform me about User\'s changes on

Answer 1

Regarding the buffer overflow. The best way to solve it is to do the work in response to an event on another thread. I do it like this

// Queue of changed paths.
private readonly Queue mEventQueue = new Queue();

// add this as handler for filesystemwatcher events
public void FileSystemEvent(object source, FileSystemEventArgs e) {
    lock (mEventQueue) {
        if (!mEventQueue.Contains(e.FullPath)) {
            mEventQueue.Enqueue(e.FullPath);
            Monitor.Pulse(mEventQueue);
        }
    }
}

// start this on another thread
public void WatchLoop() {
    string path;
    while (true) {
        lock (mEventQueue) {
            while (mEventQueue.Count == 0)
                Monitor.Wait(mEventQueue);
            path = mEventQueue.Dequeue();
            if (path == null)
               break;
        }
        // do whatever you want to do
     }
}

That way I will never miss an event
