FileSystemWatcher多触发问题

Question

FileSystemWatcher

Answer 1

不用这么复杂吧？
 FileSystemWatcher mywatcher = null;
        public void watch()
        {            mywatcher = new FileSystemWatcher();
            mywatcher.Path = @"F:\doc";
            //mywatcher.Path=@"E:\zxj";
            mywatcher.NotifyFilter = NotifyFilters.LastWrite;
            //mywatcher.Filter = "test.txt";
            mywatcher.Changed += new FileSystemEventHandler(OnChanged);
            mywatcher.EnableRaisingEvents = true;
        }        private void OnChanged(object source, FileSystemEventArgs e)
        {
            mywatcher.EnableRaisingEvents = false;
            if (e.ChangeType == WatcherChangeTypes.Changed)
            {
                MessageBox.Show("File is Modified!");
            }
            mywatcher.EnableRaisingEvents = true;
            mywatcher.Changed -= new FileSystemEventHandler(OnChanged);
        }
这样好像就可以了啊。
