FileSystemWatcher监控文件的问题

嘶吼的蚂蚁 2012-09-03 05:26:28

公司有个项目用FileSystemWatcher监控某个目录的文件夹中的文件改变，但是在我拷贝一个新的文件夹到该目录下的时候，新文件夹中的文件没有监控到！



        public Form1()

        {

            InitializeComponent();

            if (!File.Exists(music_folderPath))

                Directory.CreateDirectory(music_folderPath);

            if (!File.Exists(movie_folderPath))

                Directory.CreateDirectory(movie_folderPath);



            watcherMusic.Path = music_folderPath;

            watcherMusic.IncludeSubdirectories = true;



            watcherMusic.Created += new FileSystemEventHandler(watcherMusic_Changed);

            watcherMusic.Deleted += new FileSystemEventHandler(watcherMusic_Changed);

            watcherMusic.Renamed += new RenamedEventHandler(watcherMusic_Renamed);

            watcherMusic.EnableRaisingEvents = true;



            watcherMovie.Path = movie_folderPath;

            watcherMovie.IncludeSubdirectories = true;

            watcherMovie.Created += new FileSystemEventHandler(watcherMovie_Changed);

            watcherMovie.Deleted += new FileSystemEventHandler(watcherMovie_Changed);

            watcherMovie.Renamed += new RenamedEventHandler(watcherMovie_Renamed);

            watcherMovie.EnableRaisingEvents = true;



            this.Hide();

            this.Opacity = 0;

            this.ShowInTaskbar = false;

        }
