我要回家想一想~

c#可以利用FileSystemWatcher監控檔案or資料夾的新增、更名、修改、刪除的動作

例：
            FileSystemWatcher watcher = new FileSystemWatcher();
            watcher.IncludeSubdirectories = true;
            watcher.Deleted += new FileSystemEventHandler(watcher_Deleted);
            watcher.Renamed += new RenamedEventHandler(watcher_Renamed);
            watcher.Changed += new FileSystemEventHandler(watcher_Changed);
            watcher.Created += new FileSystemEventHandler(watcher_Created);
            watcher.Path = "c:\\";
            watcher.Filter = "*.*";//監控所有文件，" *.txt " -->只監控.txt檔
            watcher.NotifyFilter = NotifyFilters.LastWrite |
                NotifyFilters.FileName |
                NotifyFilters.Size;

            //begin watching.
            watcher.EnableRaisingEvents = true;
