C#中文件监视的操作

1.            监视文件的操作用类FileSystemWatcher

   FileSystemWatcher fsw = new FileSystemWatcher();

        private void Form1_Load(object sender, EventArgs e)

        {

            //让¨?跨?线?程¨¬可¨¦以°?操¨´作Á¡Â控?件t

            Control.CheckForIllegalCrossThreadCalls =false;

            fsw.Path = @"E:\";

            //监¨¤视º¨®文?件t的Ì?类¤¨¤型¨ª

            fsw.Filter = "*.txt";

            //监¨¤视º¨®子Á¨®文?件t夹D

            fsw.IncludeSubdirectories = true;

            //监¨¤视º¨®文?件t创ä¡ä建¡§

            //created  deleted  renamed changed

            fsw.Created += new FileSystemEventHandler(fsw_Created);

            fsw.Changed += new FileSystemEventHandler(fsw_Changed);

            fsw.Deleted += new FileSystemEventHandler(fsw_Deleted);

            //启?用®?监¨¤视º¨®

            fsw.EnableRaisingEvents = true;

        }

 

        void fsw_Deleted(object sender,FileSystemEventArgs e)

        {

            listBox1.Items.Add(e.Name+"--"+e.ChangeType);

           

        }

 

        void fsw_Changed(object sender,FileSystemEventArgs e)

        {

            listBox1.Items.Add(e.Name + "--" + e.ChangeType);

            fsw.EnableRaisingEvents = false;

            fsw.EnableRaisingEvents = true;

        }

 

        void fsw_Created(object sender,FileSystemEventArgs e)

        {

            listBox1.Items.Add(e.Name + "--" + e.ChangeType);

        }
