打开文件夹及关闭文件夹

  //打开文件夹
            //System.Diagnostics.Process.Start("explorer.exe", lblSelete.Text + @"\");
            //Thread.Sleep(5000);         
            //截图
            //Thread.Sleep(5000);   
            //关闭所有文件夹
            //System.Diagnostics.Process[] myPs;
            //myPs = System.Diagnostics.Process.GetProcesses();
            //foreach (System.Diagnostics.Process p in myPs)
            //{
            //    if (p.ProcessName.ToLower() == "explorer".ToLower())
            //    {
            //        try
