ArrayList alWorkPoint = new ArrayList();

alWorkPoint.clear();

SaveFileDialog dialog = new SaveFileDialog();
 dialog.Title = "save";
 dialog.InitialDirectory = ".\\";
 dialog.FileName = "new.txt";
 dialog.Filter = "txt file (*.*)|*.txt";
 if (dialog.ShowDialog() == DialogResult.OK)
   {
       StreamWriter filew = new StreamWriter((dialog.FileName));
       DecoderListView();
       for (int i = 0; i < alWorkPoint.Count; i++)
       {
           filew.WriteLine(alWorkPoint[i].ToString());
       }
       filew.Close();
       MessageBox.Show("save ok");
