    {
      //
      if (e.Button==MouseButtons.Right)
      {
        // 得到屏幕鼠标的坐标，转换为列表控件的坐标标
        m_MBRpt = listView1.PointToClient(Control.MousePosition);
      }

      {
        MessageBox.Show("没有选中交易信息！", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
        return;
      }

      // 得到屏幕鼠标的坐标，转换为列表控件的坐标标(在鼠标按下时就去处理并保存)
      //Point pt = listView1.PointToClient(m_MBRpt);

      ListViewItem lstrow = listView1.GetItemAt(m_MBRpt.X, m_MBRpt.Y);
      System.Windows.Forms.ListViewItem.ListViewSubItem lstcol = lstrow.GetSubItemAt(m_MBRpt.X, m_MBRpt.Y);
      string strText = lstcol.Text;
      //设置到粘贴板
      SetClipboardText(strText);

    }
