标题: C# 窗口传值
From1 listview空间，查询按钮button，点击查询button跳转到From2.From2连接数据库查询数据，查询的结果返回到From1的listview。问题是我现在From1 listview什么值都没有得到。本人小白，所以各位最好详情点，谢谢。
         AseDataReader reader = null;
         Myplayer myplayer =new Myplayer();
         AseConnection conn = new AseConnection("Data Source='192.168.7.88'

ort='5000';UID='sa'

WD='';Database='GZMCH'; MaxPoolSize = 10;MinPoolSize = 5;ConnectionTimeout = 15;");
         try
         {
            conn.Open();
            // String sqlstr = "select phone,filename from call_phone_takelog_ago where logtime>" + starttime + " and logtime<" + endtime + "";
            String sqlstr = "exec sp_lylisten";
            AseCommand cmd = new AseCommand(sqlstr, conn);

            reader = cmd.ExecuteReader();
            while (reader.Read())
            {
                  ListViewItem lv = new ListViewItem();
                  lv.SubItems.Clear();
                  lv.SubItems.Add(Convert.ToString(reader["rowid"]));
                  lv.SubItems.Add(Convert.ToString(reader["phone"]));
                  lv.SubItems.Add(Convert.ToString(reader["filename"]));
                  myplayer.listView1.Items.Add(lv);
            }
         }
         catch (Exception ex)
         {
            MessageBox.Show(ex.ToString());
         }
         finally
         {
            this.Hide();
            reader.Close();
            conn.Close();
         }
