c# - 发送大量短信时，批量短信应用程序挂起

Question

我使用 GsmComm 库、Oracle 数据库和 Devexpress 创建了简单的群发短信应用程序。我发送了很多消息(超过 25 条消息)我的应用程序挂起。我认为是因为过程太多。该场景，当用户发送消息时，它将存储到数据库(OUTBOX 表)，然后用户单击发件箱表单上的按钮，如果消息发送成功，它将存储到数据库(SENTMESSAGE 表)并删除 OUTBOX 表中发送成功的消息。当消息正在处理发送用户无法点击另一个按钮或菜单，但发送完成后，应用程序再次正常，用户可以点击许多菜单。我读了一些文章，如果使用 Gammu 是可能的，因为它是第三方应用程序，可以作为服务运行来发送和接收消息，但我需要它在 gsmcomm 库中。

有关详细信息，这是我的代码:

//SEND BULK SMS MORE THAN 30 MESSAGE APPLICATION HANG
if (CommSetting.comm.IsConnected() == true)
{
    int i;
    for (i = 0; i < gridView1.DataRowCount; i++)
    {
        string pesan = gridView1.GetRowCellValue(i,"MESSAGE").ToString();
        string ttd = lblTandaTangan.Text;
        string msg = pesan + Environment.NewLine + Environment.NewLine + ttd;  //SENT MESSAGE USING SIGNATURE

    var listPhoneNumber = new List<string>();
    listPhoneNumber.Add(gridView1.GetRowCellValue(i, "PHONENUMBER").ToString());

    foreach (var phoneNumber in listPhoneNumber)
    {
        var pdu = new SmsSubmitPdu(msg, phoneNumber, string.Empty);
        CommSetting.comm.SendMessage(pdu);

        //---------------STORE TO ORACLE DB--------------------
        if (koneksi_manual.con.State == ConnectionState.Open)
        {
            koneksi_manual.con.Close();
        }
        koneksi_manual.con.Open();

        OracleCommand cmd = new OracleCommand();
        cmd.CommandText = @"INSERT INTO MESSAGESENT (ID, DATE, TIME, PHONENUMBER, MESSAGE) VALUES 
                        (SQ_MESSAGESENT.NEXTVAL, '" + DateTime.Now + "', TO_DATE('" + DateTime.Now + "', 'dd/MM/yyyy hh24:mi:ss'), '"
                            + gridView1.GetRowCellValue(i, "PHONENUMBER") + "', '" + pesan.Replace("'", "''") + "', '" + Program.IDUser + "')";// <= Use gridView1.GetRowCellValue to get the cell value.
        cmd.Connection = koneksi_manual.con;
        cmd.ExecuteNonQuery();

        //Sleeps system for 1000ms for refreshing GSM Modem
        System.Threading.Thread.Sleep(1000);

        //DELETE MESSAGE SENT FROM OUTBOX
        var obj = gridView1.GetRowCellValue(i, "ID");

        OracleCommand cmd2 = new OracleCommand();
        cmd2.CommandText = "DELETE FROM OUTBOX WHERE ID = '" + obj + "'";
        cmd2.Connection = koneksi_manual.con;
        cmd2.ExecuteNonQuery();
    }
    MessageBox.Show("Message Sent", "Notif");
  }
}

我希望用户在发送消息时能够单击我的应用程序中的另一个菜单。我不知道如何解决这个问题，也许任何人都可以给我一个建议和任何概念，我将非常感激。谢谢..

你好尝试在这里使用线程

Control.CheckForIllegalCrossThreadCalls = false;
 Private Void BtnSend_Click(Object Sender,EventArg e)
    {
      Thread th = new Thread(new ThreadStart(SendMSM));
    }



 Private void SendMSM()
    {
    if (CommSetting.comm.IsConnected() == true)
    {
        int i;
        for (i = 0; i < gridView1.DataRowCount; i++)
        {
            string pesan = gridView1.GetRowCellValue(i,"MESSAGE").ToString();
            string ttd = lblTandaTangan.Text;
            string msg = pesan + Environment.NewLine + Environment.NewLine + ttd;  //SENT MESSAGE USING SIGNATURE

        var listPhoneNumber = new List<string>();
        listPhoneNumber.Add(gridView1.GetRowCellValue(i, "PHONENUMBER").ToString());

        foreach (var phoneNumber in listPhoneNumber)
        {
            var pdu = new SmsSubmitPdu(msg, phoneNumber, string.Empty);
            CommSetting.comm.SendMessage(pdu);

            //---------------STORE TO ORACLE DB--------------------
            if (koneksi_manual.con.State == ConnectionState.Open)
            {
                koneksi_manual.con.Close();
            }
            koneksi_manual.con.Open();

            OracleCommand cmd = new OracleCommand();
            cmd.CommandText = @"INSERT INTO MESSAGESENT (ID, DATE, TIME, PHONENUMBER, MESSAGE) VALUES 
                            (SQ_MESSAGESENT.NEXTVAL, '" + DateTime.Now + "', TO_DATE('" + DateTime.Now + "', 'dd/MM/yyyy hh24:mi:ss'), '"
                                + gridView1.GetRowCellValue(i, "PHONENUMBER") + "', '" + pesan.Replace("'", "''") + "', '" + Program.IDUser + "')";// <= Use gridView1.GetRowCellValue to get the cell value.
            cmd.Connection = koneksi_manual.con;
            cmd.ExecuteNonQuery();

            //Sleeps system for 1000ms for refreshing GSM Modem
            System.Threading.Thread.Sleep(1000);

            //DELETE MESSAGE SENT FROM OUTBOX
            var obj = gridView1.GetRowCellValue(i, "ID");

            OracleCommand cmd2 = new OracleCommand();
            cmd2.CommandText = "DELETE FROM OUTBOX WHERE ID = '" + obj + "'";
            cmd2.Connection = koneksi_manual.con;
            cmd2.ExecuteNonQuery();
        }
        MessageBox.Show("Message Sent", "Notif");
      }
    }
