Question

我正在使用此示例http://www.codeproject.com/KB/cs/SMS.aspx创建一个将通过手机发送短信的应用程序。当我制作一个GUI win应用程序时，一切正常，但当我尝试将其转换为Windows服务应用程序（无GUI）在后台工作时，它告诉我没有连接手机。

以下是两个非常简单的例子：

GUI app

using System;
using System.Windows.Forms;
using GsmComm.GsmCommunication;
using GsmComm.PduConverter;

namespace SMS.Forms
{
    public partial class SendSMS : Form
    {
        SmsSubmitPdu pdu;
        private int port;
        private int baudrate;
        private int timeout;

        public SendSMS()
        {
            InitializeComponent();

            //phone connection
            port = 3;
            baudrate = 115200;
            timeout = 300;
        }

        private void button1_Click(object sender, EventArgs e)
        {
            GsmCommMain comm = new GsmCommMain(port, baudrate, timeout);

            try
            {
                comm.Open();

                //send sms
                pdu = new SmsSubmitPdu("Test msg", "0xxxxxxxxx", "");
                comm.SendMessage(pdu);

                comm.Close();
            }
            catch (Exception ex)
            {
                MessageBox.Show(this, "Connection error: " + ex.Message, "Connection setup", MessageBoxButtons.OK, MessageBoxIcon.Warning);
                return;
            }
            MessageBox.Show(this, "Successfully connected to the phone.", "Connection setup", MessageBoxButtons.OK, MessageBoxIcon.Information);
        }
    }
}

WIN服务

using System;
using System.Diagnostics;
using System.ServiceProcess;
using GsmComm.GsmCommunication;
using GsmComm.PduConverter;

namespace SMS
{
    public partial class SendSMS : ServiceBase
    {

        SmsSubmitPdu pdu;

        //logs
        private string sSource;
        private string sLog;
        private string sEvent;

        private int port;
        private int baudrate;
        private int timeout;

        public SendSMS()
        {
            InitializeComponent();

            //event logs
            sSource = "SendSMS";
            sLog = "SMS";
            if (!EventLog.SourceExists(sSource))
                EventLog.CreateEventSource(sSource, sLog);


            //phone connection
            port = 3;
            baudrate = 115200;
            timeout = 300;
        }

        protected override void OnStart(string[] args)
        {
            //logs
            sEvent = "SMS service started";
            EventLog.WriteEntry(sSource, sEvent);

            GsmCommMain comm = new GsmCommMain(port, baudrate, timeout);

            try
            {
                comm.Open();
                while (!comm.IsConnected())
                {
                    sEvent = "Phone not connected";
                    EventLog.WriteEntry(sSource, sEvent);
                    comm.Close();
                    return;
                }

                //send sms
                pdu = new SmsSubmitPdu("Test msg", "0xxxxxxxxx", "");
                comm.SendMessage(pdu);

                comm.Close();
            }
            catch (Exception ex)
            {
                sEvent = "Not done " + ex.Message;
                EventLog.WriteEntry(sSource, sEvent);
                return;
            }
            finally
            {
                comm.Close();
            }
        }

        protected override void OnStop()
        {
            //logs
            sEvent = "SMS service stopped";
            EventLog.WriteEntry(sSource, sEvent);
        }
    }
}

当我启动服务时，它会将“Phone not connected”写入事件日志。我有什么想法我做错了吗？或者至少如何查明错误...

感谢。

您需要创建计时器类的实例，并检查手机是否按特定间隔连接，而不是在onStart事件中编写电话连接代码。您可以在onstart事件中启动计时器。
