将win应用转换为win服务

Question

我正在使用这个示例http://www.codeproject.com/KB/cs/SMS.aspx来制作一个应用程序，它将通过移动电话发送短信。当我创建一个GUI win应用程序时，一切运行正常，但当我尝试将其转换为windows服务应用程序(无GUI)以在后台工作时，它告诉我没有连接电话。

下面是两个非常简单的例子：

GUI应用程序

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);
        }
    }
}

赢得服务

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);
        }
    }
}

当我启动该服务时，它会在事件日志中写入"Phone not connected“。你知道我做错了什么吗？或者至少如何定位错误..。

谢谢。

您不需要在onStart事件中编写电话连接代码，而是需要创建timer类的实例，并检查电话是否按特定时间间隔连接。您可以在onstart事件中启动计时器。
