使用asp.net C＃通过GSM调制解调器发送短信 [英] Sending an SMS through a GSM modem using asp.net C#
本文介绍了使用asp.net C＃通过GSM调制解调器发送短信的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我一直在试图发送使用下面的code短信。在code通过连接到我的系统GSM调制解调器发送SMS。我已经正确地所在的COM端口。但还是消息是不会。任何人都可以找到什么地方出了错？这里是我的code。
使用系统;
使用System.Collections.Generic;
使用System.Linq的;
使用的System.Web;
使用System.Web.UI程序;
使用System.Web.UI.WebControls;
使用System.IO.Ports;公共部分类_Default：System.Web.UI.Page
{
的SerialPort SP =新的SerialPort（）;
保护无效的Page_Load（对象发件人，EventArgs的发送）
{
}
保护无效的button1_Click（对象发件人，EventArgs的发送）
{
尝试
{
SP.PortName =COM6;
SP.Open（）;
串PHONE_NUMBER;
PHONE_NUMBER = Char.ConvertFromUtf32（34）+myphonenumber+ Char.ConvertFromUtf32（34）;
SP.Write（AT + CMGF = 1+ Char.ConvertFromUtf32（13））;
SP.Write（AT + CMGS =+ PHONE_NUMBER + Char.ConvertFromUtf32（13））;
SP.Write（预约预订+ Char.ConvertFromUtf32（26）+ char.ConvertFromUtf32（13））;
SP.Close（）;
}
赶上（异常前）
{
的Response.Write（ex.ToString（））;
}
}
}
问题是我没有得到任何错误或异常。但还是短信不从调制解调器去。

I have been trying to send an SMS using the code below. The code sends an SMS through a GSM modem that is attached to my system. I have located the COM port correctly. But still the message isn't going. Can anyone find what went wrong? Here is my code.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.IO.Ports;
public partial class _Default : System.Web.UI.Page
{
SerialPort SP = new SerialPort();
protected void Page_Load(object sender, EventArgs e)
{
}
protected void Button1_Click(object sender, EventArgs e)
{
try
{
SP.PortName = "COM6";
SP.Open();
string phone_number;
phone_number = Char.ConvertFromUtf32(34) + "myphonenumber" + Char.ConvertFromUtf32(34);
SP.Write("AT+CMGF=1" + Char.ConvertFromUtf32(13));
SP.Write("AT+CMGS=" + phone_number + Char.ConvertFromUtf32(13));
SP.Write("Appointment booked" + Char.ConvertFromUtf32(26) + char.ConvertFromUtf32(13));
SP.Close();
}
catch (Exception ex)
{
Response.Write(ex.ToString());
}
}
}
The thing is I don't get any error or exception. But still SMS isn't going from the modem.
