使用华为加密狗发送短信 [英] Send SMS USing huawei dongle

问题描述

亲爱的朋友



我正在尝试发送短信使用华为加密狗，现在我只能发送短信当用户从组合中选择正确的com端口号在表单加载事件中加载的框，



现在我的问题如何使组合框加载huawei加密狗连接的唯一端口号？



这个我已完成的代码

 使用系统; 
 使用 System.Collections.Generic; 
 使用 System.Threading; 
 使用 System.IO.Ports; 
 使用 System.Windows.Forms; 
 使用 System.Management; 
 使用 System.Management.Instrumentation; 
 
 命名空间 gi 
 {
  public   partial   class  Form1：Form 
 {
  public  Form1（）
 {
 InitializeComponent（）; 
} 
 SerialPort s; 
  private   void  button1_Click（ object  sender，EventArgs e）
 {
 
  string  comport = cboPorts.Text; 
 GetPort（comport）; 
} 
  public   void  GetPort（ string  comport）
 {
  //   if（this.s == null） 
 {
  this  .s =  new  SerialPort（ ）; 
  this  .s.PortName = comport; 
  this  .s.Open（）; 
  this  .s.BaudRate =  9600 ; 
  this  .s.Parity = Parity.None; 
  this  .s.DataBits =  8 ; 
  this  .s.StopBits = StopBits.One; 
  //   this.s.Handshake = Handshake.RequestToSend;  
  this  .s.DtrEnable =  true ; 
 此 .s.RtsEnable =  true ; 
  //   this.s.RtsEnable = true;  
  this  .s.NewLine = System.Environment.NewLine; 
  this  .s.WriteLine（  AT  +（ char ）（ 13 ））; 
  //   string tt = s.ReadLine（）;  
  //   if（s.ReadLine（）！=AT / r / r） 
 {
 Thread.Sleep（ 2000 ）; 
  this  .s.WriteLine（  AT + CMGF = 1 +（ char ）（ 13 ））; 
 Thread.Sleep（ 3000 ）; 
  this  .s.WriteLine（  AT + CMGS = \ +  9916518522  +   \）; 
 Thread.Sleep（ 5000 ）; 
  this  .s.WriteLine（ > ; +   le +（ char ）（ 26 ））; 
  this  .s.Close（）; 
 MessageBox.Show（ 已发送）; 
} 
  //   else  
  //   { 
  //   MessageBox.Show（Dervice Nt）;  
  //  }  
} 
} 
 私有  void  Form1_Load（  object  sender，EventArgs e）
 {
  string  [] ports = SerialPort。 GetPortNames（）; 
 
 
  foreach （ string  port  in  ports）
 {
 cboPorts.Items.Add（port）; 
} 
 
 
} 
} 
} 

解决方案

< blockquote>而不是选择手动使用for循环并通过发送每个com端口进行检查&如果com端口不包含加密狗，则在try catch中捕获它并且不显示消息。

Dear Friends

I am trying to send SMS Using huawei dongle, now i am able to send SMS only When User Select the correct com port number from the combo box which are loaded at the form load event,

Now My Question How Can I make the Combo box Load the only port number which huawei dongle is connected?

This My Code Which I have Done

using System;
using System.Collections.Generic;
using System.Threading;
using System.IO.Ports;
using System.Windows.Forms;
using System.Management;
using System.Management.Instrumentation;

namespace gi
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        SerialPort s;
        private void button1_Click(object sender, EventArgs e)
        {

            string comport = cboPorts.Text;
            GetPort(comport);
        }
        public void GetPort(string comport)
        {
           // if (this.s == null)
            {
                this.s = new SerialPort();
                this.s.PortName = comport;
                this.s.Open();
                this.s.BaudRate = 9600;
                this.s.Parity = Parity.None;
                this.s.DataBits = 8;
                this.s.StopBits = StopBits.One;
                //this.s.Handshake = Handshake.RequestToSend;
                this.s.DtrEnable = true;
                this.s.RtsEnable = true;
                //this.s.RtsEnable = true;
                this.s.NewLine = System.Environment.NewLine;
                this.s.WriteLine("AT" + (char)(13));
                //string tt = s.ReadLine();
               // if(s.ReadLine()!="AT/r/r")
                {
                    Thread.Sleep(2000);
                    this.s.WriteLine("AT+CMGF=1" + (char)(13));
                    Thread.Sleep(3000);
                    this.s.WriteLine("AT+CMGS=\"" + 9916518522 + "\"");
                    Thread.Sleep(5000);
                    this.s.WriteLine(">" + "le" + (char)(26));
                    this.s.Close();
                    MessageBox.Show("Sent");
                }
                //else
                //{
                //    MessageBox.Show("Dervice Nt");
                //}
            }
        }
        private void Form1_Load(object sender, EventArgs e)
        {
            string[] ports = SerialPort.GetPortNames();


            foreach (string port in ports)
            {
                cboPorts.Items.Add(port);
            }


        }
    }
}

解决方案

instead of selecting manually use for loop & check by sending on every com port & if the com port does not consists the dongle catch it in try catch and do not show a message.
