我正在使用串行端口通过 GSM/调制解调器发送短信。我的代码正在处理单个短信。当我尝试批量发送短信时出现问题。然后不会发送短信，也不会产生异常。
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO.Ports;
using System.ComponentModel;
using System.Windows.Forms;
namespace program.cs
{
public class Class1
{
public string[] strarray = new string[10];
SerialPort serialport1 = new SerialPort();
string com = "COM8";
int mybaudrate = 9600;
//this.strarray =System.IO.Ports.SerialPort.GetPortNames();
public void getports()
{
this.strarray = System.IO.Ports.SerialPort.GetPortNames();
}
public bool connetport()
{
bool Isopen;
serialport1.Close();
try
{
if (!this.serialport1.IsOpen)
{
this.serialport1.PortName = com;
this.serialport1.Open();
this.serialport1.BaudRate = mybaudrate;
this.serialport1.StopBits = System.IO.Ports.StopBits.One;
this.serialport1.Parity = System.IO.Ports.Parity.None;
this.serialport1.Handshake = System.IO.Ports.Handshake.None;
Isopen= serialport1.IsOpen;
}
Isopen = true;
}
catch (Exception ex)
{
Isopen = false;
throw ex;
}
return Isopen;
}
public void sendsms()
{
try
{
if (this.serialport1.IsOpen)
{
// to send bulk sms
serialport1.BaseStream.Flush();
int loop = 0;
int howmany = 0;
howmany = 200;
while (loop < howmany)
{
System.Threading.Thread.Sleep(3500);
string cb = char.ConvertFromUtf32(26);
this.serialport1.Write("AT+CMGF=1\r");
this.serialport1.Write("AT+CSCA=servicecenter\r
\n");//Ufone Service Center
this.serialport1.Write("AT+CMGS=\"" + "03468916446" + "\"\r\n");//
this.serialport1.Write("hello" + cb);//message text
message sending
System.Threading.Thread.Sleep(3500);
loop++;
}
MessageBox.Show("Message Sent Number" + loop);
serialport1.Close();
}
}
catch (Exception ex)
{
serialport1.Close();
throw ex;
}
}
}
}
上面的Class1是用来连接和发送短信的
主程序代码
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
bool check;
Class1 obj = new Class1();
private void button1_Click(object sender, EventArgs e)
{
check = obj.connetport();
MessageBox.Show("Connecton Status" + check);
obj.sendsms();
MessageBox.Show("have completed");
}
}
我花了很多时间来解决这个问题，但没有成功。您的帮助将不胜感激
