本文介绍了一种使用 C# 和 MSCOMM 控件实现短信发送的方法，详细展示了如何将手机号和短信内容转换为 PDU 格式，并通过 WAVECOM 短信猫设备完成短信的发送。

项目有一个功能要求发送短信,因为后台是ASP.NET的,所以就用C#写了一下,嘿嘿..项目要求只能发,不要收的,所以以下代码也只有发的啦,不好意思啊,用的是MSCOMM的控件,短信猫是WAVECOM的,大家参考一下:

  private string ConverPDU(string str) //手机号转PDU
  {
   int tl,ti;
   string ltem,rtem,ttem;
   ttem = "";
   tl = str.Length;
   if ((tl != 11) & (tl != 13))
     return "";
   if (tl == 11)
   {
    tl = tl + 2;
    str = "86" + str;
   }
   ti = 0;
   while (ti < tl)
   {
    ltem = str.Substring(ti,1);
    if ((ti+1) == tl)
     rtem ="F";
    else rtem = str.Substring(ti+1,1);
    ttem = ttem+rtem+ltem;
    ti=ti+2;
   }

   return ttem;
   }

  private string ConverUniCode(string str) //短信内容转PDU
  {
   Encoding encodingUTF = System.Text.Encoding.BigEndianUnicode;
   string s = null;
   byte [] encodedBytes = encodingUTF.GetBytes(str);
   for (int i =0;i < encodedBytes.Length;i++)
   {
    s += BitConverter.ToString(encodedBytes,i,1);
   }
   return s;
  }

  private bool Send(int Port,string Speed,string mobile,string msg) //发送短信
  {
   MSComm SMSComm = new MSCommLib.MSCommClass(); //微软的MSCOMM控件声明
   string prex;
   string pdu,pnum,pmsg,leng;

   string strIn = "";
   byte[] bytin;
   object objin;

string outstr;

   int len;
   prex = "0011000DA1";
   pnum = ConverPDU(mobile);
   pmsg = ConverUniCode(msg);
   len = pmsg.Length;
   len = len/2;
   leng = len.ToString("X");
   if (len < 16)
   {
    leng = "0"+ leng;
   }
   pdu = prex +pnum+"0008A7"+leng + pmsg;

   len = (pdu.Length/2)-1;
   try
   {
    SMSComm.CommPort = Convert.ToInt16(Port);
    if (SMSComm.PortOpen == true)
     SMSComm.PortOpen = false;

    SMSComm.Settings = Speed;
    SMSComm.Handshaking = MSCommLib.HandshakeConstants.comNone;
    SMSComm.InputLen = 0;
    SMSComm.InputMode = MSCommLib.InputModeConstants.comInputModeBinary;

    SMSComm.PortOpen = true;
    SMSComm.Output = "AT"+"/r/n";
    System.Threading.Thread.Sleep(1000);
    objin = SMSComm.Input;
    bytin = (byte[])objin;
    strIn= Encoding.ASCII.GetString(bytin);

    SMSComm.Output = "AT"+"/r/n";
    System.Threading.Thread.Sleep(1000);
    objin = SMSComm.Input;
    bytin = (byte[])objin;
    strIn= Encoding.ASCII.GetString(bytin);

    SMSComm.Output = "AT+CMGF=0"+"/r/n";
    System.Threading.Thread.Sleep(1000);
    objin = SMSComm.Input;
    bytin = (byte[])objin;
    strIn= Encoding.ASCII.GetString(bytin);

    SMSComm.Output = "AT+CNMI=2,1,0,1"+"/r/n";
    System.Threading.Thread.Sleep(1000);
    objin = SMSComm.Input;
    bytin = (byte[])objin;
    strIn= Encoding.ASCII.GetString(bytin);

    outstr = string.Format("AT+CMGS={0}/r",len);
    SMSComm.Output = outstr;
    System.Threading.Thread.Sleep(1000);
    objin = SMSComm.Input;
    bytin = (byte[])objin;
    strIn= Encoding.ASCII.GetString(bytin);
    SMSComm.InBufferCount = 0;
    SMSComm.OutBufferCount= 0;

    if(( strIn.Length > 0) && strIn.EndsWith("> "))
    {
     outstr = pdu.Trim()+"/x01a";
     SMSComm.Output = outstr.Trim();
     System.Threading.Thread.Sleep(5000);
     objin = SMSComm.Input;
     bytin = (byte[])objin;
     strIn= Encoding.ASCII.GetString(bytin);
     SMSComm.PortOpen = false;
     return true;
    }
    SMSComm.PortOpen = false;
    return false;
   }
   catch
   {
    SMSComm.PortOpen = false;
    return false;
   }
  }
