本文介绍了一个简单的 C# 应用程序，演示如何实现拨打电话和发送短信的功能。通过串口与设备交互，设置了短信发送的 PDU 模式，并实现了号码和文本内容的编码。

因为项目的需要，简简单单的做了个DEMO，能够打电话和发送短信，不是很完善，都可以举一反三！

代码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.IO.Ports;

namespace testPhoneInfo_Csharp
{
    public partial class frmMain : Form
    {
        public frmMain()
        {
            InitializeComponent();
            Form.CheckForIllegalCrossThreadCalls = false;
        }

        private void frmMain_Load(object sender, EventArgs e)
        {
            sp.Open();
        }

        private void btnPhone_Click(object sender, EventArgs e)
        {
            sp.WriteLine("ATD"+txtPhoneNum.Text .Trim ()+";"+"\r\n");
        }

        private void btnSendMsg_Click(object sender, EventArgs e)
        {
            sp.WriteLine("AT+CMGF=0"+"\r\n");//将短消息格式设置为PDU模式
            System.Threading.Thread.Sleep(300);
            sp.WriteLine("AT+CSCA=" + "+8613010314500" + "\r\n");
            System.Threading.Thread.Sleep(300);
            sp.WriteLine("AT+CMGS=0" + this.getLenght(txtMsg.Text.Trim()) + "\r\n");
            System.Threading.Thread.Sleep(500);
            sp.WriteLine("0011000D91" + this.reverserNumber(txtPhoneNum.Text.Trim()) + "000801" + this.contentEncoding(txtMsg.Text.Trim()) + Convert.ToChar(26).ToString());
        }
        //获取短信内容的字节数
        private string getLenght(string txt)
        {
            int i = 0;
            string s = "";
            i = txt.Length * 2;
            i += 15;
            s = i.ToString();
            return s;
        }
        //将手机号码转换为内存编码
        private string reverserNumber(string phone)
        {
            string str = "";
            //检查手机号码是否按照标准格式写，如果不是则补上
            if (phone.Substring(0, 2) != "86")
            {
                phone = string.Format("86{0}", phone);
            }
            char[] c = this.getChar(phone);
            for (int i = 0; i <= c.Length - 2; i += 2)
            {
                str += c[i + 1].ToString() + c[i].ToString();
            }
            return str;
        }
        //汉字解码为16进制
        private string contentEncoding(string content)
        {
            Encoding encodingUTF = System.Text.Encoding.BigEndianUnicode;
            string s = "";
            byte[] encodeByte = encodingUTF.GetBytes(content);
            for (int i = 0; i <= encodeByte.Length - 1;i++ )
            {
                s += BitConverter.ToString(encodeByte, i, 1);
            }
            s=string.Format ("{0:X2}{1}",s.Length /2,s);
            return s;
        }

        private char[] getChar(string phone)
        {
            if (phone.Length % 2 == 0)
            {
                return Convert.ToString(phone).ToCharArray();
            }
            else
            {
                return Convert.ToString(phone + "F").ToCharArray();
            }
        }

        private void sp_DataReceived(object sender, SerialDataReceivedEventArgs e)
        {
            txtReturnData.Text += sp.ReadExisting()+"\r\n";
        }
    }
}

其实都很简单，大家一看都会了！
