Windows mobile 下讀取手機SIM卡資訊

最近在忙一個移動警務的項目，需要擷取SIM卡的資訊，來做身份的驗證。考慮到擷取：國際行動裝置識別碼（IMEI：International Mobile Equipment Identification Number）和國際移動使用者識別碼（IMSI：International Mobile Subscriber Identification Number），讀取這兩個號碼用到TAPI的lineGetGeneralInfo()函。在新版的OpenNetCF裡沒有發現對這個函數的封裝（也許我沒找到），於是到網上找了找，找到一個以前版本OpenNetCF裡的：TapiLib.dll,包含對Windows ce phone api 的封裝（TAPI）,綜合網上的一些資料，實現代碼如下：

public struct GeneralInfo
    {
        public string Manufacturer;
        public string Model;
        public string Revision;
        public string SerialNumber;
        public string SubscriberNumber;
    }     /// <summary>
    /// Tapi控制類
    /// </summary>
    public class ControlTapi
    {         [DllImport("cellcore.dll")]
        private static extern int lineGetGeneralInfo(IntPtr hLigne,byte[]lpLineGeneralInfo );         /// <summary>
        /// 調用cellcore.dll擷取sim卡的綜合資訊
        /// </summary>
        /// <param name="l"></param>
        /// <returns></returns>
        private  GeneralInfo GetGeneralInfo(Line l)
        {
            GeneralInfo lgi = new GeneralInfo();
            byte[] buffer = new byte[512];
            BitConverter.GetBytes(512).CopyTo(buffer, 0);             if (lineGetGeneralInfo(l.hLine, buffer) != 0)
            {
                throw new System.ComponentModel.Win32Exception(System.Runtime.InteropServices.Marshal.GetLastWin32Error(), "TAPI Error: " + System.Runtime.InteropServices.Marshal.GetLastWin32Error().ToString("X"));
            }             int subscsize = BitConverter.ToInt32(buffer, 44);
            int subscoffset = BitConverter.ToInt32(buffer, 48);
            lgi.SubscriberNumber = System.Text.Encoding.Unicode.GetString(buffer, subscoffset, subscsize).ToString();
            lgi.SubscriberNumber = lgi.SubscriberNumber.Replace("/0", "");
            return lgi;         }                  /// <summary>
        /// 擷取sim卡的IMSI
        /// </summary>
        /// <returns></returns>
        public static string  GetIMSINumber()
        {
            string result = "";
            try
            {
                Tapi t = new Tapi();
                t.Initialize();
                Line l = t.CreateLine(0, LINEMEDIAMODE.INTERACTIVEVOICE, OpenNETCF.Tapi.LINECALLPRIVILEGE.MONITOR);
                ControlTapi ctapi = new ControlTapi();
                GeneralInfo gi = ctapi.GetGeneralInfo(l);
              
                result =  gi.SubscriberNumber;
                l.Dispose();
                t.Shutdown();             }
            catch// (Exception ex)
            {
                result = "";
            }             return result;         }         /// <summary>
        /// 擷取IMEI的號碼
        /// </summary>
        /// <returns></returns>
        public static string GetIMEINumber()
        {
            string result = "";
            try
            {
                Tapi t = new Tapi();
                t.Initialize();
                Line l = t.CreateLine(0, LINEMEDIAMODE.INTERACTIVEVOICE, OpenNETCF.Tapi.LINECALLPRIVILEGE.MONITOR);
                ControlTapi ctapi = new ControlTapi();
                GeneralInfo gi = ctapi.GetGeneralInfo(l);
                result = gi.SerialNumber;
                l.Dispose();
                t.Shutdown();             }
            catch// (Exception ex)
            {
                result = "";
            }             return result;
        }
    }

vb 的代碼你可以去看看這裡：http://www.peterfoot.net/RetrieveIMEIThroughTAPI.aspx

另：
1、環境：在vs2005+windows mobile 5.0 ＋多普達818測試通過。
2、
關於擷取SIM卡的本機號碼，你可以用：http://www.microsoft.com/china/msdn/archives/library/dnnetcomp/html/netcfPhoneAPI.asp，這裡 提供的方法，不過這個方法需要安全認證，比較麻煩，具體認證的方式見：http://www.microsoft.com/china/MSDN/library/Mobility/pocketpc/2k3smartphonesecurity.mspx?pf=true。
