最近在忙一个移动警务的项目，需要获取SIM卡的信息，来做身份的验证。考虑到获取：国际移动设备识别码（IMEI：International Mobile Equipment Identification Number）和国际移动用户识别码（IMSI：International Mobile Subscriber Identification Number），读取这两个号码用到TAPI的lineGetGeneralInfo()函。在新版的OpenNetCF里没有发现对这个函数的封装（也许我没找到），于是到网上找了找，找到一个以前版本OpenNetCF里的：TapiLib.dll,包含对
Windows ce phone api 的封装（TAPI）,综合网上的一些资料，实现代码如下：public struct GeneralInfo { public string Manufacturer; public string Model; public string Revision; public string SerialNumber; public string SubscriberNumber; }
/// <summary> /// Tapi控制类 /// </summary> public class ControlTapi {
[DllImport("cellcore.dll")] private static extern int lineGetGeneralInfo(IntPtr hLigne,byte[]lpLineGeneralInfo );
/// <summary> /// 调用cellcore.dll获取sim卡的综合信息 /// </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> /// 获取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> /// 获取IMEI的号码 /// </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 的代码你可以去看看这里：http://www.peterfoot.net/RetrieveIMEIThroughTAPI.aspx另：1、环境：在vs2005+windows mobile 5.0 ＋多普达818测试通过。2、关于获取SIM卡的本机号码，你可以用：http://www.microsoft.com/china/msdn/archives/library/dnnetcomp/html/netcfPhoneAPI.asp，这里 提供的方法，不过这个方法需要安全认证，比较麻烦，具体认证的方式见：http://www.microsoft.com/china/MSDN/library/Mobility/pocketpc/2k3smartphonesecurity.mspx?pf=true。3、TapiLib.dll的下载地址：http://www.cnblogs.com/Files/xjb/TapiLib.rar4、参考资料：http://hucgy.bokee.com/3328836.html
