Windows mobile 下读取手机SIM卡信息

<script>function StorePage(){d=document;t=d.selection?(d.selection.type!='None'?d.selection.createRange().text:''):(d.getSelection?d.getSelection():'');void(keyit=window.open('http://www.365key.com/storeit.aspx?t='+escape(d.title)+'&u='+escape(d.location.href)+'&c='+escape(t),'keyit','scrollbars=no,width=475,height=575,left=75,top=20,status=no,resizable=yes'));keyit.focus();}</script>

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 phoneapi 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。
