Windows mobile 下读取手机SIM卡信息

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;
}
}
