存储身份证数据的类：
[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)] public struct IDCardData { [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)] [JsonProperty("name")] public string Name; //姓名 [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 6)] [JsonProperty("sex")] public string Sex; //性别 [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 20)] [JsonProperty("nation")] public string Nation; //名族 [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 18)] [JsonProperty("born")] public string Born; //出生日期 [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 72)] [JsonProperty("address")] public string Address; //住址 [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 38)] [JsonProperty("idCardNo")] public string IDCardNo; //身份证号 [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)] [JsonProperty("grantDept")] public string GrantDept; //发证机关 [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 18)] [JsonProperty("userLifeBegin")] public string UserLifeBegin; // 有效开始日期 [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 18)] [JsonProperty("userLifeEnd")] public string UserLifeEnd; // 有效截止日期 [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 38)] [JsonIgnore] public string reserved; // 保留 [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 255)] [JsonProperty("photeBase64Str")] public string PhotoFileName; // 照片路径 }
具体方法：
private static string _imageDirPath = Path.Combine(CommonConst.DirPath, "CardImg"); public static bool Read(ref IDCardData idCardData) { if (!Directory.Exists(_imageDirPath)) { Directory.CreateDirectory(_imageDirPath); } bool isTrue = false; try { //先查找读卡器 int i, nRet; i = Syn_FindReader(); //只支持usb if (i > 1000) { var nPort = i; if (Syn_OpenPort(nPort) == 0) { Thread.Sleep(5); if (Syn_SetMaxRFByte(nPort, 80, 0) == 0) { Thread.Sleep(5); byte[] pucIIN = new byte[4]; byte[] pucSN = new byte[8]; IDCardData cardMsg = new IDCardData(); nRet = Syn_StartFindIDCard(nPort, ref pucIIN[0], 0); //找卡 nRet = Syn_SelectIDCard(nPort, ref pucSN[0], 0); //选卡 string cardStr = new string(‘ ‘, 256); //身份证基本信息返回长度为256 string imgMsg = new string(‘ ‘, 1024); //身份证图片信息返回长度为1024 IntPtr msg = Marshal.StringToHGlobalAnsi(cardStr); //身份证基本信息 IntPtr img = Marshal.StringToHGlobalAnsi(imgMsg); //身份证图片 uint mLen = 0; uint iLen = 0; nRet = Syn_ReadBaseMsg(nPort, msg, ref mLen, img, ref iLen, 0); if (nRet == 0) { Syn_ClosePort(nPort); string card = Marshal.PtrToStringUni(msg); char[] cartb = card.ToCharArray(); cardMsg.Name = (new string(cartb, 0, 15)).Trim(); cardMsg.Sex = new string(cartb, 15, 1); cardMsg.Nation = new string(cartb, 16, 2); cardMsg.Born = new string(cartb, 18, 8); cardMsg.Address = (new string(cartb, 26, 35)).Trim(); cardMsg.IDCardNo = new string(cartb, 61, 18); cardMsg.GrantDept = (new string(cartb, 79, 15)).Trim(); cardMsg.UserLifeBegin = new string(cartb, 94, 8); cardMsg.UserLifeEnd = new string(cartb, 102, 8); byte[] data=new byte[iLen]; Marshal.Copy(img,data,0,data.Length); cardMsg.PhotoFileName = GetImageBase64Str(data, cardMsg.IDCardNo); idCardData = cardMsg; isTrue = true; } } Syn_ClosePort(nPort); } } } catch (Exception e) { LogHelper.WriteLog("读取身份证失败", e); isTrue = false; } return isTrue; } private static string GetImageBase64Str(byte[] data, string idCardNo) { var wltFileName = Path.Combine(_imageDirPath, string.Format("{0}.wlt", idCardNo)); if (File.Exists(wltFileName)) { File.Delete(wltFileName); } using (FileStream fs = new FileStream(wltFileName, FileMode.Create)) { fs.Write(data, 0, data.Length); fs.Close(); } // Thread.Sleep(200); var nRet = GetBmp(wltFileName, 2); if (nRet == 1) { // Thread.Sleep(200); string bmpFileName = Path.Combine(_imageDirPath, string.Format("{0}.bmp", idCardNo)); if (File.Exists(bmpFileName)) { var str = GetFileBase64Str(bmpFileName); File.Delete(bmpFileName); return str; } } return string.Empty; } private static string GetFileBase64Str(string fileName) { using (MemoryStream ms = new MemoryStream()) { using (Bitmap bmp = new Bitmap(fileName)) { bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp); } byte[] arr1 = new byte[ms.Length]; ms.Position = 0; ms.Read(arr1, 0, (int) ms.Length); return Convert.ToBase64String(arr1); } using (FileStream fs=new FileStream(fileName,FileMode.Open)) { byte[] bt = new byte[fs.Length]; //调用read读取方法 fs.Read(bt, 0, bt.Length); return Convert.ToBase64String(bt); } }
最终结果是将信息存储IDCardData结构体中，图片信息转换为base64str。
注意：WltRS.dll一定要很新，我以前用的是2007年的，在转换头像的时候总是报错，找了一个新的，是2012年的，就好了。
