概述

一般來說winform應(yīng)用程序解決這個問題起來時很容易的，web應(yīng)用程序就麻煩一點了。你必要有聯(lián)機型居民身份證閱讀器一個。

實現(xiàn)方式

1、新建一個winform控件項目ReadCardControl，添加一個主類ReadIDCard

  1. private bool  ReadIDCard() 
  2.      { 
  3.          try 
  4.          { 
  5.              BLL.API.SynIDCardAPI.IDCardData CardMsg = new BLL.API.SynIDCardAPI.IDCardData(); 
  6.              int nRet, nPort; 
  7.              byte[] pucIIN = new byte[4]; 
  8.              byte[] pucSN = new byte[8]; 
  9.              nPort = Convert.ToInt32(1001); 
  10.              if (BLL.API.SynIDCardAPI.Syn_OpenPort(nPort) == 0) 
  11.              { 
  12.                  if (BLL.API.SynIDCardAPI.Syn_SetMaxRFByte(nPort, 80, 0) == 0) 
  13.                  { 
  14.  
  15.                      nRet = BLL.API.SynIDCardAPI.Syn_StartFindIDCard(nPort, ref pucIIN[0], 0); 
  16.                      nRet = BLL.API.SynIDCardAPI.Syn_SelectIDCard(nPort, ref pucSN[0], 0); 
  17.                      nRet = BLL.API.SynIDCardAPI.Syn_ReadMsg(nPort, 0, ref CardMsg); 
  18.                      if (nRet == 0) 
  19.                      { 
  20.                          txtAddress.Text = CardMsg.Address; 
  21.                           
  22.                          txtBirthday.Text = CardMsg.Born; 
  23.                          txtCerticate.Text = CardMsg.IDCardNo; 
  24.                         
  25.                          txtIssuingAuthoriy.Text = CardMsg.GrantDept; 
  26.                          txtNames.Text = CardMsg.Name; 
  27.                          txtNation.Text = Xw.Common.Helper.NationHelper.GetNationByNO(CardMsg.Nation); 
  28.                          txtSex.Text = CardMsg.Sex == "1" ? "男" : "女"; 
  29.                          picMan.Image = Image.FromFile(CardMsg.PhotoFileName); 
  30.                          //lblMsg.Text = "讀卡成功"; 
  31.                          return true; 
  32.                      } 
  33.                      else 
  34.                      { 
  35.                          lblMsg.Text = "請放卡: 讀取身份證信息錯誤"; 
  36.                          return false; 
  37.                      } 
  38.                  } 
  39.              } 
  40.              else 
  41.              { 
  42.                  lblMsg.Text = "打開端口失敗"; 
  43.                  return false; 
  44.              } 
  45.              return true; 
  46.          } 
  47.          catch (Exception ex) 
  48.          { 
  49.              Xw.Common.Helper.LogHelper.WriteErrorToLog(ex.Message); 
  50.              return false; 
  51.          } 
  52.      } 

2、聲明DllImport，調(diào)用動態(tài)鏈接庫

  1. public  class SynIDCardAPI 
  2.     { 
  3.         #region IDCardData 
  4.         [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)]
