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

private bool ReadIDCard(){try{BLL.API.SynIDCardAPI.IDCardData CardMsg = new BLL.API.SynIDCardAPI.IDCardData();int nRet, nPort;byte[] pucIIN = new byte[4];byte[] pucSN = new byte[8];nPort = Convert.ToInt32(1001);if (BLL.API.SynIDCardAPI.Syn_OpenPort(nPort) == 0){if (BLL.API.SynIDCardAPI.Syn_SetMaxRFByte(nPort, 80, 0) == 0){nRet = BLL.API.SynIDCardAPI.Syn_StartFindIDCard(nPort, ref pucIIN[0], 0);nRet = BLL.API.SynIDCardAPI.Syn_SelectIDCard(nPort, ref pucSN[0], 0);nRet = BLL.API.SynIDCardAPI.Syn_ReadMsg(nPort, 0, ref CardMsg);if (nRet == 0){txtAddress.Text = CardMsg.Address;txtBirthday.Text = CardMsg.Born;txtCerticate.Text = CardMsg.IDCardNo;txtIssuingAuthoriy.Text = CardMsg.GrantDept;txtNames.Text = CardMsg.Name;txtNation.Text = Xw.Common.Helper.NationHelper.GetNationByNO(CardMsg.Nation);txtSex.Text = CardMsg.Sex == "1" ? "男" : "女";picMan.Image = Image.FromFile(CardMsg.PhotoFileName);//lblMsg.Text = "讀卡成功";return true;}else{lblMsg.Text = "請放卡: 讀取身份證信息錯誤";return false;}}}else{lblMsg.Text = "打開端口失敗";return false;}return true;}catch (Exception ex){Xw.Common.Helper.LogHelper.WriteErrorToLog(ex.Message);return false;}}

2、聲明DllImport，調(diào)用動態(tài)鏈接庫

public class SynIDCardAPI{#region IDCardData[StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)]public struct IDCardData{[MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)] //結(jié)構(gòu)中使用的字串，[]類似限定說明 說明此公共結(jié)構(gòu)傳輸?shù)椒峭泄艽a時封裝定義public string Name;

3、讀取顯示相關(guān)的信息

txtAddress.Text = CardMsg.Address;txtBirthday.Text = CardMsg.Born;txtCerticate.Text = CardMsg.IDCardNo;txtIssuingAuthoriy.Text = CardMsg.GrantDept;txtNames.Text = CardMsg.Name;txtNation.Text = Xw.Common.Helper.NationHelper.GetNationByNO(CardMsg.Nation);txtSex.Text = CardMsg.Sex == "1" ? "男" : "女";picMan.Image = Image.FromFile(CardMsg.PhotoFileName);//lblMsg.Text = "讀卡成功";return true;
