概述
一般来说winform应用程序解决这个问题起来时很容易的，web应用程序就麻烦一点了。你必要有联机型居民身份证阅读器一个。
实现方式
1、新建一个winform控件项目ReadCardControl，添加一个主类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 = "读卡成功";
- return true;
- }
- else
- {
- lblMsg.Text = "请放卡: 读取身份证信息错误";
- return false;
- }
- }
- }
- else
- {
- lblMsg.Text = "打开端口失败";
- return false;
- }
- return true;
- }
- catch (Exception ex)
- {
- Xw.Common.Helper.LogHelper.WriteErrorToLog(ex.Message);
- return false;
- }
- }
2、声明DllImport，调用动态链接库
- public class SynIDCardAPI
- {
- #region IDCardData
- [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Ansi, Pack = 1)]
- public struct IDCardData
- {
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)] //结构中使用的字串，[]类似限定说明 说明此公共结构传输到非托管代码时封装定义
- public string Name; //姓名
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 6)]
- public string Sex; //性别
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 20)]
- public string Nation; //名族
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 18)]
- public string Born; //出生日期
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 72)]
- public string Address; //住址
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 38)]
- public string IDCardNo; //身份证号
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 32)]
- public string GrantDept; //发证机关
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 18)]
- public string UserLifeBegin; // 有效开始日期
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 18)]
- public string UserLifeEnd; // 有效截止日期
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 38)]
- public string reserved; // 保留
- [MarshalAs(UnmanagedType.ByValTStr, SizeConst = 255)]
- public string PhotoFileName; // 照片路径
- }
- #endregion

3、读取显示相关的信息
- 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 = "读卡成功";
- return true;
