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;
