ASP.NET程序读取二代身份证（附源码）

标签：

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。

这里我说说我的解决思路：

一、你必要有联机型居民身份证阅读器一个（带驱动光盘），这里我用的是精伦电子公司的iDR200,并有这个阅读器的开发接口说明。

二、新建一个winform控件项目ReadCardControl，添加一个主类ReadCard

1、  声明dll入口

        [DllImport("Sdtapi.dll")]

        private static extern int InitComm(int iPort);//初始化

        [DllImport("Sdtapi.dll")]

        private static extern int Authenticate();//卡认证

        [DllImport("Sdtapi.dll")]

        private static extern int ReadBaseInfos(StringBuilder Name, StringBuilder Gender, StringBuilder Folk, StringBuilder BirthDay, StringBuilder Code, StringBuilder Address, StringBuilder Agency, StringBuilder ExpireStart, StringBuilder ExpireEnd);//读取数据，推荐使用

        [DllImport("Sdtapi.dll")]

        private static extern int CloseComm();//关闭端口

        [DllImport("Sdtapi.dll")]

        private static extern int ReadBaseMsg(byte[] pMsg, ref int len);//读取数据，这里不用

        [DllImport("Sdtapi.dll")]

        private static extern int ReadBaseMsgW(byte[] pMsg, ref int len);//读取数据，这里不用

        [DllImport("kernel32.dll")]

        private static extern int Beep(int dwFreq, int dwDuration);//用来大吼一声

       2、读卡方法

        private string[] arrys = null;//声明用来保存身份证信息的数组

        public void OnTimer()

        {

            StringBuilder Name = new StringBuilder(31);

            StringBuilder Gender = new StringBuilder(3);

            StringBuilder Folk = new StringBuilder(10);

            StringBuilder BirthDay = new StringBuilder(9);

            StringBuilder Code = new StringBuilder(19);

            StringBuilder Address = new StringBuilder(71);

            StringBuilder Agency = new StringBuilder(31);

            StringBuilder ExpireStart = new StringBuilder(9);

            StringBuilder ExpireEnd = new StringBuilder(9);

            //int len = 0;

            //string[] temp;

            char[] param = { ‘\0‘ };

            byte[] pMsg = new byte[256];

            string[] baseinfo = new string[9];

            //打开端口

            int intOpenRet = InitComm(1001);

            if (intOpenRet != 1)

            {

                //SetText("阅读机具未连接", lblMsg);

                return;

            }

            //卡认证

            int intReadRet = Authenticate();

            if (intReadRet != 1)

            {

                //SetText("卡认证失败", lblMsg);

                CloseComm();

                return;

            }

            //ReadBaseInfos（推荐使用）

            int intReadBaseInfosRet = ReadBaseInfos(Name, Gender, Folk, BirthDay, Code, Address, Agency, ExpireStart, ExpireEnd);

            if (intReadBaseInfosRet != 1)

            {

                //SetText("读卡失败", lblMsg);

                CloseComm();

                return;

            }

            Beep(2047, 200);

            arrys = new string[10];

            arrys[0] = Code.ToString().Trim();

            arrys[1] = Name.ToString().Trim();

            arrys[2] = Gender.ToString().Trim();

            arrys[3] = Folk.ToString().Trim();

            arrys[4] = BirthDay.ToString().Trim();

            arrys[5] = Address.ToString().Trim();

            arrys[6] = Agency.ToString().Trim();

            arrys[7] = ExpireStart.ToString().Trim();

            arrys[8] = ExpireEnd.ToString().Trim();

            arrys[9] = System.IO.Directory.GetCurrentDirectory() + "\\photo.bmp";

            //SetText("读卡成功", lblMsg);

            //SetText("证件号码：" + Code.ToString(), label1);

            //SetText("姓名：" + Name.ToString(), label2);

            //SetText("性别：" + Gender.ToString(), label3);

            //SetText("民族：" + Folk.ToString(), label4);

            //SetText("出生日期：" + BirthDay.ToString(), label5);

            //SetText("地址：" + Address.ToString(), label6);

            //SetText("签发机关：" + Agency.ToString(), label7);

            //SetText("签发时间：" + ExpireStart.ToString(), label8);

            //SetText("有效截止时间：" + ExpireEnd.ToString(), label9);

            SetImage("photo.bmp", pictureBox1);

            CloseComm();

        }

2、  声明一个客户端调用的方法Test（这里没有直接用数组）

        public string Test()

        {

            string str = "";

            foreach (string s in arrys)

            {

                str += s + ",";

            }

            str = str.TrimEnd(‘,‘);

            return str;

}

三、将这个控件封装成activex组件

在ReadCard类的头部添加

[Guid("B9BB196C-5008-4156-840F-9FE37BA81502")]

若要实现客户端访问服务器端数据，则必须实现IObjectSafe接口

接口声明如下：

    [ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]

    [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]

    public interface IObjectSafe

    {

        [PreserveSig]

        void GetInterfaceSafeOptions(ref Guid id, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);

        [PreserveSig()]

        void SetInterfaceSafeOptions(ref Guid id, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);

}

            base.Dispose(disposing);
        }
