一般來(lái)說(shuō)winform應(yīng)用程序解決這個(gè)問(wèn)題起來(lái)時(shí)很容易的，web應(yīng)用程序就麻煩一點(diǎn)了。

這里我說(shuō)說(shuō)我的解決思路：

一、你必要有聯(lián)機(jī)型居民身份證閱讀器一個(gè)（帶驅(qū)動(dòng)光盤(pán)），這里我用的是精倫電子公司的iDR200,并有這個(gè)閱讀器的開(kāi)發(fā)接口說(shuō)明。

二、新建一個(gè)winform控件項(xiàng)目ReadCardControl，添加一個(gè)主類(lèi)ReadCard

1、  聲明dll入口

        [DllImport("Sdtapi.dll")]

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

        [DllImport("Sdtapi.dll")]

        private static extern int Authenticate();//卡認(rèn)證

        [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);//讀取數(shù)據(jù)，推薦使用

        [DllImport("Sdtapi.dll")]

        private static extern int CloseComm();//關(guān)閉端口

        [DllImport("Sdtapi.dll")]

        private static extern int ReadBaseMsg(byte[] pMsg, ref int len);//讀取數(shù)據(jù)，這里不用

        [DllImport("Sdtapi.dll")]

        private static extern int ReadBaseMsgW(byte[] pMsg, ref int len);//讀取數(shù)據(jù)，這里不用

        [DllImport("kernel32.dll")]

        private static extern int Beep(int dwFreq, int dwDuration);//用來(lái)大吼一聲

       2、讀卡方法

        private string[] arrys = null;//聲明用來(lái)保存身份證信息的數(shù)組

        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];

            //打開(kāi)端口

            int intOpenRet = InitComm(1001);

            if (intOpenRet != 1)

            {

                //SetText("閱讀機(jī)具未連接", lblMsg);

                return;

            }

            //卡認(rèn)證

            int intReadRet = Authenticate();

            if (intReadRet != 1)

            {

                //SetText("卡認(rèn)證失敗", lblMsg);

                CloseComm();

                return;

            }

            //ReadBaseInfos（推薦使用）

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

            if (intReadBaseInfosRet != 1)

            {

                //SetText("讀卡失敗", 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("讀卡成功", lblMsg);

            //SetText("證件號(hào)碼：" Code.ToString(), label1);

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

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

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

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

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

            //SetText("簽發(fā)機(jī)關(guān)：" Agency.ToString(), label7);

            //SetText("簽發(fā)時(shí)間：" ExpireStart.ToString(), label8);

            //SetText("有效截止時(shí)間：" ExpireEnd.ToString(), label9);

            SetImage("photo.bmp", pictureBox1);

            CloseComm();

        }

2、  聲明一個(gè)客戶端調(diào)用的方法Test（這里沒(méi)有直接用數(shù)組）

        public string Test()

        {

            string str = "";

            foreach (string s in arrys)

            {

                str  = s   ",";

            }

            str = str.TrimEnd(',');

            return str;

}

三、將這個(gè)控件封裝成activex組件

在ReadCard類(lèi)的頭部添加

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

若要實(shí)現(xiàn)客戶端訪問(wèn)服務(wù)器端數(shù)據(jù)，則必須實(shí)現(xiàn)IObjectSafe接口

接口聲明如下：

    [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);

}

 四、新建一個(gè)web應(yīng)用程序項(xiàng)目

1、界面：

                <table style="width:100%;" border="1" width="100%" bordercolordark="#FFFFFF" cellspacing="0" cellpadding="2"bordercolor="#000000">

            <tr>

                <td style="width:33.3%; text-align: right;">證件號(hào)碼：</td>

                <td style="width:33.3%" id="td1">&nbsp;</td>

                <td style="width:33.3%; text-align: left;" rowspan="6">

                         <object id="csharpActiveX" name="csharpActiveX" classid="clsid:B9BB196C-5008-4156-840F-9FE37BA81502"></object></td>

            </tr>
