分享下.NET程序读取二代身份证(附源码 -

[日期:2013-04-12] 来源:  作者: [字体: ]

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);

}

 

UI设计
/// <summary>         /// 必需的设计器变量。         /// </summary>         private System.ComponentModel.IContainer components = null;
        /// <summary>         /// 清理所有正在使用的资源。         /// </summary>         /// <param name="disposing">如果应释放托管资源,为 true;否则为 false。</param>         protected override void Dispose(bool disposing)         {             if (disposing && (components != null))             {                 components.Dispose();             }             base.Dispose(disposing);         }
        #region 组件设计器生成的代码
        /// <summary>         /// 设计器支持所需的方法 - 不要         /// 使用代码编辑器修改此方法的内容。         /// </summary>         private void InitializeComponent()         {             this.pictureBox1 = new System.Windows.Forms.PictureBox();             ((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).BeginInit();             this.SuspendLayout();             //             // pictureBox1             //             this.pictureBox1.Location = new System.Drawing.Point(3, 3);             this.pictureBox1.Name = "pictureBox1";             this.pictureBox1.Size = new System.Drawing.Size(100, 130);             this.pictureBox1.TabIndex = 12;             this.pictureBox1.TabStop = false;             //             // ReadCard             //             this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 12F);             this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;             this.Controls.Add(this.pictureBox1);             this.Name = "ReadCard";             this.Size = new System.Drawing.Size(107, 135);             ((System.ComponentModel.ISupportInitialize)(this.pictureBox1)).EndInit();             this.ResumeLayout(false);
        }
        #endregion
        private System.Windows.Forms.PictureBox pictureBox1;

 

四、新建一个web应用程序项目

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;">证件号码:</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>

            <tr>

                <td style="text-align: right">姓名:</td>

                <td id="td2">&nbsp;</td>

            </tr>

            <tr>

                <td style="text-align: right">性别:</td>

                <td id="td3">&nbsp;</td>

            </tr>

            <tr>

                <td style="text-align: right">民族:</td>

                <td id="td4">&nbsp;</td>

            </tr>

            <tr>

                <td style="text-align: right">出生日期:</td>

                <td id="td5">&nbsp;</td>

            </tr>

            <tr>

                <td style="text-align: right">地址:</td>

                <td id="td6">&nbsp;</td>

            </tr>

            <tr>

                <td style="text-align: right">签发机关:</td>

                <td id="td7">&nbsp;</td>

                <td>&nbsp;</td>

            </tr>

            <tr>

                <td style="text-align: right">签发时间:</td>

                <td id="td8">&nbsp;</td>

                <td>&nbsp;</td>

            </tr>

            <tr>

                <td style="text-align: right">有效截止时间:</td>

                <td id="td9">&nbsp;</td>

                <td>&nbsp;</td>

            </tr>

 

        </table>

 

2、Javascript代码:

      function Demo() {

            try {

                var x = document.getElementById("csharpActiveX");

                x.OnTimer();//读取图片

                var v = x.Test();//读取身份证其他信息

                var arrys = v.split(',');

                if (arrys.length > 9) {

                    document.getElementById("td1").innerHTML = arrys[0];

                    document.getElementById("td2").innerHTML = arrys[1];

                    document.getElementById("td3").innerHTML = arrys[2];

                    document.getElementById("td4").innerHTML = arrys[3];

                    document.getElementById("td5").innerHTML = arrys[4];

                    document.getElementById("td6").innerHTML = arrys[5];

                    document.getElementById("td7").innerHTML = arrys[6];

                    document.getElementById("td8").innerHTML = arrys[7];

                    document.getElementById("td9").innerHTML = arrys[8];

                }

            }

            catch (e) {

                //alert(e.message)

            }

        }

        setInterval(Demo, 1000);//设置每隔1秒钟读取一次

大功告成。。。下载源码

每天进步一点点...
