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 /// /// 必需的设计器变量。 /// private System.ComponentModel.IContainer components = null; /// /// 清理所有正在使用的资源。 /// ///如果应释放托管资源,为 true;否则为 false。 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 /// /// 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。 /// 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:

证件号码: 
姓名: 
性别: 
民族: 
出生日期: 
地址: 
签发机关:  
签发时间:  
有效截止时间:  

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
