原文: ASP.NET程序读取二代身份证（附源码）

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：

<tr>

</tr>

<tr>

</tr>

<tr>

</tr>

<tr>

</tr>

<tr>

</tr>

<tr>

</tr>

<tr>

</tr>

<tr>

</tr>

<tr>

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