分享下.NET程式讀取二代身份證（附原始碼
一般來說winform應用程式解決這個問題起來時很容易的，web應用程式就麻煩一點了。
這裡我說說我的解決思路：
一、你必要有聯機型居民身份證閱讀器一個（帶驅動光碟），這裡我用的是精倫電子公司的iDR200,並有這個閱讀器的開發介面說明。
二、新建一個winform控制元件專案ReadCardControl，新增一個主類ReadCard
1、 宣告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);//讀取資料，推薦使用
[DllImport("Sdtapi.dll")]
private static extern int CloseComm();//關閉埠
[DllImport("Sdtapi.dll")]
private static extern int ReadBaseMsg(byte[] pMsg, ref int len);//讀取資料，這裡不用
[DllImport("Sdtapi.dll")]
private static extern int ReadBaseMsgW(byte[] pMsg, ref int len);//讀取資料，這裡不用
[DllImport("kernel32.dll")]
private static extern int Beep(int dwFreq, int dwDuration);//用來大吼一聲
2、讀卡方法
private string[] arrys = null;//宣告用來儲存身份證資訊的陣列
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];
//開啟埠
int intOpenRet = InitComm(1001);
if (intOpenRet != 1)
{
//SetText("閱讀機具未連線", lblMsg);
return;
}
//卡認證
int intReadRet = Authenticate();
if (intReadRet != 1)
{
//SetText("卡認證失敗", 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("簽發機關：" + Agency.ToString(), label7);
//SetText("簽發時間：" + ExpireStart.ToString(), label8);
//SetText("有效截止時間：" + ExpireEnd.ToString(), label9);
SetImage("photo.bmp", pictureBox1);
CloseComm();
}
2、 宣告一個客戶端呼叫的方法Test（這裡沒有直接用陣列）
public string Test()
{
string str = "";
foreach (string s in arrys)
{
str += s + ",";
}
str = str.TrimEnd(',');
return str;
}
三、將這個控制元件封裝成activex元件
在ReadCard類的頭部新增
[Guid("B9BB196C-5008-4156-840F-9FE37BA81502")]
若要實現客戶端訪問伺服器端資料，則必須實現IObjectSafe介面
介面宣告如下：
[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設計 /// <summary> /// 必需的設計器變數。 /// </summary> private System.ComponentModel.IContainer components = null;/// <summary> /// 清理所有正在使用的資源。 /// </summary> /// <param name="disposing">如果應釋放託管資源，為 true；否則為 false。</param> protected override void Dispose(bool disposing) { if (disposing && (components != null)) { components.Dispose(); } base.Dispose(disposing); }
#region 元件設計器生成的程式碼
/// <summary> /// 設計器支援所需的方法 - 不要 /// 使用程式碼編輯器修改此方法的內容。 /// </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、新建一個web應用程式專案
1、介面：
<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;">證件號碼：</td>
<td style="width:33.3%" id="td1"> </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"> </td>
</tr>
<tr>
<td style="text-align: right">性別：</td>
<td id="td3"> </td>
</tr>
<tr>
<td style="text-align: right">民族：</td>
<td id="td4"> </td>
</tr>
<tr>
<td style="text-align: right">出生日期：</td>
<td id="td5"> </td>
</tr>
<tr>
<td style="text-align: right">地址：</td>
<td id="td6"> </td>
</tr>
<tr>
<td style="text-align: right">簽發機關：</td>
<td id="td7"> </td>
<td> </td>
</tr>
<tr>
<td style="text-align: right">簽發時間：</td>
<td id="td8"> </td>
<td> </td>
</tr>
<tr>
<td style="text-align: right">有效截止時間：</td>
<td id="td9"> </td>
<td> </td>
</tr>
</table>
2、Javascript程式碼：
function Demo() {
try {
var x = document.getElementById("csharpActiveX");
x.OnTimer();//讀取圖片
var v = x.Test();//讀取身份證其他資訊
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);//設定每隔1秒鐘讀取一次
大功告成。。。下載原始碼
截個效果圖：
每天進步一點點...
