一般來說winform應用程序解決這個問題起來時很容易的,web應用程序就麻煩一點了。
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(帶驅動光盤),這裡我用的是精倫電子公司的 iDR200,並有這個閱讀器的開發接口說明。
二、新建一個winform控件項目ReadCardControl,添加一個主類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);//讀取數據,推薦使用
[DllImport("Sdtapi.dll")]
private static extern int CloseComm();//關閉端口
[DllImport("Sdtapi.dll")]
private static extern int ReadBaseMsg(byte[] pMsg, ref int len);//讀取數據,這裡不用
[DllImport("Sdtapi.dll")]
private static extern int ReadBaseMsgW(byte[] pMsg, ref int len);//讀取數據,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;//聲明用來保存身份證信息的數組
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];
//打開端口
int intOpenRet = InitComm(1001);
if (intOpenRet != 1)
{
//SetText("閱讀機具未連接", 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();
}
