Asp. NET program read the second generation ID card

Generally speaking, the WinForm application solves this problem easily, the Web application is a bit of a hassle.

Here I'm talking about my idea of a solution:

One, you need to have a joint model identity card reader (with drive CD), here I use the iDR200 electronics company, and have the development interface of this reader description.

Second, create a new WinForm control project Readcardcontrol, add a main class Readcard

1. Declaring DLL entry

[DllImport ("Sdtapi.dll")]
private static extern int Initcomm (int iport);//Initialize
[Dllimpor 　　　　　　　　 T ("Sdtapi.dll")]
private static extern int authenticate ();//card Authentication
[DllImport ("Sdtapi.dll")]
private static extern int Readbaseinfos (StringBuilder Name, StringBuilder Gender, StringBuilder Folk, Stringbuilde R Birthday, StringBuilder Code, StringBuilder address, StringBuilder Agency, StringBuilder expirestart, StringBuilder Ex 　　　　　　　　 Pireend);//Read data, recommended use
[DllImport ("Sdtapi.dll")]
private static extern int Closecomm ();//Close Port
[DllImport ("Sdtapi.dll")]
private static extern int readbasemsg (byte[] PMSG, ref int len);//read data, not here
[DllImport ("Sdtapi . dll ')]
private static extern int READBASEMSGW (byte[] PMSG, ref int len);//read data, not here
[dllimport ("Kernel32.dll")]
private static extern int Beep (int dwfreq, int dwduration);/To Roar

2. Card Reader method

private string[] Arrys = null;//declares an array to hold the identity card information


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 = {' i '};


byte[] pMsg = new byte[256];


string[] Baseinfo = new STRING[9];





//Open port


int intopenret = Initcomm (1001);


if (intopenret!= 1)


　　　　　　　　　　　　 {


//settext ("Reading equipment Not Connected", lblmsg);


return;


　　　　　　　　　　　　 }


//Card certification


int intreadret = authenticate ();


if (intreadret!= 1)


　　　　　　　　　　　　 {


//settext ("Card authentication failed", lblmsg);


Closecomm ();


return;


　　　　　　　　　　　　 }


//readbaseinfos (recommended)


int intreadbaseinfosret = Readbaseinfos (Name, Gender, Folk, Birthday, Code, address, Agency, Expiresta RT, Expireend);


if (Intreadbaseinfosret!= 1)


　　　　　　　　　　　　 {


//settext ("Read card failure", 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 ("Read card Success", lblmsg);


//settext ("certificate number:" + code.tostring (), Label1);


//settext ("Name:" + name.tostring (), Label2);


//settext ("Sex:" + gender.tostring (), label3);


//settext ("ethnic:" + folk.tostring (), label4);


//settext ("Date of birth:" + birthday.tostring (), Label5);


//settext ("Address:" + address.tostring (), label6);


//settext ("issuing authority:" + agency.tostring (), LABEL7);


//settext ("Issuing time:" + expirestart.tostring (), Label8);


//settext ("Effective cut-off time:" + expireend.tostring (), LABEL9);


setimage ("Photo.bmp", pictureBox1);


Closecomm ();
