Share the. Net program to read the second-generation ID Card (with source code)

Generally, the winform application is easy to solve this problem, and the Web application is a little more troublesome.

Here I will talk about my solution:

1. You need to have a resident ID card reader (with drive disc) for the connected model. Here I use the idr200 of jinglun Electronics Company and provide the development interface description for this reader.

2. Create a winform Control Project readcardcontrol and add a primary class readcard

1. Declare the DLL entry

[Dllimport ("sdtapi. dll")]

Private Static extern int initcomm (INT iport); // Initialization

[Dllimport ("sdtapi. dll")]

Private Static extern int authenticate (); // card authentication

[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 interval); // read data, recommended

[Dllimport ("sdtapi. dll")]

Private Static extern int closecomm (); // close the port

[Dllimport ("sdtapi. dll")]

Private Static extern int readbasemsg (byte [] PMSG, ref int Len); // read data, not required here

[Dllimport ("sdtapi. dll")]

Private Static extern int readbasemsgw (byte [] PMSG, ref int Len); // read data, not needed here

[Dllimport ("kernel32.dll")]

Private Static extern int BEEP (INT dwfreq, int dwduration); // used to scream

2. card reading Method

Private string [] arrys = NULL; // The array used to save the ID 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 = {'\ 0 '};

Byte [] PMSG = new byte [1, 256];

String [] baseinfo = new string [9];

 

// Open the port

Int bytes penret = initcomm (1001 );

If (else penret! = 1)

{

// Settext ("the reading machine is not connected", lblmsg );

Return;

}

// Card authentication

Int intreadret = authenticate ();

If (intreadret! = 1)

{

// Settext ("failed card authentication", lblmsg );

Closecomm ();

Return;

}

// Readbaseinfos (recommended)

Int intreadbaseinfosret = readbaseinfos (name, gender, folk, birthday, code, address, agency, expirestart, expireend );

If (intreadbaseinfosret! = 1)

{

// Settext ("failed to read the card", 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 ("card reading succeeded", lblmsg );

// Settext ("document number:" + code. tostring (), label1 );

// Settext ("name:" + name. tostring (), label2 );

// Settext ("Gender:" + gender. tostring (), label3 );

// Settext ("Nationality:" + folk. tostring (), label4 );

// Settext ("Date of Birth:" + birthday. tostring (), label5 );

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

// Settext ("Issuing Authority:" + agency. tostring (), label7 );

// Settext ("issue time:" + expirestart. tostring (), label8 );

// Settext ("effective end time:" + expireend. tostring (), label9 );

Setimage ("photo.bmp", picturebox1 );

Closecomm ();

}

2. Declare the method test called by a client (arrays are not directly used here)

Public String test ()

{

String STR = "";

Foreach (string s in arrys)

{

STR + = S + ",";

}

STR = Str. trimend (',');

Return STR;

}

3. encapsulate the control into an ActiveX component

Add the header in the readcard class

[GUID ("B9BB196C-5008-4156-840F-9FE37BA81502")]

To access server data from a client, you must implement the iobjectsafe interface.

The interface declaration is as follows:

[Comimport, guidattribute ("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]

[Interfacetypeattribute (cominterfacetype. interfaceisiunknown)]

Public interface iobjectsafe

{

[Preservesig]

Void getinterfacesafeoptions (ref guid ID, [financialas (unmanagedtype. U4)] ref int pdwsupportedoptions, [financialas (unmanagedtype. U4)] ref int pdwenabledoptions );

 

[Preservesig ()]

Void setinterfacesafeoptions (ref guid ID, [financialas (unmanagedtype. U4)] int dwoptionsetmask, [externalas (unmanagedtype. U4)] int dwenabledoptions );

}

4. Create a web application project

1. interface:

<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;"> credential number: </TD>

<TD style = "width: 33.3%" id = "TD1"> & nbsp; </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"> name: </TD>

<TD id = "td2"> & nbsp; </TD>

</Tr>

<Tr>

<TD style = "text-align: Right"> Gender: </TD>

<TD id = "td3"> & nbsp; </TD>

</Tr>

<Tr>

<TD style = "text-align: Right"> Nationality: </TD>

<TD id = "td4"> & nbsp; </TD>

</Tr>

<Tr>

<TD style = "text-align: Right"> Date of Birth: </TD>

<TD id = "td5"> & nbsp; </TD>

</Tr>

<Tr>

<TD style = "text-align: Right"> address: </TD>

<TD id = "td6"> & nbsp; </TD>

</Tr>

<Tr>

<TD style = "text-align: Right"> issuing authority: </TD>

<TD id = "td7"> & nbsp; </TD>

<TD> & nbsp; </TD>

</Tr>

<Tr>

<TD style = "text-align: Right"> Issue Date: </TD>

<TD id = "td8"> & nbsp; </TD>

<TD> & nbsp; </TD>

</Tr>

<Tr>

<TD style = "text-align: Right"> validity deadline: </TD>

<TD id = "td9"> & nbsp; </TD>

<TD> & nbsp; </TD>

</Tr>

 

</Table>

 

2. JavaScript code:

Function demo (){

Try {

VaR x = Document. getelementbyid ("csharpactivex ");

X. ontimer (); // read the image

VaR v = x. Test (); // read other ID card information

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); // you can specify to read data every 1 second.
