C#-使用PCSC-Sharp写入智能卡 [英] C# - Write in Smartcard using PCSC-Sharp
问题描述
大家好，我想问一下如何用Smartcard编写.我仅依靠文档中给出的示例，但是它仅具有read标记. 我按照 https://github中的示例进行操作.com/danm-de/pcsc-sharp/blob/master/Examples/Transmit/Program.cs
using System;
using PCSC;
using PCSC.Iso7816;
namespace Transmit
{
public class Program
{
public static void Main() {
using (var context = new SCardContext()) {
context.Establish(SCardScope.System);
var readerNames = context.GetReaders();
if (readerNames == null || readerNames.Length < 1) {
Console.WriteLine("You need at least one reader in order to run this example.");
Console.ReadKey();
return;
}
var readerName = ChooseRfidReader(readerNames);
if (readerName == null) {
return;
}
using (var rfidReader = new SCardReader(context)) {
var sc = rfidReader.Connect(readerName, SCardShareMode.Shared, SCardProtocol.Any);
if (sc != SCardError.Success) {
Console.WriteLine("Could not connect to reader {0}:\n{1}",
readerName,
SCardHelper.StringifyError(sc));
Console.ReadKey();
return;
}
var apdu = new CommandApdu(IsoCase.Case2Short, rfidReader.ActiveProtocol) {
CLA = 0xFF,
Instruction = InstructionCode.GetData,
P1 = 0x00,
P2 = 0x00,
Le = 0 // We don't know the ID tag size
};
sc = rfidReader.BeginTransaction();
if (sc != SCardError.Success) {
Console.WriteLine("Could not begin transaction.");
Console.ReadKey();
return;
}
Console.WriteLine("Retrieving the UID .... ");
var receivePci = new SCardPCI(); // IO returned protocol control information.
var sendPci = SCardPCI.GetPci(rfidReader.ActiveProtocol);
var receiveBuffer = new byte[256];
var command = apdu.ToArray();
sc = rfidReader.Transmit(
sendPci, // Protocol Control Information (T0, T1 or Raw)
command, // command APDU
receivePci, // returning Protocol Control Information
ref receiveBuffer); // data buffer
if (sc != SCardError.Success) {
Console.WriteLine("Error: " + SCardHelper.StringifyError(sc));
}
var responseApdu = new ResponseApdu(receiveBuffer, IsoCase.Case2Short, rfidReader.ActiveProtocol);
Console.Write("SW1: {0:X2}, SW2: {1:X2}\nUid: {2}",
responseApdu.SW1,
responseApdu.SW2,
responseApdu.HasData ? BitConverter.ToString(responseApdu.GetData()) : "No uid received");
rfidReader.EndTransaction(SCardReaderDisposition.Leave);
rfidReader.Disconnect(SCardReaderDisposition.Reset);
Console.ReadKey();
}
}
}
private static string ChooseRfidReader(string[] readerNames) {
// Show available readers.
Console.WriteLine("Available readers: ");
for (var i = 0; i < readerNames.Length; i++) {
Console.WriteLine("[" + i + "] " + readerNames[i]);
}
// Ask the user which one to choose.
Console.Write("Which reader is an RFID reader? ");
var line = Console.ReadLine();
int choice;
if (!(int.TryParse(line, out choice)) || (choice < 0) || (choice > readerNames.Length)) {
Console.WriteLine("An invalid number has been entered.");
Console.ReadKey();
return null;
}
return readerNames[choice];
}
}
}
我阅读了文档，但无法完全理解如何使用CommandAdpu编写数据.如果有人可以向我提供有关如何编写智能卡的代码段，我将不胜感激.非常感谢你！

在开始任何操作之前，您应该先阅读有关Mifare卡的信息，可以获取文档 pyApduTool 来向卡片发送命令.
如果您有SCM阅读器，则此并搜索其他Mifare了解有关Mifare卡的主题.通过所有这些链接，您将知道写/读Mifare卡需要发送哪些命令，并且一旦知道要触发的APDU/命令，就可以在代码中构建与您已经说过用代码读取mifare相同的代码. .只需替换代码中的write命令，如果一切正常，就可以在您寻找的时候编写代码.
希望有帮助.
Good day everyone, I would like to ask on how to write in Smartcard. I just rely on the example given on the documentation but it only has read tag. I follow the examples here in https://github.com/danm-de/pcsc-sharp/blob/master/Examples/Transmit/Program.cs
using System;
using PCSC;
using PCSC.Iso7816;
namespace Transmit
{
public class Program

public static void Main() {
using (var context = new SCardContext()) {
context.Establish(SCardScope.System);
var readerNames = context.GetReaders();
if (readerNames == null || readerNames.Length < 1) {
Console.WriteLine("You need at least one reader in order to run this example.");
Console.ReadKey();
return;
}
var readerName = ChooseRfidReader(readerNames);
if (readerName == null) {
return;
}
using (var rfidReader = new SCardReader(context)) {
var sc = rfidReader.Connect(readerName, SCardShareMode.Shared, SCardProtocol.Any);
if (sc != SCardError.Success) {
Console.WriteLine("Could not connect to reader {0}:\n{1}",
readerName,
SCardHelper.StringifyError(sc));
Console.ReadKey();
return;
}
var apdu = new CommandApdu(IsoCase.Case2Short, rfidReader.ActiveProtocol) {
CLA = 0xFF,
Instruction = InstructionCode.GetData,
P1 = 0x00,
P2 = 0x00,
Le = 0 // We don't know the ID tag size
};
sc = rfidReader.BeginTransaction();
if (sc != SCardError.Success) {
Console.WriteLine("Could not begin transaction.");
Console.ReadKey();
return;
}
Console.WriteLine("Retrieving the UID .... ");
var receivePci = new SCardPCI(); // IO returned protocol control information.
var sendPci = SCardPCI.GetPci(rfidReader.ActiveProtocol);
var receiveBuffer = new byte[256];
var command = apdu.ToArray();
sc = rfidReader.Transmit(
sendPci, // Protocol Control Information (T0, T1 or Raw)
command, // command APDU
receivePci, // returning Protocol Control Information
ref receiveBuffer); // data buffer
if (sc != SCardError.Success) {
Console.WriteLine("Error: " + SCardHelper.StringifyError(sc));
}
var responseApdu = new ResponseApdu(receiveBuffer, IsoCase.Case2Short, rfidReader.ActiveProtocol);
Console.Write("SW1: {0:X2}, SW2: {1:X2}\nUid: {2}",
responseApdu.SW1,
responseApdu.SW2,
responseApdu.HasData ? BitConverter.ToString(responseApdu.GetData()) : "No uid received");
rfidReader.EndTransaction(SCardReaderDisposition.Leave);
rfidReader.Disconnect(SCardReaderDisposition.Reset);
Console.ReadKey();
}
}
}
private static string ChooseRfidReader(string[] readerNames) {
// Show available readers.
Console.WriteLine("Available readers: ");
for (var i = 0; i < readerNames.Length; i++) {
Console.WriteLine("[" + i + "] " + readerNames[i]);
}
// Ask the user which one to choose.
Console.Write("Which reader is an RFID reader? ");
var line = Console.ReadLine();
int choice;
if (!(int.TryParse(line, out choice)) || (choice < 0) || (choice > readerNames.Length)) {
Console.WriteLine("An invalid number has been entered.");
Console.ReadKey();
return null;
}
return readerNames[choice];
}
}
}
I read the documentation but I cannot fully understand on how to CommandAdpu of writing data. I will gladly appreciate if someone can provide me a code snippet on how to write in smart card. Thank you very much!

Before starting anything, You should read about Mifare card first, can get the document Here.
And then try to communicate with the card by any APDU tool.
You can use pyApduTool to send commands to the cards if you don't have any such tool.
If you have SCM reader then This document will help you to understand about commands need to send on Mifare classic card.
Also check this and search other Mifare topic to learn about Mifare cards. With all this links you will get to know what commands need to send to write/read Mifare cards and once you will know about APDU/Commands to fire, you can build the same in your code as you said you already read mifare with your code. Just replace write command in your code and if everything fine you can write as you looking for.
Hope it helps..
