如何在C＃中从SmartCard读取凭据

using System;
using PCSC;

public static class SmartCardReader
{
    public static string ReadCredentialsFromSmartCard()
    {
        // 创建一个新的智能卡上下文
        using var context = new SCardContext();
        context.Establish();

        // 获取可用的读卡器列表
        var readerNames = context.GetReaders();

        // 如果没有可用的读卡器，则返回空字符串
        if (readerNames.Length == 0)
        {
            return string.Empty;
        }

        // 使用第一个可用的读卡器
        var readerName = readerNames[0];

        // 尝试连接到读卡器
        using var reader = new SCardReader(context);
        var connectResult = reader.Connect(readerName, SCardShareMode.Shared, SCardProtocol.T0 | SCardProtocol.T1);
        if (connectResult != SCardError.Success)
        {
            return string.Empty;
        }

        // 发送APDU命令以读取凭据
        var apduCommand = new byte[] { 0x00, 0xA4, 0x00, 0x00, 0x02, 0x31, 0x32, 0x33, 0x00 };
        var receivePci = new SCardPCI();
        var sendPci = new SCardPCI();
        var data = new byte[] { };
        var commandResult = reader.Transmit(apduCommand, ref sendPci, ref data, ref receivePci);

        // 如果命令执行成功，则返回读取到的凭据
        if (commandResult == SCardError.Success)
        {
            return BitConverter.ToString(data);
        }

        // 如果发生错误，则返回空字符串
        return string.Empty;
    }
}

var credentials = SmartCardReader.ReadCredentialsFromSmartCard();
Console.WriteLine($"Credentials: {credentials}");
