Get mifare card serial number with WinSCard librar

问题:

I am working on an application that required reading the mifare card serial number, the language I am working with is C#.

I am new to mifare reader programming, so I am sorry for asking dumb question. At first I would like to know if there is a different between Mifare UID and Mifare Serial number.

I have managed to get UID with the help of WinSCard library, but I cant figure it out how to get the card serial number which should be 10 digit numbers.

I do appreciate if you could point me to the right direction.

Thanks in advance for the help. Regards

C# signature of SCardTransmit method

[StructLayout(LayoutKind.Sequential)]
public struct SCARD_IO_REQUEST
{
   public int dwProtocol;
   public int cbPciLength;
}

[DllImport("winscard.dll")]
public static extern int SCardTransmit(int hCard, ref SCARD_IO_REQUEST pioSendRequest,    ref byte SendBuff, int SendBuffLen, ref SCARD_IO_REQUEST pioRecvRequest,
ref byte RecvBuff, ref int RecvBuffLen);

Code Example for read UID of mifare card

private SmartcardErrorCode GetUID(ref byte[] UID)
    {
        byte[] receivedUID = new byte[10];
        UnsafeNativeMethods.SCARD_IO_REQUEST request = new UnsafeNativeMethods.SCARD_IO_REQUEST();
        request.dwProtocol = 1; //SCARD_PROTOCOL_T1);
        request.cbPciLength =    System.Runtime.InteropServices.Marshal.SizeOf(typeof(UnsafeNativeMethods.SCARD_IO_REQUEST));
        byte[] sendBytes = new byte[] { 0xFF, 0xCA, 0x00, 0x00, 0x04 }; //get UID command      for Mifare cards

        int outBytes = receivedUID.Length;
        int status = SCardTransmit(_hCard, ref request, ref sendBytes[0], sendBytes.Length,  ref request, ref receivedUID[0], ref outBytes);

        UID = receivedUID.Take(8).ToArray(); 
        return status;
    }
