請問各位先進：
如何將此C#的宣告，如何改為Delphi方式，在此先行謝謝

public struct SCARD_IO_REQUEST {
public int dwProtocol;
public int cbPciLength;
}

public static extern int SCardTransmit(int hCard,
ref SCARD_IO_REQUEST pioSendPci, byte[] pbSendBuffer, int cbSendLength,
ref SCARD_IO_REQUEST pioRecvPci, ref byte pbRecvBuffer, ref int pcbRecvLength);

HI, 可以這樣用

[code delphi]
SCARD_IO_REQUEST = record
dwProtocol: Integer;
cbPciLength: Integer;
end;

function SCardTransmit(hCard: Integer;
pioSendPci: SCARD_IO_REQUEST;
pbSendBuffer: array of byte;
pioRecvPci: SCARD_IO_REQUEST;
pbRecvBuffer: Byte;
pcbRecvLength: Integer): Integer; external;
[/code]

價值的展現，來自於你用哪一個角度來看待它!!

編輯記錄

照 WinScard.dll API   int 與 uint 值域是不一樣的
hCard 是 uint
應宣告這樣
public static extern int SCardTransmit(uint hCard,
public static extern int SCardTransmit(int hCard,

但是還是可以運作 hCard會變成負的







C# CODE FOR WinScard.dll
有空可以幫轉一下Delphi ? 這樣比較完整 當成Delphi 的Resource ~~
