无法使用winscard.dll连接SmartCard？

Question

我需要阅读一份文件识别智能卡。

我在ASP.NET中使用winscard.dll和execute方法：

SCardConnect() 

此函数返回以下错误：

retCode = -2146434970

不支持此代码。

请参阅最后支持的错误列表。

方法ConnectCard和发送前的参数值：

hContext = -855572480
readername = "ACS ACR1281 1S Dual Reader ICC 0"
Card.SCARD_SHARE_SHARED = 2
Card.SCARD_PROTOCOL_T0 = 1
Card.SCARD_PROTOCOL_T1 = 2
hCard = 0
Protocol = 0



public bool connectCard()
    {
        connActive = true;
        retCode = Card.SCardConnect(hContext, readername, Card.SCARD_SHARE_SHARED,
                  Card.SCARD_PROTOCOL_T0 | Card.SCARD_PROTOCOL_T1, ref hCard, ref Protocol);

        if (retCode != Card.SCARD_S_SUCCESS)
        {

            MessageBox.Show(Card.GetScardErrMsg(retCode), "Card not available", MessageBoxButtons.OK, MessageBoxIcon.Error);
            connActive = false;
            return false;
        }
        return true;
    }

Answer 1

我建议将错误代码整数（C＃偶然？）转换为无符号数。这些更广泛使用，更好的可搜索。

PCSC-lite文档声明代码0x80100066表示卡无响应。这似乎适合你的问题，因此想法是，首先尝试另一张卡，然后交换阅读器。

更新：之后我注意到，您的错误代码列表对于某些代码似乎有所不同，因为它列出了不响应卡的不同数字，分析差异也可能有所帮助。
