【问题描述】：

我需要读取文件身份的智能卡。

我在 ASP.NET 中使用带有执行方法的 winscard.dll：

SCardConnect() 

此函数返回以下错误：

retCode = -2146434970

不支持此代码。

查看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;

【问题讨论】：

您建议使用哪种语言标签？我查看了常见问题解答 (meta.stackexchange.com/questions/184108/…)，找不到任何适用于 ASP.NET 的内容。

【参考方案1】：

我建议将错误代码整数（C# 偶然？）转换为无符号数。它们的使用范围更广，可搜索性也更好。

PCSC-lite 文档声明代码0x80100066 表示卡无响应。这似乎适合您的问题，因此想法是，先尝试另一张卡，然后换读卡器。

更新：后来我注意到，您的错误代码列表对于某些代码似乎有所不同，因为它为 unreponsive card 列出了不同的编号，分析差异也可能会有所帮助。
