我使用Visual Studio 2013(C#)使用来自智能卡的证书对文档进行数字签名.我无法识别当前插入读卡器的证书:(

Windows复制插入读卡器中的所有卡的证书,并将其保存在商店中.我想在读卡器中使用卡片.

我使用的代码是

public static byte[] Sign(Stream inData, string certSubject)
{

    // Access Personal (MY) certificate store of current user

    foreach (X509Certificate2 cert in my.Certificates)
    {
        if (cert.Subject.Contains(certSubject))
        {
            // We found it. 
            // Get its associated CSP and private key
            if (cert.HasPrivateKey) {
                csp = (RSACryptoServiceProvider)cert.PrivateKey;
                if (csp.CspKeyContainerInfo.HardwareDevice)
                    Console.WriteLine("hardware");                              
                    Console.WriteLine(cert.ToString());
            }
        }
    }
    if (csp == …
