C# .NET NET.pkcs11.dll在objToken.TokenInfo中引发异常system.formatexception

我使用以下代码访问令牌中的Certificate，模块获取关于令牌的信息

        Module module = Module.GetInstance(@"C:\WINDOWS\system32\eTPKCS11.dll");

        module.Initialize();

        Slot[] slots = module.GetSlotList(true);

        if (slots.Length== 0)
        {
            MessageBox.Show("No slot available");
            return null;
        }

        Token token = null;
        for (int i = 0; i < slots.Length; i++)
        {
            if (slots[i].SlotInfo.IsTokenPresent)
                token = slots[i].Token; // slots[i].token assigns token to Token object
        }

        token.TokenInfo;// throws exception at this line

        Session session = token.OpenSession(true);

        PIN pin = new PIN();
        pin.ShowDialog();

        // Executes the login passing the user PIN
        session.Login(UserType.USER,pin.Pin.ToCharArray());

        // Find RSA Private keys
        session.FindObjectsInit(new P11Attribute[]{new ObjectClassAttribute(CKO.PRIVATE_KEY),new KeyTypeAttribute(CKK.RSA)});  // hence when calling FindObjectInit method it throws ATTRIBUTE_VALUE_INVALID , stackTrace    at Net.Sf.Pkcs11.Wrapper.Pkcs11Module.checkCKR(CKR retVal)

Module Module=Module.GetInstance（@“C:\WINDOWS\system32\eTPKCS11.dll”）；
初始化（）模块；
Slot[]slots=module.GetSlotList（true）；

}

下面使用Cryptoki的代码用于获取256位RSA密钥 同样，我尝试使用Net.pkcs11.dll

公共字节[]解密（字节[]消息，字节[]键盘，字节[]模数） {

        Token token = null;
        for (int i = 0; i < slots.Count; i++)
        {
            if (slots[i].IsTokenPresent)
                token = slots[i].Token;
        }

        // Searchs for an RSA private key object
        // Sets the template with its attributes
        CryptokiCollection template_PrivateKey = new CryptokiCollection();
        template_PrivateKey.Add(new ObjectAttribute(ObjectAttribute.CKA_CLASS, CryptokiObject.CKO_PRIVATE_KEY));
        template_PrivateKey.Add(new ObjectAttribute(ObjectAttribute.CKA_KEY_TYPE, Key.CKK_RSA));

对于（int i=0；i

这一行是错的，你可以这样叫：

替换此行：

token.TokenInfo;// throws exception at this line

借

// Prints all information relating to the token
TokenInfo tinfo = token.Info;
Console.WriteLine(tinfo.Label);
Console.WriteLine(tinfo.ManufacturerID);
Console.WriteLine(tinfo.Model);
Console.WriteLine(tinfo.SerialNumber);
Console.WriteLine(tinfo.HardwareVersion);
