pkcs11interop Get error code from exception
I have two cards with different types of tokens. When calling GetTokenInfo() I get CKR_TOKEN_NOT_RECOGNIZED on some tokens. My question is, how do I retrieve this error code in a clean manner?
HResult just indicates General Error.
I could check for the exception in the Message string.
The RV parameter is not part of the Exception class, not sure which derivative class to use to get this.
Solution
I had forgotten to add a using Net.Pkcs11Interop.Common;
Now I am catching Pkcs11Exception and retrieving the error code through the RV parameter, and comparing it against PKCS#11 error code.
Hope this can help others.
