Transition from Crypt2.GetSignerCertChain to Crypt2.LastSignerCert

Provides instructions for replacing deprecated GetSignerCertChain method calls with LastSignerCert. C#

bool success = false;

Chilkat.Crypt2 crypt2 = new Chilkat.Crypt2();

//  ...
//  ...
int index = 0;

//  ------------------------------------------------------------------------
//  The GetSignerCertChain method is deprecated:

Chilkat.CertChain certchainObj = crypt2.GetSignerCertChain(index);
if (crypt2.LastMethodSuccess == false) {
    Debug.WriteLine(crypt2.LastErrorText);
    return;
}

//  ...
//  ...

//  ------------------------------------------------------------------------
//  Do the equivalent using LastSignerCert, and then get the certificate chain from the cert.
//  Your application creates a new, empty Cert object which is passed 
//  in the last argument and filled upon success.

Chilkat.Cert signerCert = new Chilkat.Cert();
success = crypt2.LastSignerCert(index,signerCert);
if (success == false) {
    Debug.WriteLine(crypt2.LastErrorText);
    return;
}

Chilkat.CertChain certChain = new Chilkat.CertChain();
success = signerCert.BuildCertChain(certChain);
if (success == false) {
    Debug.WriteLine(signerCert.LastErrorText);
    return;
}
