I hava just updated the wiki page with the print out
This is a snippet that prints out the label of the found keys:
// Launches the search specifying the template just created
CryptokiCollection pubKeyObjects = session.Objects.Find(templatePub , 100);
// prints the label of all keys
for(int i = 0; i < pubKeyObjects .count(); i++)
{
RSAPublicKey publicKey = (RSAPublicKey )pubKeyObjects[i];
Console.WriteLine("Public Key: " + publicKey.Label);
}
