>But, as you can see, when this is a Binary type, I do not get something like 0xB3C54EFB6C02017046905007293650B1. There is already a ToString at the top which works ok for an Integer as I do not have to do additional processing. But, for a Binary type, ToString would simply show the type. How can I obtain the 0xB3C54EFB6C02017046905007293650B1 here?
