Well, Firebird doesn't have a Boolean data type. Various programming
interfaces provide classes that allow your pseudo-Booleans to be
interpreted and handled by your program as though they were Booleans. The
proper place to ask your question re the .NET implementation would be the
firebird-net-provider list.
