Hi again,

I checked the problem more thoroughly and I found that
IsAssignableFrom also matches 'interfaces'. This can miss identify
other data types. Therefore my solution wasn't correct.

This one I guess is the correct one:

if (t == typeof(XmlRpcStruct) || t.IsSubclassOf(typeof(XmlRpcStruct)))

I tested it with some XmlRpcStruct child classes and it seems to work.

Best regards,
Javier Gonel.
