Absolutely, a class can inherit from a single base class and implement any number of interfaces at the same time.

Your example does not work because the one base class must be listed first, before all the interfaces...

Yes, but you do it like this:

public partial class RegistrationForm : System.Web.UI.UserControl, IRegistrationForm

C# doesn't support multiple inheritance, so you put the class you inherit from first, followed by a comma, followed by a comma-delimited list of the interfaces it implements.
