Can User

Answer 1

Is your reason for this to save a database call everytime you need the UserId? If so, when I'm using the ASP.NET MembershipProvider, I usually either do a custom provider that allows me to cache that call, or a utility method that I can cache.

If you're thinking of putting it in the Profile, I don't see much reason for doing so, especially as it also will still require a database call and unless you are using a custom profile provider there, it has the added processing of parsing out the UserId.

If you're wondering why they did not implement a GetUserId method, it's simply because you're not always guaranteed that that user id will be a GUID as in the included provider.

EDIT:

See ScottGu's article on providers which provides a link to downloading the actual source code for i.e. SqlMembershipProvider.

But the simplest thing to do really is a GetUserId() method in your user object, or utility class, where you get the UserId from cache/session if there, otherwise hit the database, cache it by username (or store in session), and return it.
