How to get the list of user ID who have login in?

The Login has a Username property that you can access in the Authenticate
event. On other pages you can simply use User.Identity.Name.

Thanks,
Besides the the user just login, I also want to know all the usrs on line.
How can I get the list of all users on line?

Identify and log each user into a database as they start to
view the site, and log them out when their sessions time out.

There's Membership.GetNumberOfUsersOnline, but oddly enough there's no Membership.UsersOnline.
Unfortunately you'll have to break encapsulation and do a select against
the tables that are storing this information. Those will vary depending upon
the membership provider.

You could also do as Juan suggests and maintain this information yourself
in your own database. Personally, I'd opt for this approach.
