Membership.GetUser retrieves the user information from the data source and creates a System.Web.Security.MembershipUser object populated with the returned data. If you use one of the Membership.GetUser overloads that does not take a username parameter, Membership.GetUser returns the information for the current logged-on membership user. The current logged-on membership user is identified by the System.Security.Principal.IIdentity.Name of the user in the current System.Web.HttpContext.

You can also specify whether you want Membership.GetUser to update the last-activity date/time stamp for the user being retrieved using the userIsOnline parameter. Of the erload:System.Web.Security.Membership.GetUser overloads that do not take a userIsOnline parameter, GetUser() implicitly updates the last-activity date/time stamp for the user. GetUser(System.String) and GetUser(System.Object) do not.
