A System.Web.Security.MembershipUserCollection is returned from the GetAllUsers, FindUsersByName, and FindUsersByEmail methods of the System.Web.Security.Membership class. The MembershipUserCollection objects returned by the GetAllUsers, FindUsersByName, and FindUsersByEmail methods contain a snapshot of user information in the membership data store. That is, changes to the membership user information in a MembershipUserCollection are not reflected in the membership data store. To modify membership user information in the membership data store, use the UpdateUser, CreateUser and DeleteUser methods of the System.Web.Security.Membership class.
