This example uses the Membership class to call the SqlMembershipProvider specified as the defaultProvider in the Web.config file. If you need to access the default provider as the type SqlMembershipProvider, you can cast the Provider property of the Membership class. To access other configured providers as a specific provider type, you can access them by their configured name with the Providers property of the Membership class and cast them as the specific provider type.

The maximum length for the UserName property is 256 characters. The maximum length for the Email property is 256 characters.

The password for a membership user cannot be updated using the UpdateUser method. To update the password for a membership user, use the ChangePassword method of the MembershipUser class.
