In diesem Beispiel wird veranschaulicht, wie Sie deklarativ für mehrere Attribute des membership-Abschnitts Werte angeben, auf die auch als Member der MembershipSection-Klasse zugegriffen werden kann.
Im folgenden Beispiel für eine Konfigurationsdatei wird veranschaulicht, wie Sie deklarativ Werte für den membership-Abschnitt angeben.
<system.web>
<membership
defaultProvider="AspNetSqlMembershipProvider"
userIsOnlineTimeWindow="15">
<providers>
<add
name=" AspNetSqlMembershipProvider"

passwordAttemptThreshold="5"
passwordAttemptWindow="10"
