Exemples

Cet exemple montre comment spécifier des valeurs déclarativement pour plusieurs attributs de la membership section, qui peuvent également être accessibles en tant que membres de la MembershipSection classe.

L’exemple de fichier de configuration suivant montre comment spécifier des valeurs déclarativement pour la membership section.

<system.web>  
  <membership   
    defaultProvider="AspNetSqlMembershipProvider"  
    userIsOnlineTimeWindow="15">  
    <providers>  
      <add   
        name=" AspNetSqlMembershipProvider"  
        type="System.Web.Security.SqlMembershipProvider, System.Web,   
          Version=2.0.3600.0, Culture=neutral,   
          PublicKeyToken=b03f5f7f11d50a3a"  
        connectionStringName="LocalSqlServer"  
        passwordAttemptThreshold="5"  
        passwordAttemptWindow="10"  
        enablePasswordRetrieval="false"  
        enablePasswordReset="true"  
        requiresQuestionAndAnswer="true"  
        applicationName="/"  
        requiresUniqueEmail="false"  
        passwordFormat="Hashed"

          the local Microsoft SQL Server database."  
      />  
    </providers>  
  </membership>
