Exemplos

Este exemplo demonstra como especificar valores declarativamente para vários atributos da membership secção, que também podem ser acedidos como membros da MembershipSection classe.

O exemplo seguinte do ficheiro de configuração mostra como especificar valores declarativamente para a membership secção.

<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"
        description="Stores and retrieves membership data from
          the local Microsoft SQL Server database."
      />
    </providers>
  </membership>
</system.web>

O exemplo de código seguinte demonstra como usar a MembershipSection classe.
