Exemplos

Esta seção fornece dois exemplos de código. O primeiro demonstra como especificar valores declarativamente para várias propriedades da TrustSection classe. O segundo demonstra como usar o TrustSection tipo.

O exemplo de arquivo de configuração a seguir mostra como especificar valores declarativamente para várias propriedades da TrustSection classe.

<system.web>
  <trust level="Full" originUrl=""/>
</system.web>

O exemplo de código a seguir demonstra como usar o TrustSection tipo.
