Exemplos

O código seguinte mostra a utilização do Resolve método. Este exemplo de código faz parte de um exemplo maior fornecido para a PolicyLevel classe.

// Demonstrate the use of ResolvePolicy for the supplied evidence and a specified policy level.

   // the security system grants to code, based on the evidence.

Observações

Resolve é a operação básica de avaliação de políticas para os níveis de política. Dado um conjunto de evidências como entrada, este método testa as condições de pertença de grupos de código que começam na raiz e descem conforme correspondido. A combinação de permissões resultante dos grupos de código correspondentes produz um PolicyStatement que é devolvido.

Ao conceder permissões para o código, a política de segurança utiliza as declarações de política resolvidas para todos os níveis de política aplicáveis, juntamente com o pedido de permissões do código.
