Cuidado
Code Access Security is not supported or honored by the runtime.
Cuidado
CAS support is not available with Silverlight applications.
Especifica sinalizadores de acesso para o objeto de permissão de segurança.
Essa enumeração dá suporte a uma combinação bit a bit dos valores de membro.

Campos
| AllFlags | 16383 | O estado irrestrito da permissão. |
| Assertion | 1 | Capacidade de declarar que todos os chamadores desse código têm a permissão necessária para a operação. |
| BindingRedirects | 8192 | Permissão para executar o redirecionamento de associação explícita no arquivo de configuração de aplicativo. Isso inclui o redirecionamento dos assemblies do .NET que foram unificados, bem como outros assemblies localizados fora do .NET. |
| ControlAppDomain | 1024 | Capacidade de criar e manipular um AppDomain. |
| ControlDomainPolicy | 256 | Capacidade de especificar a política de domínio. |
| ControlEvidence | 32 | Capacidade de fornecer evidências, incluindo a capacidade de alterar a evidência fornecida pelo Common Language Runtime. Essa é uma permissão avançada que deve ser concedida apenas a código altamente confiável. |
| ControlPolicy | 64 | Capacidade de exibir e modificar a política. Essa é uma permissão avançada que deve ser concedida apenas a código altamente confiável. |
| ControlPrincipal | 512 | Capacidade de manipular o objeto de entidade de segurança. |
| ControlThread | 16 | Capacidade de usar determinadas operações avançadas em threads. |
| Execution | 8 | Permissão que o código seja executado. Sem essa permissão, o código gerenciado não será executado. Esse sinalizador não tem efeito quando usado de forma dinâmica com modificadores de pilha, como Deny(), Assert() e PermitOnly(). |
| Infrastructure | 4096 | Permissão para conectar o código à infraestrutura de Common Language Runtime, como a adição de Coletores de contexto de comunicação remota, coletores Envoy e coletores dinâmicos. |
| NoFlags | 0 | Sem acesso de segurança. |
| RemotingConfiguration | 2048 | Permissão para configurar canais e tipos de comunicação remota. |
| SerializationFormatter | 128 | Capacidade de fornecer serviços de serialização. Usado por formatadores de serialização. |
| SkipVerification | 4 | Capacidade de ignorar a verificação de código neste assembly. O código não verificável poderá ser executado se esta permissão for concedida. Essa é uma permissão avançada que deve ser concedida apenas a código altamente confiável. Esse sinalizador não tem efeito quando usado de forma dinâmica com modificadores de pilha, como Deny(), Assert() e PermitOnly(). |
| UnmanagedCode | 2 | Capacidade de chamar código não gerenciado. Uma vez que o código não gerenciado potencialmente permite que outras permissões sejam ignoradas, essa é uma permissão perigosa que deve ser concedida apenas a código altamente confiável. Ela é usada para aplicativos como o código nativo de chamada usando invocação de plataforma ou interoperabilidade COM. |

Cuidado
O CAS (Segurança de Acesso do Código) foi preterido em todas as versões do .NET Framework e do .NET. As versões recentes do .NET não aceitam anotações de CAS e produzem erros caso as APIs relacionadas ao CAS sejam usadas. Os desenvolvedores devem buscar meios alternativos de realizar tarefas de segurança.
Essa enumeração é usada por SecurityPermission.
Cuidado
Muitos desses sinalizadores são poderosos e só devem ser concedidos a códigos altamente confiáveis.
