Enumeração SecurityPermissionFlag

Especifica sinalizadores de acesso para o objeto de permissão de segurança.

Esta enumeração tem um atributo FlagsAttribute que permite uma combinação bit a bit de seus valores de membro.

Namespace:  System.Security.Permissions
Assembly:  mscorlib (em mscorlib.dll)

[SerializableAttribute]
[ComVisibleAttribute(true)]
[FlagsAttribute]
public enum SecurityPermissionFlag

Nome do membroDescrição
NoFlags Sem acesso de segurança.
Assertion Capacidade de declarar que chamadores de todo esse código têm a permissão necessária para a operação.
UnmanagedCode Capacidade de chamar código não gerenciado.

Uma vez que o código não gerenciado potencialmente permite outras permissões ser ignorada, isso é uma permissão perigosa que deve ser concedida somente a código altamente confiável.Ele é usado para aplicativos sistema autônomo chamar código nativo usando PInvoke ou usando a interoperabilidade COM.

SkipVerificationCapacidade de ignorar a verificação de código neste assembly.O código não verificado pode ser executado se essa permissão é concedida.

Esta é uma permissão poderosa que deve ser concedida somente ao código altamente confiável.

Este sinalizar não tem efeito quando usado com modificadores de pilha, sistema autônomo dinamicamenteDeny, Assert, e PermitOnly.

ExecutionPermissão para que o código seja executado.Sem essa permissão, código gerenciado não será executado.

Este sinalizar não tem efeito quando usado com modificadores de pilha, sistema autônomo dinamicamenteDeny, Assert, e PermitOnly.

ControlThread Capacidade de usar determinadas operações avançadas em threads.
ControlEvidence Capacidade de fornecer provas, incluindo a capacidade de alterar as evidência fornecida pelo Common linguagem tempo de execução.

Esta é uma permissão poderosa que deve ser concedida somente a código altamente confiável.

ControlPolicy Capacidade de exibir e modificar a diretiva.

Esta é uma permissão poderosa que deve ser concedida somente a código altamente confiável.

SerializationFormatterCapacidade de fornecer serviços de serialização.Usado por formatadores de serialização.
ControlDomainPolicy Capacidade de especificar a diretiva de domínio.
ControlPrincipal Capacidade de manipular o objeto entidade de segurança de segurança.
ControlAppDomain Capacidade de criar e manipular um AppDomain.
RemotingConfiguration Permissão para configurar tipos de comunicação remota e canais.
Infrastructure Permissão de conectar-se código em infra-o linguagem em tempo de execução estrutura comum, sistema autônomo a adição de Coletores de contexto de comunicação remota, Envoy Sinks e Sinks dinâmico.
BindingRedirectsPermissão para executar o redirecionamento de uma ligação explícita no arquivo de configuração do aplicativo.Isso inclui o redirecionamento de assemblies do .NET estrutura que tenham sido unificado, bem sistema autônomo outros assemblies encontrados fora do .NET estrutura.
AllFlags O estado da permissão irrestrito.

Essa enumeração possui um FlagsAttribute atributo que permite uma combinação de seus valores membro bit a bit.

Essa enumeração é usada por SecurityPermission.

Observação de cuidadoCuidado:

Muitos desses sinalizadores são eficientes e devem ser concedidos somente a código altamente confiável.

O exemplo de código a seguir mostra o uso do SecurityPermissionFlag enumeração para negar e exigem permissões de segurança.
