HostProtectionResource Enumeração

Definição

Namespace:

System.Security.Permissions

Assembly:

System.Security.Permissions.dll

Assembly:

mscorlib.dll

Cuidado

Code Access Security is not supported or honored by the runtime.

Especifica as categorias de funcionalidade potencialmente prejudicial ao host quando invocado por uma classe ou um método.

Essa enumeração dá suporte a uma combinação bit a bit dos valores de membro.

None	0	Não expõe nenhum recurso de host.
SecurityInfrastructure	64	Expõe a infraestrutura de segurança.
SelfAffectingProcessMgmt	8	Pode sair do processo atual, encerrando o servidor.

Exemplos

O exemplo de código a seguir mostra o uso da HostProtectionResource enumeração com o HostProtectionAttribute atributo. Este exemplo faz parte de um exemplo maior fornecido para a HostProtectionAttribute classe.

// Use the enumeration flags to indicate that this method exposes shared state and 
// self-affecting process management.
// Either of the following attribute statements can be used to set the 
// resource flags.
// Exit the sample when an exception is thrown.

[HostProtection(SharedState=true,SelfAffectingProcessMgmt=true)]
[HostProtection(Resources=HostProtectionResource::SharedState|
HostProtectionResource::SelfAffectingProcessMgmt)]
static void Exit( String^ Message, int Code )
{
   Console::WriteLine( "\nFAILED: {0} {1}", Message, Code );
   Environment::ExitCode = Code;
   Environment::Exit( Code );
}

// Use the enumeration flags to indicate that this method exposes 
// shared state and self-affecting process management.
// Either of the following attribute statements can be used to set the
// resource flags.
[HostProtectionAttribute(SharedState = true, 
    SelfAffectingProcessMgmt = true)]
[HostProtectionAttribute(Resources = HostProtectionResource.SharedState |
     HostProtectionResource.SelfAffectingProcessMgmt)]
private static void Exit(string Message, int Code)
{
    // Exit the sample when an exception is thrown.
    Console.WriteLine("\nFAILED: " + Message + " " + Code.ToString());
    Environment.ExitCode = Code;
    Environment.Exit(Code);
}

' Use the enumeration flags to indicate that this method exposes 
' shared state and self-affecting process management.
' Either of the following attribute statements can be used to set the 
' resource flags.
<HostProtectionAttribute(SharedState := True, _
    SelfAffectingProcessMgmt := True), _
    HostProtectionAttribute( _
    Resources := HostProtectionResource.SharedState Or _
    HostProtectionResource.SelfAffectingProcessMgmt)> _
Private Shared Sub [Exit](ByVal Message As String, ByVal Code As Integer)

    ' Exit the sample when an exception is thrown.
    Console.WriteLine((ControlChars.Lf & "FAILED: " & Message & " " & _
        Code.ToString()))
    Environment.ExitCode = Code
    Environment.Exit(Code)
End Sub
