Attenzione

AppDomain policy levels are obsolete and will be removed in a future release of the .NET Framework. See http://go.microsoft.com/fwlink/?LinkID=155570 for more information.

Attenzione

AppDomain policy levels are obsolete

Imposta il livello dei criteri di sicurezza per il dominio applicazione.

Parametri

domainPolicy

PolicyLevel

Livello dei criteri di sicurezza.

Implementazioni

SetAppDomainPolicy(PolicyLevel)

Attributi

ObsoleteAttribute SecurityCriticalAttribute

Eccezioni

ArgumentNullException

domainPolicy è null.

PolicyException

Il livello dei criteri di sicurezza è già stato impostato.

AppDomainUnloadedException

L'operazione viene tentata in un dominio dell'applicazione non caricato.

Esempio

Nell'esempio seguente viene illustrato come usare il SetAppDomainPolicy metodo per impostare il livello dei criteri di sicurezza di un dominio applicazione.

using namespace System;

using namespace System::Security;
using namespace System::Security::Policy;
using namespace System::Security::Permissions;

   // Create a new application domain.
   AppDomain^ domain = System::AppDomain::CreateDomain( "MyDomain" );
   
   // Create a new AppDomain PolicyLevel.
   PolicyLevel^ polLevel = PolicyLevel::CreateAppDomainLevel();
   
   // Create a new, empty permission set.
   PermissionSet^ permSet = gcnew PermissionSet( PermissionState::None );
   
   // Add permission to execute code to the permission set.
   permSet->AddPermission( gcnew SecurityPermission( SecurityPermissionFlag::Execution ) );
   
   // Give the policy level's root code group a new policy statement based
   // on the new permission set.
   polLevel->RootCodeGroup->PolicyStatement = gcnew PolicyStatement( permSet );
   
   // Give the new policy level to the application domain.
   domain->SetAppDomainPolicy( polLevel );
   
   // Try to execute the assembly.
   try
   {
      
      // This will throw a PolicyException if the executable tries to
      // access any resources like file I/O or tries to create a window.
      domain->ExecuteAssembly( "Assemblies\\MyWindowsExe.exe" );
   }
   catch ( PolicyException^ e ) 
   {
      Console::WriteLine( "PolicyException: {0}", e->Message );
   }

Commenti

Chiamare questo metodo prima che un assembly venga caricato nell'oggetto AppDomain affinché i criteri di sicurezza abbiano effetto.
