Parâmetros

domainPolicy
PolicyLevel

O nível de política de segurança.The security policy level.

Atributos

Exceções

domainPolicy é null.domainPolicy is null.

O nível de política de segurança já foi definido.The security policy level has already been set.

A operação é tentada em um domínio de aplicativo descarregado.The operation is attempted on an unloaded application domain.

Exemplos

O exemplo a seguir demonstra como usar o método SetAppDomainPolicy para definir o nível de política de segurança de um domínio de aplicativo.The following example demonstrates how to use the SetAppDomainPolicy method to set the security policy level of an application domain.

using namespace System;
using namespace System::Threading;
using namespace System::Security;
using namespace System::Security::Policy;
using namespace System::Security::Permissions;
int main()
{
   
   // 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 );
   }

   AppDomain::Unload( domain );

Comentários

Chame esse método antes que um assembly seja carregado no AppDomain para que a política de segurança tenha efeito.Call this method before an assembly is loaded into the AppDomain in order for the security policy to have effect.
