virtual void SetAppDomainPolicy(
	PolicyLevel^ domainPolicy
) sealed

Parameters

domainPolicy
Type: System.Security.Policy::PolicyLevel^

The security policy level.

Implements

_AppDomain::SetAppDomainPolicy(PolicyLevel^)

Exception Condition
ArgumentNullException

domainPolicy is null.

PolicyException

The security policy level has already been set.

AppDomainUnloadedException

The operation is attempted on an unloaded application domain.

Call this method before an assembly is loaded into the AppDomain in order for the security policy to have effect.

The following example demonstrates how to use the SetAppDomainPolicymethod to set the security policy level of an application domain.

C#
C++
VB
Copy 
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 );
}
