Esempio

Nel codice seguente viene illustrato l'uso del Resolve metodo . Questo esempio di codice fa parte di un esempio più ampio fornito per la PolicyLevel classe .

// Demonstrate the use of ResolvePolicy for the supplied evidence and a specified policy level.
void CheckEvidence( PolicyLevel^ pLevel, Evidence^ evidence )
{
   // Display the code groups to which the evidence belongs.
   Console::WriteLine( "\tResolvePolicy for the given evidence: " );
   IEnumerator^ codeGroup = evidence->GetEnumerator();
   while ( codeGroup->MoveNext() )
   {
      Console::WriteLine( "\t\t{0}", (dynamic_cast<CodeGroup^>(codeGroup->Current))->Name );
   }

   Console::WriteLine( "The current evidence belongs to the following root CodeGroup:" );

   // pLevel is the current PolicyLevel, evidence is the Evidence to be resolved.
   CodeGroup^ cg1 = pLevel->ResolveMatchingCodeGroups( evidence );
   Console::WriteLine( "{0} Level", pLevel->Label );
   Console::WriteLine( "\tRoot CodeGroup = {0}", cg1->Name );

   // Show how Resolve is used to determine the set of permissions that 
   // the security system grants to code, based on the evidence.
   // Show the granted permissions. 
   Console::WriteLine( "\nCurrent permissions granted:" );
   PolicyStatement^ pState = pLevel->Resolve( evidence );
   Console::WriteLine( pState->ToXml() );
   return;
}

// Demonstrate the use of ResolvePolicy for the supplied evidence and a specified policy level.
private static void CheckEvidence(PolicyLevel pLevel, Evidence evidence)
{
    // Display the code groups to which the evidence belongs.
    Console.WriteLine("\tResolvePolicy for the given evidence: ");
    IEnumerator codeGroup = evidence.GetEnumerator();
    while (codeGroup.MoveNext())
    {
        Console.WriteLine("\t\t" + ((CodeGroup)codeGroup.Current).Name);
    }
    Console.WriteLine("The current evidence belongs to the following root CodeGroup:");
    // pLevel is the current PolicyLevel, evidence is the Evidence to be resolved.
    CodeGroup cg1 = pLevel.ResolveMatchingCodeGroups(evidence);
    Console.WriteLine(pLevel.Label + " Level");
    Console.WriteLine("\tRoot CodeGroup = " + cg1.Name);

    // Show how Resolve is used to determine the set of permissions that 
    // the security system grants to code, based on the evidence.

    // Show the granted permissions. 
    Console.WriteLine("\nCurrent permissions granted:");
    PolicyStatement pState = pLevel.Resolve(evidence);
    Console.WriteLine(pState.ToXml().ToString());

Commenti

Resolve è l'operazione di valutazione dei criteri di base per i livelli di criteri. Dato un set di evidenze come input, questo metodo verifica le condizioni di appartenenza dei gruppi di codice a partire dalla radice e funziona come corrispondente. La combinazione di autorizzazioni risultanti dai gruppi di codice corrispondenti produce un PolicyStatement oggetto restituito.

Nella concessione delle autorizzazioni al codice, i criteri di sicurezza usano le istruzioni dei criteri risolte per tutti i livelli di criteri applicabili, insieme alla richiesta di codice per le autorizzazioni.
