Beispiele

Der folgende Code zeigt die Verwendung der Resolve Methode. Dieses Codebeispiel ist Teil eines größeren Beispiels, das für die PolicyLevel Klasse bereitgestellt wird.

// 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);
    }

    // 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:");

Hinweise

Resolve ist der grundlegende Richtlinienauswertungsvorgang für Richtlinienebenen. Angesichts einer Reihe von Nachweisen als Eingabe testet diese Methode die Mitgliedschaftsbedingungen von Codegruppen, die am Stamm beginnen und wie abgeglichen funktionieren. Die Kombination von Berechtigungen, die sich aus den übereinstimmenden Codegruppen ergeben, erzeugt ein PolicyStatement zurückgegebenes Ergebnis.

Bei der Gewährung von Berechtigungen für Code verwendet die Sicherheitsrichtlinie die aufgelösten Richtlinienanweisungen für alle anwendbaren Richtlinienebenen zusammen mit der Codeanforderung für Berechtigungen.
