Parametri

target
PermissionSet

Set di autorizzazioni da testare per la relazione di subset. Deve essere un oggetto PermissionSet o NamedPermissionSet.

Restituisce

Boolean

true se l'oggetto PermissionSet corrente è un subset del parametro target; in caso contrario, false.

Esempio

Nell'esempio di codice seguente viene illustrato l'uso IsSubsetOf del metodo. Questo esempio di codice fa parte di un esempio più grande fornito per la PermissionSet classe.

// Create a second permission set and compare it to the first permission set.
ps2->AddPermission( gcnew EnvironmentPermission( EnvironmentPermissionAccess::Read,"USERNAME" ) );
ps2->AddPermission( gcnew EnvironmentPermission( EnvironmentPermissionAccess::Write,"COMPUTERNAME" ) );
IEnumerator^ list =  ps1->GetEnumerator();
Console::WriteLine("Permissions in first permission set:");
      while (list->MoveNext())
          Console::WriteLine(list->Current->ToString());
Console::WriteLine( "Second permission IsSubsetOf first permission = {0}", ps2->IsSubsetOf( ps1 ) );

// Create a second permission set and compare it to the first permission set.
ps2.AddPermission(
    new EnvironmentPermission(EnvironmentPermissionAccess.Read, "USERNAME"));
ps2.AddPermission(
    new EnvironmentPermission(EnvironmentPermissionAccess.Write, "COMPUTERNAME"));
IEnumerator list =  ps1.GetEnumerator();
Console.WriteLine("Permissions in first permission set:");
while (list.MoveNext())
    Console.WriteLine(list.Current.ToString());
Console.WriteLine("Second permission IsSubsetOf first permission = " + ps2.IsSubsetOf(ps1));

' Create a second permission set and compare it to the first permission set.
ps2.AddPermission(New EnvironmentPermission(EnvironmentPermissionAccess.Read, "USERNAME"))
ps2.AddPermission(New EnvironmentPermission(EnvironmentPermissionAccess.Write, "COMPUTERNAME"))
Console.WriteLine("Permissions in first permission set:")
Dim list As IEnumerator = ps1.GetEnumerator()
While list.MoveNext()
    Console.WriteLine(list.Current.ToString())
End While
Console.WriteLine("Second permission IsSubsetOf first permission = " & ps2.IsSubsetOf(ps1))

Commenti

Un PermissionSet è un subset della destinazione PermissionSet se tutte le richieste che hanno esito positivo per la PermissionSet destinazione hanno esito positivo. Ovvero, la destinazione contiene almeno le autorizzazioni contenute nel subset.
