Determina se o PermissionSet atual é um subconjunto do PermissionSet especificado.

public:
 bool IsSubsetOf(System::Security::PermissionSet ^ target);

public:
 virtual bool IsSubsetOf(System::Security::PermissionSet ^ target);

public bool IsSubsetOf (System.Security.PermissionSet target);

public bool IsSubsetOf (System.Security.PermissionSet? target);

public virtual bool IsSubsetOf (System.Security.PermissionSet target);

member this.IsSubsetOf : System.Security.PermissionSet -> bool

abstract member IsSubsetOf : System.Security.PermissionSet -> bool
override this.IsSubsetOf : System.Security.PermissionSet -> bool

Public Function IsSubsetOf (target As PermissionSet) As Boolean

Public Overridable Function IsSubsetOf (target As PermissionSet) As Boolean

Parâmetros

target

PermissionSet

O conjunto de permissões a testar para a relação do subconjunto. Isso deve ser um PermissionSet ou NamedPermissionSet.

Retornos

Boolean

true se PermissionSet atual for um subconjunto do parâmetro target; caso contrário, false.

Exemplos

O exemplo de código a seguir mostra o uso do IsSubsetOf método. Este exemplo de código faz parte de um exemplo maior fornecido para a 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))

Comentários

Um PermissionSet é um subconjunto do destino PermissionSet se todas as demandas que têm êxito para o PermissionSet também tiver êxito para o destino. Ou seja, o destino contém pelo menos as permissões contidas no subconjunto.
