Poznámky

Tato třída se používá k zajištění, že volající jsou zaregistrovaní v globální mezipaměti sestavení (GAC).

Rozsah deklarace, který je povolen, závisí na použité hodnotě SecurityAction .

Informace o zabezpečení deklarované atributem zabezpečení jsou uloženy v metadatech cíle atributu a systém k tomu přistupuje za běhu. Atributy zabezpečení se používají pouze pro deklarativní zabezpečení. Pro imperativní zabezpečení použijte odpovídající třídu GacIdentityPermissionoprávnění .

Další informace o používání atributů najdete v tématu Atributy.
