Precaución

La seguridad de acceso al código (CAS) ha quedado en desuso en todas las versiones de .NET Framework y .NET. Las versiones recientes de .NET no respetan las anotaciones cas y producen errores si se usan api relacionadas con CAS. Los desarrolladores deben buscar medios alternativos para realizar tareas de seguridad.

Puede usar PermissionSet para realizar operaciones en varios permisos diferentes como grupo.

Constructores

PermissionSet(PermissionSet)	Inicializa una nueva instancia de la clase PermissionSet con valores iniciales tomados del parámetro `permSet`.
PermissionSet(PermissionState)	Inicializa una nueva instancia de la clase PermissionSet con el objeto PermissionState especificado.

Propiedades

Count	Obtiene el número de objetos de permiso contenidos en el conjunto de permisos.
IsReadOnly	Obtiene un valor que indica si la colección es de solo lectura.
IsSynchronized	Obtiene un valor que indica si está garantizado que la colección es segura para la ejecución de subprocesos.
SyncRoot	Obtiene el objeto raíz de la colección actual.

Métodos

AddPermission(IPermission)	Agrega un permiso especificado a PermissionSet.
AddPermissionImpl(IPermission)	Agrega un permiso especificado a PermissionSet.
Assert()	Declara que el código de llamada puede tener acceso al recurso protegido por una demanda de permiso a través del código que llama a este método, incluso si los autores de la llamada situados en una posición más alta de la pila no tienen permiso para tener acceso al recurso. Con Assert() puede crear vulnerabilidades de seguridad.
ContainsNonCodeAccessPermissions()	Obtiene un valor que indica si PermissionSet contiene permisos que no se derivan de CodeAccessPermission.
ConvertPermissionSet(String, Byte[], String)	Obsoleto. Obsoleto. Convierte un PermissionSet codificado de un formato de codificación XML a otro formato de codificación XML.
Copy()	Crea una copia de la clase PermissionSet.
CopyTo(Array, Int32)	Copia los objetos de permiso del conjunto en la ubicación indicada de un Array.
Demand()	Fuerza una SecurityException en tiempo de ejecución si a todos los llamadores situados más arriba en la pila de llamadas no se les han concedido los permisos especificados por la instancia actual.
Deny()	Obsoleto. Obsoleto. Hace que cualquier Demand() que pase por el código de llamada para un permiso que tiene una intersección con un permiso de un tipo incluido en el PermissionSet actual genere un error.
Equals(Object)	Determina si el objeto PermissionSet o NamedPermissionSet especificado es igual al objeto PermissionSet actual.
Equals(Object)	Determina si el objeto especificado es igual que el objeto actual. (Heredado de Object)
FromXml(SecurityElement)	Reconstruye un objeto de seguridad con un estado especificado a partir de codificación XML.
GetEnumerator()	Devuelve un enumerador para los permisos del conjunto.
GetEnumeratorImpl()	Devuelve un enumerador para los permisos del conjunto.
