ReflectionPermission (Clase)

Controla el acceso a los metadatos a través de las API System.Reflection. No se puede heredar esta clase.

Type es la raíz de la funcionalidad System.Reflection. Sin ReflectionPermission, el código sólo puede tener acceso a los miembros public de los ensamblados cargados. Se incluye, entre otros, el acceso sin restricciones a Object.GetType, el acceso a los tipos public exportados a través de Type.GetType y el acceso a GetTypeFromHandle. Es posible obtener acceso a algunas propiedades de Type, como FullName y Attributes, sin ReflectionPermission.

El código con su pertinente ReflectionPermission tiene acceso a los miembros public, protected e incluso private de cualquier Type cargado. Aquí se incluye el acceso a Module, Assembly, BaseType y GetInterfaces.

Nota de precauciónPrecaución

Dado que ReflectionPermission puede proporcionar acceso a miembros de clase y metadatos privados, se recomienda no conceder ReflectionPermission a código de Internet.
