Ejemplos
En el ejemplo de código siguiente se muestra el uso del GetPathList método .
// AddPathList adds access for the specified registry variables to the existing state of the permission.
// SetPathList sets new access for the specified registry variable names to the existing state of the permission.
// GetPathList gets paths for all registry variables with the specified RegistryPermissionAccess.

Comentarios
Use este método para obtener el estado del permiso actual. Debe llamar a este método por separado para cada tipo de acceso.
Nota
El access parámetro se limita a los valores de RegistryPermissionAccess, que representan tipos únicos de acceso a variables del Registro. Esos valores son Read, Writey Create. Los valores aceptables para access no incluir NoAccess y AllAccess, que no representan tipos únicos de acceso a variables del Registro.
