Nell'esempio di codice seguente viene illustrato l'uso del SetPathList metodo .

// 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.
