The FileIOPermissionAccess enumeration contains
values that are used with the FileIOPermission
class to specify the type of access represented by a
FileIOPermission object. Read
represents permission to read from a file or folder, and
Write represents permission to write to, delete,
or overwrite files and folders; Write does not
encompass the ability to Read.
Append represents the ability to append material
to a file or folder, as well as to create new folders. The
PathDiscovery value represents the ability to
access information from a file or folder's path,
which could provide username and folder structure information that
would be useful to malicious code. AllAccess
includes the combined permissions of the Read,
Write, Append, and
PathDiscovery values.
