This class is a subclass of the CodeGroup class.
FileCodeGroup does not support attributes and does
not contain a statically defined permission set, and so there is no
need to assign it a PolicyStatement. With each
call to Resolve( ), the
FileCodeGroup object determines if the provided
Evidence collection contains
Url evidence that represents a URL with the
"file://" protocol. If so, the
FileCodeGroup dynamically generates a permission
set that contains a
System.Security.Permissions.FileIOPermission that
grants access to the directory specified in the
Url evidence. The type of file access to grant
(read, write, and so on) is specified in the
FileCodeGroup constructor using a member of the
System.Security.Permissions.FileIOPermissionAccess
enumeration.
Members of a FileCodeGroup are tested for
membership against all of its child code groups. The final permission
set granted by the FileCodeGroup is the union of
its permission set and the permission sets of the children to which
the assembly or application domain also qualifies for membership.
