Re: File IO Permissions
FileIOPermission has nothing to do with OS ACLs/Privileges - it is a CAS
thing - which is a different security model.
I am not aware of a good way of doing those checks - besided trying to open
the file - and see if an exception gets thrown.

Hi all,
I am trying to write a piece of code that will allow me to check if
the
current user has permission to access (read, write, etc.) a certain
folder
before I try to access it for the read, write, etc. I tried to use
FileIOPermission class and the Demand method, but it doesn't appear to
break if the user doesn't have permission. Any help would be
appreciated.
Thanks!
