Hello Marquis,
The recommended way to resolve this is to sign the assembly in question
using a strong name key pair (created using the SN.exe tool) and create a
separate .NET Security Policy code group for the aforementioned assembly.
This code group would be given FullTrust, or at least file I/O permissions.
You can read the steps to achieve this at MSDN Blogs
( http://blogs.msdn.com/shawnfa/archiv...20/57023.aspx).

Hi NG !
I have the following piece of code below. the first try/catch part
would return true although I do not have permission to access this
computer. The second try/catch part would return false.
Do I misunderstand the meaning of FileIOPermission ?
>From MSDN: "Controls the ability to access files and folders"
???
Thanks for education!

Hi,
I'm trying to test permission to access the file system, using
FileIOPermission, but can't seem to get it to work.
See my sample app below, for an app that tries to demand a permission
to read a specified path, and then calls Directory.GetFiles on that
path.
The Demands on FileIOPermissions (I tried 3 variations) all work, and
then when I call Directory.GetFiles an exception is thrown... saying
