ASP.NET Function to Check user has read access to a file

[Raed Sawalha]

Hi all,

I need a function which will return read access for the current user as true or false when a file path is passed to it (either local or UNC share).

My web-config file is using windows authentication and impersonate = true. The idea is to check that the user has access to each file before displaying it in a list.

Thanks for any help!

I would think FileIOPermissio n might help you. See help for that class and
related Security demands and asserts to see if they help you out.
