Thanks for the response Rajeev!

Now I understand that the ASPNET user was having
restricted access.

After providing proper permissions to the ASPNET user, it
worked. I did not receive an error when the code attempted
to access the file.

I tried to change the Code Access Security policy in my
machine and removed the FileIO Permission using
mscorcfg.msc for My_Computer_Zone code group. Even after I
did that, I did not receive an error when the code tried
to access the file. I could not understand why ASP.NET did
not throw an exception in this case. Could you please shed
some light on that?
