Simon Cheng

Hi,

I am getting the following error when trying to read an XML file. Is there
some setting in web.config or machine.config that needs to be set?

Thanks,
- Simon

Hello Simon,

seems you are running in partial trust. Is this a hosted environment?

Hello Simon,

then you have to contact your provider to get the policy settings - seems
you are not allowed to read files...
