I made a console application in Visual Studio that reads a flat file from our customer and updates the oracle database depending on the received data.
I use streamreader / writer to read and write some files.
When I run my exe file locally everthing works fine. When this exe is run on the application server this gives following error message :
Unhandled Exception: System.Security.SecurityException: Request for the permiss
on of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0
