Hi everybody,
Everytime i try to run file-operation(create/read from file) code in C# i get this error
-------------------------------------------------------------------
An unhandled exception of type 'System.Security.SecurityException' occurred in mscorlib.dll

Additional information: Request for the permission of type System.Security.Permissions.FileIOPermission, mscorlib, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed.
--------------------------------------------------------------------
I understand that this is a permission error. I tried changing permissions to the file but even that wont help.

Can somebody help me out with this?

Thnx

What changes did you make?

added 'everyone' in the user names of security tab in properties and gave required permissions to this user.

Mrinal

Everyone refers to domain accounts if I'm not mistaken.

Is this a web app or a windows app?
