Hello,

I've suscribed a MSDN webhosting pack at ikoula.com and i get some troubles creating directories by code. I am trying to use those C# methods:

String p = MapPath("~/Docs/Fichiers/Dossier_test");
Directory.CreateDirectory(p);

But this System.Security.SecurityException is thrown:

Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.

 The most interesting part of the issue is that I am allowed to create and delete any file in ~/Docs/Fichiers/. I am also allowed to Delete directories but not to create them!

It seems that a permission has been forgotten by Ikoula. Am I the only one to be faced to this issue? Is there another way to create a directory?

Javier Luna:

You would have to setup writting permissions to ASPNET account.

Writing permissions are set, that's why I am able to create/delete files in this directory. I am also allowed to delete a directory.

For those who are familiar with Plesk (the administration interface of my web account at ikoula.com), Total control is set for this directory, files and sub-directories. But in the specific case of directory creation, this security exception occurs and I dont know why.

Am I alone in this case? 

Hi

 'System.Security.Permissions.FileIOPermission" means you should have had unrestricted permissions, please check the security level for your websites and sets it to a unrestricted set of permissions.  To fix it, added this line to Web.Config for the web site:

Thanks for helping me XiaoYong  

I would apreciate changing my trust level to Full but I am on a shared host. When I am trying to do so the Configuration Error message is very explicit:

Parser Error Message: This configuration section cannot be used at this path.  This happens when the site administrator has locked access to this section using <location allowOverride="false"> from an inherited configuration file.

It seems I wont ever override permissions set up by my hoster... Any other testing idea is welcome.

Hi

We suggest you'd better contact your ISP for this solution.
