    Hi all, I'm trying to enumerate files in a server directory and I receive a security exception error; I have opened a ticket: here below the thread.
    If you have a solution to successfully enumerate a server directory please let me know ( I just need to fill a string array with directory's filenames).

    Any help is appreciated.
    Best regards.
    Claudio


    Here the ticket history thread:


    Dear Customer,
    </o:p>
    The IUSR / ASPNET users already have change permission on your site.
    </o:p>
    The error you are seeing indicates that your application is trying to retrieve the permission on the file / directory which is not permitted.
    </o:p>

    I think you need to pass the entire physical path of the directory that you want to search. For example,

    Directory.GetFiles("C:\folder\images", "*.png")

    You can find the physical path of your site's rootin the Account Info page of your hosting control panel.
