deleting files

[troy]

Hello,

I have the following code that run in the page_load section:

private void Page_Load(object sender, System.EventArgs e)
{
/// Create uploads folder in the Virtua; directory if one doesnt exist
AppPath = Request.PhysicalApplicationPath + UploadDirectory;
if(!Directory.Exists(AppPath))
Directory.CreateDirectory(Request.PhysicalApplicationPath +
UploadDirectory + "\\");
if(File.Exists(AppPath+"\\uploaded.txt"))
File.Delete(AppPath+"\\uploaded.txt");
}

The File.Delete command throws an except if the uploaded.txt file exists in
the application path\uploads folder - i guess because it has no permissions
on on it. How do I over come this?

thanks

Hello,

File.Delete can throw 8 different exceptions. I think that we need to know
which one, so we do not have to guess what the problem is.

You are probably getting:

System.UnauthorizedAccessException

MSDN tells me that this happens for this:

The caller does not have the required permission.
-or-

path is a directory.

-or-

path specified a read-only file.


Is anything of this true? Can you please take a look at the file you are
trying to delete, and make sure that the account you are running ASP.NET
under has permissions to delete the file?

In windows XP give permissions to ASPNET user and in Windows 2003 use
NETWORK SERVICE user.

you can also look into using impersontation using your web.config
