How can you delete a file from the Session_End event in the global.asax?

I may be completely off base, but I am needing to use the Session_End event in the global.asax to delete some files.

I have set the sessionState mode to "InProc" in the web.config and done the necessary things to have the event fire. I just cannot figure out what code to use, if possible, to delete the files from the location in which I created them. They only need to be temporary and I don't want disk space to be taken up nor have a messy folder.

I would appreciate any advice and/or examples. Thank you.

C#

protected void Session_End(Object sender, EventArgs e)
{
   DirectoryInfo d = new DirectoryInfo(session["sFileName"].ToString());
   foreach (FileInfo f in d.GetFiles())
   {
      if (f.CreationTime.AddHours(1) < DateTime.Now)
      File.Delete(f.FullName);
   }
}

Thank you for that info, but when I add that to my global.asax it does not recognize the DirectoryInfo. Do I need a using directive or something?

Yes. Use Namespace: System.IO

Ok, I solved that issue, now I just have a question about the session["sFileName"]. Is that a session variable with the file path I set in my code-behind?

I cannot get this to work, does anyone else have an idea on how to do this?
