Lucene.Net fails at my host because it calls GetTempPath(). What's the work around?

Question

I\'m using Lucene.Net in an ASP.NET application on a shared host. Got this stack trace shown below. What\'s the work around?

Here's the answer to my own question. The solution was to modify Lucene.Net.Store.FSDirectory, by commenting out this unused line:

// Comments out by Corey Trager, Oct 2008 to workaround permission restrictions at shared host.  This is not used.
//        public static readonly System.String LOCK_DIR = SupportClass.AppSettings.Get("Lucene.Net.lockDir", System.IO.Path.GetTempPath());

There was one more security permission hurdle after that, and here's that workaround too. I don't understand why one way of getting the names of files in a directory would be blocked, and another way not blocked.

    public override System.String[] List()
    {

/* Changes by Corey Trager, Oct 2008, to workaround permission restrictions at shared host */
            System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(directory.FullName);
            System.IO.FileInfo[] files = dir.GetFiles();
            string[] list = new string[files.Length];
            for (int i = 0; i < files.Length; i++)
            {
                list[i] = files[i].Name;
            }
            return list;
/* end of changes */

//            System.String[] files = SupportClass.FileSupport.GetLuceneIndexFiles(directory.FullName, IndexFileNameFilter.GetFilter());
//            for (int i = 0; i < files.Length; i++)
//            {
//                System.IO.FileInfo fi = new System.IO.FileInfo(files[i]);
//                files[i] = fi.Name;
//            }
//            return files;
        }
