slet filer permanent.

Hejsa
Hvordan sletter jeg filer permanent. Det vil sige uden at filerne ryger i Recycle Bin (Skraldespand)?

Nedenstående kode flytter samtlige filer i Recycle Bin. Jeg ønsker at slette filerne permanent... How?

        // Delete all files. Leave Directory empty
        public void DeleteFilesInDirectory(string path)
        {
            // Delete all files from the Directory
            if (Directory.Exists(path))
            {
                foreach (string file in Directory.GetFiles(path))
                {
                    System.IO.File.Delete(file);
                }
                foreach (string directory in Directory.GetDirectories(path))
                {
                    DeleteDirectoryWithFiles(directory, "");
                }
            }
        }

        // Delete all files and the corresponding Directortory.
        public void DeleteDirectoryWithFiles(string path, string notDeletePath)
        {
            // Delete all files from the Directory
            if (Directory.Exists(path))
            {
                foreach (string file in Directory.GetFiles(path))
                {
                    System.IO.File.SetAttributes(file, FileAttributes.Normal);
                    System.IO.File.Delete(file);
                }
                foreach (string directory in Directory.GetDirectories(path))
                {
                    try
                    {
                        DeleteDirectoryWithFiles(directory, "");
                    }
                    catch (Exception ex)
                    {
                        log.ErrorLog(logpath, "DeleteDirectoryWithFiles failed. Path: " + path);
                        log.ErrorLog(logpath, ex.ToString());
                    }
                }
            }
            // Delete a empty directory
            if (Directory.Exists(path) && path != notDeletePath)
                Directory.Delete(path);
