   FileInfo^ fi = gcnew FileInfo( "temp.txt" );
   
   // Determine the full path of the file just created.
   DirectoryInfo^ di = fi->Directory;
   
   // Figure out what other entries are in that directory.
   array<FileSystemInfo^>^fsi = di->GetFileSystemInfos();
   Console::WriteLine( "The directory '{0}' contains the following files and directories:", di->FullName );
   
   // Print the names of all the files and subdirectories of that directory.
   Collections::IEnumerator^ myEnum = fsi->GetEnumerator();
   while ( myEnum->MoveNext() )
