How to close the File after it is read from backward?
<p>I asked a question about "How to read a text file reversely with iterator in C#" sometime ago. <a href="http://stackoverflow.com/questions/452902/how-to-read-a-text-file-reversely-with-iterator-in-c">Please see the link</a></p>

<p>Jon Skeet was very kind to provide a solution for me. But I still have a question how to close the data file when it is read? It seemed that Jon used a delegate to handle the iterator, which was very interesting. But How I can call something like "file.Close()" to release it when the file was processed?</p>

<p>Thanks,</p>
