Convert JavaScript to C#

There is a JavaScript crossword app available at [login to view URL] It contains a working example and source code. The app can retrieve crossword files from varies websites: LA Times, the Independent's Concise, the Independent's Cryptic, and a few other. I would like to extract the code that retrieves those crossword files only (not the whole app) and convert it into C#. Basically, I would like a function: enum PuzzleType { LATimes, IndependentConcise, IndependentCryptic } String RetreivePuzzle(PuzzleType pType, DateTime dateTime) { ... } dateTime allows me to retrieve a puzzle for a selected date.
