It's as simple as New / Project and selecting Windows Service from the templates available. Well... almost. ;-)

It seems that basic string manipulation is enough for this case, but otherwise, you may take a look at the classes on the System.Text.RegularExpressions namespace. A lot of power at your hands.

Best luck!
