title: Tuples( or arrays ) as Dictionary keys in C#
body: <p>I am trying to make a Dictionary lookup table in C#.  I need to resolve a 3-tuple of values to one string.  I tried using arrays as keys, but that did not work, and I don't know what else to do.  At this point I am considering making a Dictionary of Dictionaries of Dictionaries, but that would probably not be very pretty to look at, though it is how I would do it in javascript.</p>
