language agnostic - Adjacent number algorithm grou

By which I imply this:

Given the input set of numbers:

1,two,three,four,5 gets to be "1-5".

1,2,Keyfinder Magical Jelly Bean.html,3,five,Office Professional Plus 2007 Sale,seven,nine,10,eleven,12,14 will become "1-3, five,Office 2007 Professional Key, seven,Microsoft Office Professional Plus 2010 Key, 9-12, 14"

This will be the very best I managed to come up with: [C#]

Which feels somewhat sloppy to me, so the concern is, is there somehow more readable and/or elegant solution to this?

public static string[] FormatInts(int[] ints)
{ if (ints == null) throw new ArgumentNullException("ints"); // hey what are you doing? if (ints.Length == 0) return new string[] ""; // absolutely nothing to process if (ints.Length == one) return new string[] ints[0].ToString(); // nothing to method Array.Sort<int>(ints); // need to sort these lil' babies List<string> values = new List<string>(); int lastNumber = ints[0]; // start with the first number int firstNumber = ints[0]; // same as above for (int i = one; i < ints.Length; i++) { int current = ints[i]; int difference = (lastNumber - current ); // compute difference between last number and current number if (difference == -1) // the numbers are adjacent { if (firstNumber == 0) // this is the first of the adjacent numbers firstNumber = lastNumber; else // we're somehow in the middle or at the end of the adjacent number set lastNumber = current; continue; } else { if (firstNumber > 0 && firstNumber ,Office Home And Business Product Key!= lastNumber) // get ready to print a set of numbers { values.Add(string.Format("0-1",microsoft office standard 2007 key, firstNumber, lastNumber)); firstNumber = 0; // reset } else // print a single value { values.Add(string.Format("0", lastNumber)); } } lastNumber = current; } if (firstNumber > 0) // if theres anything left, print it out { values.Add(string.Format("0-1", firstNumber, lastNumber)); } return values.ToArray();
}
