相邻数字算法分组器

我已经重写了你的代码:

    public static string[] FormatInts(int[] ints)
    {
        Array.Sort(ints);
        List values = new List();

        for (int i = 0; i < ints.Length; i++)
        {
            int groupStart = ints[i];
            int groupEnd = groupStart;
            while (i < ints.Length - 1 && ints[i] - ints[i + 1] == -1)
            {
                groupEnd = ints[i + 1];
                i++;
            }
            values.Add(string.Format(groupEnd == groupStart ? "{0}":"{0} - {1}", groupStart, groupEnd));
        }
        return values.ToArray();
    }

然后:

/////////////////
int[] myInts = { 1,2,3,5,7,9,10,11,12,14 };
string[] result = FormatInts(myInts); // now result haves "1-3", "5", "7", "9-12", "14"
