Does C# have built-in support for parsing page-number strings?

Question

Does C# have built-in support for parsing strings of page numbers? By page numbers, I mean the format you might enter into a print dialog that\'s a mixture of comma and das

Answer 1

The answer I came up with:

static IEnumerable ParseRange(string str)
{
    var numbers = str.Split(',');

    foreach (var n in numbers)
    {
       if (!n.Contains("-")) 
           yield return n;
       else
       {
           string startStr = String.Join("", n.TakeWhile(c => c != '-'));
           int startInt = Int32.Parse(startStr);

           string endStr = String.Join("", n.Reverse().TakeWhile(c => c != '-').Reverse());
           int endInt = Int32.Parse(endStr);

           var range = Enumerable.Range(startInt, endInt - startInt + 1)
                                 .Select(num => num.ToString());

           foreach (var s in range)
               yield return s;
        }
    }
}
