Given an input string (of no more than 300 characters in length), parse the string and count the occurrences of vowels and consonants. The data should be output in the format below. Punctuation should be ignored. {vowels:<count>,consonants:<count>} eg:

Challenge.cs

    public class Challenge
    {
        public static void Main()
        {
            Console.WriteLine("Enter String Name");
            string inputString = Console.ReadLine();
            string alphabet = new String(inputString.Where(Char.IsLetter).ToArray());
            int vowel = CountVowels(alphabet);
            int consonants = CountConsonants(alphabet);         
            Console.WriteLine("{0}vowels:{1},consonants:{2}{3}", "{", vowel, consonants, "}");
            Console.Read();
        }

       public static int CountVowels(string value)
        {
            const string vowels = "aeiou";
            return value.Count(chr => vowels.Contains(char.ToLowerInvariant(chr)));
        }
       public static int CountConsonants(string value)
        {
            const string vowels = "aeiou";
            return value.Count(chr => !vowels.Contains(char.ToLowerInvariant(chr)));
        }
    }
