Elegant Python Solution:

from collections import Counter
def stringCounts(words):
  for word in words:
    c = Counter(word)
    # First sort by counts, then by alphabet
    orderedLetters = sorted(c.items(), key=lambda elem:(-elem[1],elem[0]))
    print('%s: %s' % (word, orderedLetters))

stringCounts(['hello', 'world'])
# Output:
# hello: [('l', 2), ('e', 1), ('h', 1), ('o', 1)]
# world: [('d', 1), ('l', 1), ('o', 1), ('r', 1), ('w', 1)]

C# solution:

public static void PrintHightestCountOrdered(string input)
        {
            //int multiplier = 100;
            if (input == null)
                Console.WriteLine("Invalid input!!!");

            Dictionary<char, int> dictionary = new Dictionary<char, int>();

            foreach(var inputar in input.Split(' '))
            {
                foreach (char chr in inputar)
                {
                        
                    if (dictionary.ContainsKey(chr))
                        dictionary[chr]++;
                    else
                        dictionary.Add(chr, 1);
                }

                var items = from entry in dictionary
                            orderby entry.Value descending, entry.Key ascending
                            select entry;

                dictionary = new Dictionary<char, int>();

                foreach(var item in items)
                {
                    Console.WriteLine($"{item.Key} - {item.Value} ");
                }

                Console.WriteLine("--------------------");
            }
