" + pair.Value); } //descending sorted dictionary by keys. birds = birds.OrderByDescending(x => x.Key).ToDictionary(x => x.Key, x => x.Value); Console.WriteLine("descending sorted dictionary by keys.........."); foreach (KeyValuePair<int, string> pair in birds) { Console.WriteLine(pair.Key + " ........ " + pair.Value); } //ascending sorted dictionary by values. birds = birds.OrderBy(x => x.Value).ToDictionary(x => x.Key, x => x.Value); Console.WriteLine("ascending sorted dictionary by values.........."); foreach (KeyValuePair<int, string> pair in birds) { Console.WriteLine(pair.Key + " ........
