用LINQ对Dictionary排序-创新互联

   static void Main(string[] args)
        {
            Dictionary di = new Dictionary();
            di.Add(9, 1);
            di.Add(0, 6);
            di.Add(2, 8);

var sortedDict = (from entry in di orderby entry.Key ascending select entry)
                .ToDictionary(pair=> pair.Key, pair => pair.Value);

foreach (var pair in di)
            {
                Console.WriteLine("{0},{1}", pair.Key, pair.Value);
            }

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

foreach (var pair in sortedDict)
            {
                Console.WriteLine("{0},{1}", pair.Key, pair.Value);
            }

            Console.ReadLine();
        }
