.net 中Dictionary的遍历

            Dictionary<int, int> dict = new Dictionary<int, int>();
            dict.Add(200, 1);
            dict.Add(100, 2);
            dict.Add(50, 3);
            dict.Add(20, 4);
            foreach( KeyValuePair<int,int> entry in dict)
            {
                Console.WriteLine(string.Format("key:{0}\nvalues:{1}\n", entry.Key, entry.Value));
            }
