        dic.Add("php", 44);
        dic.Add("c++", 888);
        dic.Add("java", 1);
 
        List<KeyValuePair<string, int>> list = dic.ToList();
 
        list.Sort((pair1, pair2) => pair1.Value.CompareTo(pair2.Value));
 
        foreach (var element in list)
            Console.WriteLine(element);
    }
}
