SortedList 、SortedDictionary、Dictionary元素添加耗时对比

public void DoTest()
    {
        Stopwatch sw = new Stopwatch();
        sw.Start();
        SortedDictionary<int, int> sdt = new SortedDictionary<int, int>();

        sdt.Add(4, 1);
        sdt.Add(6, 2);
        sdt.Add(5, 3);
        sdt.Add(3, 4);
        sdt.Add(2, 5);
        sdt.Add(9, 6);
        sdt.Add(1, 7);

        print(sdt);


        Console.WriteLine($"-------------------------{sw.ElapsedTicks}----------------------------");
        sw.Restart();

        Dictionary<int, int> sdt1 = new Dictionary<int, int>();

        sdt1.Add(4, 1);
        sdt1.Add(6, 2);
        sdt1.Add(5, 3);
        sdt1.Add(3, 4);
        sdt1.Add(2, 5);
        sdt1.Add(9, 6);
        sdt1.Add(1, 7);

        print(sdt1);

        Console.WriteLine($"-------------------------{sw.ElapsedTicks}----------------------------");
        sw.Restart();

        SortedList<int, int> sl = new SortedList<int, int>();
        sl.Add(4, 1);
        sl.Add(6, 2);
        sl.Add(5, 3);
        sl.Add(3, 4);
        sl.Add(2, 5);
        sl.Add(9, 6);
        sl.Add(1, 7);

        print(sl);


        Console.WriteLine($"-------------------------{sw.ElapsedTicks}----------------------------");
        sw.Stop();

    }

    void print<K,V>(IDictionary<K,V> dic)
    {
        foreach (var item in dic)
        {
            Console.WriteLine($"{item.Key}---------{item.Value}");
        }
    }

输出结果:

1---------7
2---------5
3---------4
4---------1
5---------3
6---------2
9---------6
-------------------------17616----------------------------
4---------1
6---------2
5---------3
3---------4
2---------5
9---------6
1---------7
-------------------------197----------------------------
1---------7
2---------5
3---------4
4---------1
5---------3
6---------2
9---------6
-------------------------5745----------------------------
