使用IComparer进行随机播放

using System;
using System.Collections.Generic;

class RandomComparer<T> : IComparer<T>
{
    private Random _random = new Random();

    public int Compare(T x, T y)
    {
        return _random.Next(2) == 0 ? -1 : 1;
    }
}

class Program
{
    static void Main(string[] args)
    {
        List<int> list = new List<int> { 1, 2, 3, 4, 5 };
        list.Sort(new RandomComparer<int>());

        foreach (int item in list)
        {
            Console.WriteLine(item);
        }
    }
}
