c# - 显示两个最大的 N 个数字 c#

Question

我有一个问题，我想知道如何在控制台上显示 N 个输入数字中最大的 2 个？我正在做这样的事情:

Console.WriteLine("Enter the weight of the fish:");
if(decimal.TryParse(Console.ReadLine(), out _fishWeight))
{
    if (_fishWeight > _highest2)
    {
        _highest = _fishWeight;
        if (_fishWeight < _highest1)
        {
            _highest = _fishWeight;
        }
    }       
} 

但它不起作用。它只向我显示 _highest1，但不显示其他 _highest...

如果有人能帮助我，我会很高兴!

Answer 1

你想要更像的东西

if (_fishweight > _highest)
{
    _highest2 = _highest;
    _highest = _fishweight;
}
else if(_fishweight > _highest2)
{
    _highest2 = _fishweight;
}

或者，如果您想要更灵活的排行榜

// declare something like...

    private List<int> _leaderboard = new List<int>();
    private readonly int _leaderboardCount = 2;

// then update it like...    
    _leaderboard.Add(_fishweight);
    _leaderboard = _leaderboard.OrderByDescending(v => v).Take(_leaderboardCount).ToList();

现在您已经获得了前 2 名，但如果您愿意，稍后您可以轻松地将其更改为前 10 名。
