计算总数并取数组中数字的平均值

这是我需要解决的问题:

1. 查找12分中的最高分
2. 找到12分中的最低值
3. 计算12个分数的总和
4. 从总分中减去最高分和最低值
5. 用总分除以10计算剩余10分的平均值
6. 输出平均值(格式为小数点后2位)

这就是我到目前为止所做的，除了计算总分和减去总分的最高和最低，我不确定我应该把代码放在哪里，我应该使用什么代码:

双[]分数= {8.7,9.3,7.9,6.4,9.6,8.0,8.8,9.1,7.7,9.9,5.8,6.9};

        Console.WriteLine("Numbers in the list:" + scores.Length);
        for (int index = 0; index < scores.Length; index++)
        {
            Console.WriteLine(scores[index]);
        }

        //highest number
        double high = scores[0];
        for (int index = 1; index < scores.Length; index++)
        {
            if (scores[index] > high)
            {
                high = scores[index];
            }
        }
        Console.WriteLine("Highest number =" + high);
        //lowest number
        double low = scores[0];
        for (int index = 1; index < scores.Length; index++)
        {
            if (scores[index] < low)
            {
                low = scores[index];
            }
        }
        Console.WriteLine("lowest number =" + low);
        //average of the scores
        double total = 0;
        double average = 0;
        for (int index = 0; index < scores.Length; index++)
        {
            total = total + scores[index];
        }
        average = (double)total / scores.Length;
        Console.WriteLine("Total=" + total);
        Console.WriteLine("Average=" + average.ToString("N2"));
        Console.ReadKey();
    }

double[] scores = { 8.7, 9.3, 7.9, 6.4, 9.6, 8.0, 8.8, 9.1, 7.7, 9.9, 5.8, 6.9 };
double calculatedValue = scores.Sum() - scores.Max() - scores.Min();

double[] scores = { 8.7, 9.3, 7.9, 6.4, 9.6, 8.0, 8.8, 9.1, 7.7, 9.9, 5.8, 6.9 };
double min = scores.Min();
double max = scores.Max();
double total = scores.Sum();
double result = total - min - max;

double[] scores = { 8.7, 9.3, 7.9, 6.4, 9.6, 8.0, 8.8, 9.1, 7.7, 9.9, 5.8, 6.9, 9.9, 5.8 };
var resultValue = scores.Where(e => e != scores.Max() && e != scores.Min()).Sum();
