排序方法：去掉最高最低分求平均分

static void Main(string[] args)
{
double[] a = new double[10];
double sum = 0;
for (int i = 0; i < a.Length; i++)
{
a[i] = Convert.ToInt32(Console.ReadLine());
sum=sum+a[i];
Console.WriteLine("第"+(i+1)+"个评委的分数为"+a[i]);
}
Console.WriteLine("总分为"+sum);
double temp;
for (int i = 0; i <a.Length; i++)
{
for (int j = i; j <a.Length-1; j++)
{
if (a[i]<a[j+1])
{
temp = a[i];
a[i] = a[j + 1];
a[j + 1] = temp;
}
}
}
for (int i = 0; i < a.Length; i++)
{
Console.Write("分数从大到小为："+a[i]+"\n");
}
Console.WriteLine("最高分" + a[0]);
Console.WriteLine("最低分" + a[9]);
double pj = (sum - a[0] - a[9]) / (a.Length - 2);//for(int i = 1;i<a.Leagth-1;i++)→double pj
Console.WriteLine("去掉一个最高分和最低分之后的平均最后得分为" + pj);
Console.ReadLine();
