如何排除数组的值？

Question

如何创建排除最低温度并计算平均温度的方法.我只想要一个提示,而不是完整的解决方案,因为我想自己解决我的编程问题.我只有大约10个班级...评论人们的评论我的教授没有讲课,我读过我的书多次回顾过它.

我让这个程序从用户那里拿一个号码.该数字将添加到数组中.该数组用于创建类的实例Temp以打印最低和最高临时值.

class Program
{
    static void Main(string[] args)
    {
        Console.Write("Enter a Temperature in Degrees:");
        string n = Console.ReadLine();
        int number = Convert.ToInt32( n); 
        Temp t = new Temp(100, 52, 98, 30, 11, 54, number);
        Console.WriteLine("Lowest Temperature:{0}", t.lowest());
        Console.WriteLine("Highest Temperature: {0}", t.highest());
        Console.WriteLine("Average Temperature: {0}", t.Average());
    }

    public class Temp
    {
        private int[] temp = new int[7]; // array 
        public Temp(int d1, int d2, int d3, int d4, int d5, int d6, int d7) // constructor with 7 parameters
        {
            temp[0] = d1; // assigning constructor parameters to array
            temp[1] = d2;
            temp[2] = d3;
            temp[3] = d4;
            temp[4] = d5;
            temp[5] = d6;
            temp[6] = d7;
        }

        public int lowest() // returning the lowest value of the set of numbers
        {
            int smallest = 150;
            for (int c = 0; c < 7; c++)
            {
                if (temp[c] < smallest)
                {
                    smallest = temp[c];
                }

            }
            return smallest;
        }

        public int highest()
        {
            int highest = -1;
            for (int c = 0; c < 7; c++)
            {
                if (temp[c] > highest)
                {
                    highest = temp[c];
                }
            }

            return highest;
        }

        public double Average()
        {
            double average = 0;
            for (int c = 0; c < 7; c++)
            {

            }
            return average;
        }
    }
}

使用单个循环非常容易:

public double Average()
{
    // Initialize smallest with the first value.
    // The loop will find the *real* smallest value.
    int smallest = temp[0];

    // To calculate the average, we need to find the sum of all our temperatures,
    // except the smallest.
    int sum = temp[0];

    // The loop does two things:
    // 1. Adds all of the values.
    // 2. Determines the smallest value.
    for (int c = 1; c < temp.Length; ++c)
    {
        if (temp[c] < smallest)
        {
            smallest = temp[c];    
        }
        sum += temp[c];
    }
    // The computed sum includes all of the values.
    // Subtract the smallest.
    sum -= smallest;

    double avg = 0;
    // and divide by (Length - 1)
    // The check here makes sure that we don't divide by 0!
    if (temp.Length > 1)
    {
        avg = (double)sum/(temp.Length-1);
    }
   return avg;
}
