Question

当我运行此代码时：

Console.Write("How many numbers do you wish to enter? ");
    int n = int.Parse(Console.ReadLine());

    int[] arrayOfNumbers = new int[n];

    for (int i = 0; i < n; i++)
    {
        Console.Write("Enter number [{0}]: ", i + 1);
        arrayOfNumbers[i] = int.Parse(Console.ReadLine());
    }

    int minNumber = arrayOfNumbers[0];
    int maxNumber = arrayOfNumbers[0];
    int sumOfNumbers = 0;

    for (int i = 0; i < n; i++)
    {
        if (arrayOfNumbers[n] < minNumber)
        {
            minNumber = arrayOfNumbers[n];
        }
        else if (arrayOfNumbers[n] > maxNumber)
        {
            maxNumber = arrayOfNumbers[n];
        }

        sumOfNumbers += arrayOfNumbers[n];
    }

    double sumDouble = (double)sumOfNumbers;
    double average = sumDouble / n;

    Console.Write("The min number is : {0}", minNumber);
    Console.Write("The max number is : {0}", maxNumber);
    Console.Write("The sum of the numbers is : {0}", sumOfNumbers);
    Console.Write("The average sum of the numbers is : {0:f2}", average);

它给我一个错误：索引超出了数组的范围。

错误在第28行。

我有一项任务是找到最小和最大数字+总和和'n'数字的平均值。

在for中，你必须替换变量＆＃39; n＆＃39;通过＆＃39; i＆＃39;。

像这样：

(...)

for (int i = 0; i < n; i++)
{
    if (arrayOfNumbers[i] < minNumber)
    {
        minNumber = arrayOfNumbers[i];
    }
    else if (arrayOfNumbers[i] > maxNumber)
    {
        maxNumber = arrayOfNumbers[i];
    }

    sumOfNumbers += arrayOfNumbers[i];
}

(...)

错误：索引超出了数组的范围
