你好，我们目前正在做一个数组任务，但我是c#的新手

我们必须找到用户输入的5个数字的平均值和或总和，但我不确定如何做到这一点。任何帮助都是感激的!这是我到目前为止的代码:基本上，我需要帮助完成输入的数字的总和，以及如何使用稍后在代码中输入的数字的数组，考虑到它声明'int unassigned'。

{
    class Program
    {
        static void Main(string[] args)
        {
            int numofnum;
            int[] numbers = new int[numofnum];
            int index;
            string avsu;
            int average;
            index = 0;
            Console.WriteLine("Please enter the number of numbers you would like to find the average for, or add together: ");
            numofnum = int.Parse(Console.ReadLine());

            Console.WriteLine("Would you like to find the average or sum of these numbers? (average/sum)");
            avsu = Console.ReadLine();

            if (avsu == "average")
            {

            do 
            {
                Console.Write("Please enter Number to find the average of: " + index);
                numbers[index] = int.Parse(Console.ReadLine());
                index = index + 1;
            } while (index < numofnum);
            index = 0;
            do
            {
                Console.WriteLine("You entered the following values: ");
                Console.WriteLine("Number " + index + ": " + numbers[index]);
                index = index + 1;
                Console.WriteLine("The average of these numbers is: " + (numbers[index] / 2));
            } while (index < numofnum);
                else if (avsu == "sum")
            {

            do 
            {
                Console.Write("Please enter Number " + index + " to add: ");
                numbers[index] = int.Parse(Console.ReadLine());
                index = index + 1;
            } while (index < numofnum);
            index = 0;
            do
            {
                Console.WriteLine("You entered the following values: ");
                Console.WriteLine("Number " + index + ": " + numbers[index]);
                index = index + 1;
                Console.WriteLine("The sim of these numbers is: " + (numbers[index])); // UNSURE HOW TO DISPLAY THE SUM!!!!
            } while (index < numofnum);
            Console.ReadLine();
            }

        }
    }
}

这有帮助吗?

static void Main(string[] args)
{
    Console.WriteLine(
        "Please enter the number of numbers you would like to find the average for, or add together: ");
    int numofnum = int.Parse(Console.ReadLine());
    int[] numbers = new int[numofnum];
    Console.WriteLine("Would you like to find the average or sum of these numbers? (average/sum)");
    var avsu = Console.ReadLine();
    var sum = 0;
    if (avsu != "average" && avsu != "sum")
    {
        return;
    }
    for (var i = 0; i < numofnum; i++)
    {
        Console.Write("Please enter Number " + i + " to add: ");
        numbers[i] = int.Parse(Console.ReadLine());
    }
    for (var i = 0; i < numofnum; i++)
    {
        Console.WriteLine("You entered the following values: ");
        Console.WriteLine("Number " + i + ": " + numbers[i]);
    }
    if (avsu == "sum")
    {
        sum = numbers.Sum();
        Console.WriteLine("The sim of these numbers is: " + sum);
    }
    if (avsu == "average")
    {
        var average = sum / numbers.Length;
        Console.WriteLine("The average of these numbers is: " + average);
    }
}
