需要帮助以单独的方法访问数组的特定值

Question

我需要帮助在单独的方法中访问数组的特定值。在这个程序中，我应该编写一个程序，要求用户输入日历年每个月的降雨量。该程序随后将确定年度总降雨量和平均每月降雨量，最后将允许用户搜索特定数量。

我应该为最后一个方法执行此操作：SearchForAmounts() – 此方法将是一个 void 方法，并且有两个双精度数组作为参数列表，一个用于降雨量数组，一个用于带有月份的数组。它会要求用户在数组中搜索降雨量。然后它将报告该数量在哪个月首次下降或者它将报告说那一年没有下那么大的雨。它将使用 Array class 方法之一来确定要输出的内容。它会在方法中执行两次 - 即会在方法中重复代码两次。

我无法找到一种方法来访问 monthInTheYear 数组中的值。这是我的代码：

namespace CJohnson_Prog8
{
    class Program
    {
        static void Main(string[] args)
        {

            string[] monthInTheYear;
            double[] rainfallAmmounts;

            monthInTheYear = new string[12] { "January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" };
            rainfallAmmounts = new double[12];

            Console.WriteLine("Welcome to the Annual Rainfall Program");
            GetRainFall(rainfallAmmounts, monthInTheYear);

            PrintAmounts(rainfallAmmounts, monthInTheYear);
            TotalYearRain(rainfallAmmounts);
            SearchForAmounts(rainfallAmmounts, monthInTheYear);

        }

        public static void GetRainFall(double[] rainfall, string[] month)
        {
            for (int i = 0; i < rainfall.Length; i++)
            {
                Console.Write("Enter the rainfall in inches in {0}: ", month[i]);
                rainfall[i] = double.Parse(Console.ReadLine());

                while (rainfall[i] < 0)
                {
                    Console.Write("Enter the rainfall in inches in {0}: ", month[i]);
                    rainfall[i] = double.Parse(Console.ReadLine());
                }
            }
        }

        public static void PrintAmounts(double[] rainfall, string[] month)
        {
            for (int i = 0; i < rainfall.Length; i++)
            {
                Console.WriteLine("{0}\t\t{1:F2}", month[i], rainfall[i]);
            }
        }

        public static double TotalYearRain(double[] totalrainFall)
        {
            double averageRainFall;
            double sum = 0;
            for (int i = 0; i < totalrainFall.Length; i++)
            {
                sum += totalrainFall[i];
            }
            averageRainFall = sum / 12;
            Console.WriteLine("");
            Console.WriteLine("Total Annual Rain is: {0:F2}", sum);
            Console.WriteLine("Average Month Rain:  {0:F2}", averageRainFall);
            return sum;
        }

        public static void SearchForAmounts(double[] searchRainFall, string[] searchMonths)
        {


                Console.Write("Enter a rainfall amount to search for: ");
                double RainFall = double.Parse(Console.ReadLine());


                if (Array.IndexOf(searchRainFall, RainFall) != 1)
                {
                    Console.WriteLine(searchMonths[i] + " was the first month to have " + RainFall + " inches fell this year.");
                }
                else
                {
                    Console.WriteLine("No rainfall of " + RainFall + " inches fell that year.");
                }

        }



        }
    }

Answer 1

for (int i = 0; i <= 1; i++) {
    //do stuff
    var index = Array.IndexOf(searchRainFall, RainFall);
    if (index > -1) {
        Console.WriteLine(searchMonths[index] + " was the first month to have " + RainFall + " inches fell this year.");
    } else {
        Console.WriteLine("No rainfall of " + RainFall + " inches fell that year.");
    }
}
