これが私のコードです：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Exercise8
{
    class Program
    {
        static void Main(string[] args)
        {

            //declare variables

            int casesSold;
            int costPerCase = 5; //Each case costs the Computer Club $5
            int numBars = 12; //There are 12 candy bars in each case

            double salePrice;
            double forSGA = .9; //The Student Government Association (SGA) will collect 10% of the earnings that the Computer Club makes

            string aCasesSold;
            string aSalePrice;

            //ask user for information

            Console.WriteLine("Please enter how many cases were sold:  ");
            aCasesSold = Console.ReadLine();

            Console.WriteLine("Please enter the sale price per candy bar: ");
            aSalePrice = Console.ReadLine();

            //Convert ints to strings so that they can be a part of the calculations

            casesSold = int.Parse(aCasesSold);
            salePrice = double.Parse(aSalePrice);

            //calculate total cost for the Computer Club

            public static double CalculateTotalCost(double totalCost, int costPerCase, int casesSold)

            {
               totalCost = costPerCase * casesSold;
               return totalCost; 

            }

            //calculate earnings for the Computer Club

            public static double CalculateEarnings(int numBars, int casesSold, double earnings, double salePrice)

            {

                earnings = numBars * salePrice * casesSold;
                return earnings;

            }

            //calculate proceeds

            public static double CalculateProceeds(double proceeds, double forSGA, double earnings, double totalCost)

            {

                proceeds = (forSGA * earnings) - totalCost;
                return proceeds;

            }

            //output proceeds to user

            public static void Output()

            {

                Console.WriteLine("The proceeds for the Computer Club are: {0;C}", CalculateProceeds());

            }
    }
}

何らかの理由で、次の 2 つのエラーが発生します。

の最後に「}が期待されます」salePrice = double.Parse(aSalePrice);

と

「メソッド 'CalculateProceeds' のオーバーロードは 0 引数を取ります」

コンソールにエンディングパートを書く方法がわかりません。助けてもらえますか? また、Visual Studio が末尾に「}」を追加する必要があると考える理由もわかりませんsalePrice = double.Parse(aSalePrice);

事前にご協力いただきありがとうございます。

CalculateProceeds のメソッド シグネチャは 4 つの引数を受け入れます

public static double CalculateProceeds(double proceeds, double forSGA, double earnings, double totalCost)

しかし、これらの引数をメソッドに渡さずに呼び出そうとしています

Console.WriteLine("The proceeds for the Computer Club are: {0;C}", CalculateProceeds());

また、動作しないメイン メソッド内でメソッドを宣言しています。

メソッドの終了が欠落して}おりmain、への呼び出しにCalculateProceeds()引数が欠落しています。
