尝试在 C# 程序中为平均股票计算器定义两个数字时出现问题

namespace average_stock_calculator
{
    class Program
    {
        static void Main(string[] args)
        {
            decimal  a, b, c, d, sum, average;
         

            Console.WriteLine("First purchase price:");
         
            a = Convert.ToDecimal(Console.ReadLine());
            
            Console.WriteLine("Second purchase price:");
            b = Convert.ToDecimal(Console.ReadLine());

            Console.WriteLine("Third purchase price:");
            c = Convert.ToDecimal(Console.ReadLine());

            Console.WriteLine("Fouth purchase price:");
            d = Convert.ToDecimal(Console.ReadLine());

            //Processing
            sum = a + b + c + d;
            average = sum/4;
            
            Console.WriteLine("Average buying price={0}", average);

            Console.ReadKey();
        }
    }
}

注意：我想把首购数量和首购价格加在一起，不知道怎么办！有人可以帮忙吗？它应该看起来像这样，输入首次购买数量和价格我应该能够一起输入数量 10 和价格 20，然后最后我应该得到平均购买数量和价格。

我给你做了简单的修改

代码：

using System;

namespace ConsoleApp9
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Purchase a, b, c, d;
            Console.WriteLine("First purchase price and amount:");
            a = ReadL();
            Console.WriteLine("Second purchase price and amount:");
            b = ReadL();
            Console.WriteLine("Third purchase price and amount:");
            c = ReadL();
            Console.WriteLine("Fouth purchase price: and amount:");
            d = ReadL();

            //Processing
            Purchase Sum = new Purchase();
            Sum.price = a.price + b.price + c.price + d.price;
            Sum.amount = a.amount + b.amount + c.amount + d.amount;

            Purchase Average = new Purchase();
            Average.price = Sum.price / 4;
            Average.amount = Sum.amount / 4;

            Console.WriteLine("Average buying price={0},Average buying amount={1}", Average.price, Average.amount);

            Console.ReadKey();

            Purchase ReadL()
            {
                Purchase X = new Purchase();
                var inputs = Console.ReadLine().Split(' ');
                X.amount = Convert.ToDecimal(inputs[0]);
                X.price = Convert.ToDecimal(inputs[1]);
                return X;
            }
        }
        class Purchase
        {
            public decimal price { get; set; }
            public decimal amount { get; set; }
        }
    }
}
