跳出一个 while 循环并进入另一个 c#

Question

我的 while 循环有点卡住了。代码的两个部分都可以独立运行，但是，我似乎无法使两个 while 循环都运行。非常感谢任何帮助：

using System;
namespace week5task3 {
    class Program {
        public static void Main(string[] args)

        {
            double PriceEvery1 = 5;
            double PriceEvery2 = 4;
            double PriceEvery3 = 2.5;
            double Quantity = 10;
            int UserCounter = 0;

            Console.WriteLine("\n\nWidget Price Chart\n\n");
            Console.WriteLine("Quantity of Widgets\t\tPrice");

            while (UserCounter <= 100) {
                double Price1 = PriceEvery1 * Quantity;
                double Price2 = PriceEvery2 * Quantity;
                double Price3 = PriceEvery3 * Quantity;

                if (Quantity <= 50) {
                    Console.WriteLine("\t{0}\t\t\t{1:C}", Quantity, Price1);
                }

                if (Quantity >= 51 && Quantity <= 80) {
                    Console.WriteLine("\t{0}\t\t\t{1:C}", Quantity, Price2);
                }

                if (Quantity >= 81 && Quantity <= 100) {
                    Console.WriteLine("\t{0}\t\t\t{1:C}", Quantity, Price3);
                }
                Quantity += 10;
            }

            while (UserCounter >= 0) {
                try {
                    Console.WriteLine("Enter the amount of widgets you would like to purchase or press q to quit");
                    string temp = Console.ReadLine();
                    if (temp == "q") break;
                    if (temp == "Q") break;

                    int.TryParse(temp, out UserCounter);

                    double UserPrice;

                    if (UserCounter <= 50) {
                        UserPrice = UserCounter * 5;
                        Console.WriteLine("The price is {0:C}", UserPrice);
                    }

                    if (UserCounter >= 51 && UserCounter <= 80) {
                        UserPrice = UserCounter * 4;
                        Console.WriteLine("The price is {0:C}", UserPrice);
                    }

                    if (UserCounter > 80) {
                        UserPrice = UserCounter * 2.5;
                        Console.WriteLine("The price is {0:C}", UserPrice);
                    }


                } catch (Exception) {
                    Console.WriteLine("You have entered an incorrect value. Please enter a number or press q to quit");
                }
            }
        }
    }
}

使用 while (Quantity <= 100) 而不是 UserCounter <= 100。这将在打印价格 10 次迭代后退出循环。
