Question

我已经完成了大部分代码，但最后一部分现在已经混乱了大约2个小时。我试图通过减去他们吃的食物/零食的卡路里所允许的卡路里来向用户显示剩余的卡路里，他们说是“是”以继续。我每次都会收到错误。非常感谢任何帮助！

                {

                }
                double caloriesAllowed = BMR * exerciseFactor;
                string response = "YES";
                while (response == "YES");
                var calconsumed = 0;
                {
                    Console.WriteLine ("Enter the amount of calories consumed: ");
                    calconsumed = Convert.ToInt32 (Console.ReadLine ());
                    Console.WriteLine ("Your remaining calories are:" + caloriesAllowed - calconsumed);
                    Console.WriteLine("Do you want to continue? (YES / NO)");
                    response = Console.ReadLine().ToUpper();
                        response = response.ToUpper();
                    }
                }
        }
    }
}

如果用户键入YES继续，则现在不循环。如何让这段代码循环？

            {
            double caloriesAllowed = BMR * exerciseFactor;
            var calconsumed = 0;
            string response = "YES";
                do {

                    Console.WriteLine ("Enter the amount of calories consumed: ");
                    Console.WriteLine ("Your remaining calories are:" + (caloriesAllowed - calconsumed));
                    calconsumed = Convert.ToInt32 (Console.ReadLine();
                    Console.WriteLine ("Do you want to continue? YES or NO: ");
                    Console.ReadLine ();
                    response = Console.ReadLine().ToUpper();

                } while (response == "YES");

你构建一个空的无限循环，因为你在while条件之后使用分号而不是大括号。

这应该有效

        string response = "YES";
          var calconsumed = 0;
        while (response == "YES")
        {

            Console.WriteLine("Enter the amount of calories consumed: ");
            calconsumed = Convert.ToInt32(Console.ReadLine());
            Console.WriteLine("Your remaining calories are:" + (caloriesAllowed - calconsumed));
            Console.WriteLine("Do you want to continue? (YES / NO)");
            response = Console.ReadLine().ToUpper();
            response = response.ToUpper();
        }
