[問題] switch..case

[followaymis (abcde)]

謝謝各位高手為我解答....

針對這個程式碼有些許的疑問...

煩請各位高手指點迷津...

            int degree, month;
            double sum,money;
            Console.Write("enter degree:");
            degree = Int32.Parse(Console.ReadLine());
            Console.Write("enter month:");
            month = Convert.ToInt32(Console.ReadLine());
            if (month >= 6 && month < 10)
            {
                switch (degree)
                {
                    case degree < 110:  //好像不能直接case < 110
                        money = 2.1;      顯示為無效的運算式
                        break;
                    case degree > 110 && degree <= 330:
                        money = 2.73;
                        break;
                    case degree > 330 && degree <= 500:
                        money = 3.31;
                    default:
                        money = 3.465;  //每行都為無法將bool隱涵轉換int
                        break;            可是我沒有宣告bool型別阿??
                                          而且依開始我也將degree轉型了.....


又要再次麻煩各位了.....感激不盡...
                }
            }
            else
            {
                switch (degree)
                {
                    case degree <= 110:
                        money = 2.1;
                        break;
                    case degree > 110 && degree <= 330:
                        money = 2.413;
                        break;
                    case degree > 330 && degree <= 500:
                        money = 2.73;
                    default:
                        money = 2.73;
                        break;
                }
            }
            sum = degree * money;
            Console.Write("電費為:{0}", sum);
            Console.ReadLine();

推 kojiro1982:degree < 110這一個敘述是boolean值
→ kojiro1982:不是true 就是false
→ kojiro1982:而degree是int 所以會發生錯誤
→ kojiro1982:這個程式不適合用switch case
→ kojiro1982:還是用 if...else if...else if......else 來寫吧
