我知道互聯網上有很多食譜，但我想自己掌握。使用簡單的方法，我只想訪問數組并獲取“WORD”即 = 用戶輸入的數字例如輸入33三十三所以我必須將 33 除以 10獲取第一個數字并乘以 10得到余數得到“三十”從十數組和“樹”從單位如何將信息與數組進行比較并獲取重要信息？ 對于循環？int number;int i = 0;String[] units = new String[] { "one", "two", "three" };String[] tens = new String[] { "twenty", "thirty", "forty" };Console.WriteLine("Please enter a number");number = Convert.ToInt32(Console.ReadLine());if (number < 20){ Console.WriteLine("The number is"); Console.WriteLine(units[]);}else if (number > 20){ Console.WriteLine("The number is"); Console.WriteLine(tens[]);}

您可以毫不費力地將其擴展到 1000 以上。 我相信在這里使用字典而不是列表要好得多。它速度快，而且您犯錯誤的可能性較小。
