如何捕获与枚举参数不匹配的输入

Question

我这里有一种输入星期几的方法，但是如果我输入的数字值不是1到7，则程序会简单地得出结论。我想有一种方法来触发捕获。        namespace DaysOfTheWeek{class Program{    public enum EDay    {        Monday,        Tuesday,        Wednesday,        Thursday,        Friday,        Saturday,        Sunday,    }    static void Main(string[] args)    {        try        {            Console.WriteLine("Hello!  A week has 7 days!  What day of this week is it?");            EDay pickDay = (EDay)Enum.Parse(typeof(EDay), Console.ReadLine(), true);            Console.WriteLine("The day you picked was {0}", pickDay - 1);            Console.ReadLine();        }        catch (Exception)        {          Console.WriteLine("Please enter an actual numerical day of the week.");            Console.ReadLine();        }    }}}
