用enum value作為array index in C#

為了免code看不懂，可以用enum去指定array的index
ex:
cars[0] = .....
-> cars[(int)carNames.MrsOliver] = ....
 好處是在遙遠的另一邊不用去猜0號車到底是MrsOliver還是MrsMarry

範例:

Schedule[] schedules = new int[Enum.GetNames(typeof(WeekDay)).Length];

enum WeekDay
{
    sun = 0;
    mon = 1;
    tue = 2;
 ...
}

schedules[(int)weekDay.sun] = ....

當然也可以建立個key是enum type的 dictionary
Dictionary<WeekDay, Schedule> schedules = new Dictionary<WeekDay, Schedule>();

就可以直接存取
schedules[weekDay.sun] = ....
