【问题描述】：
为了优化代码，我需要用方法替换 switch 构造，但结果相同。我已经尝试了很长时间，但我做不到。如果您能提供帮助，我将不胜感激！这是我的老师写给我的：“Katrin 在 switch 中，你传递一个值和一个整数。在最简单的情况下可以将其视为数组索引。在更复杂的情况下，可以将其视为通用表达式的元素此值的不同结果。如果您可以编写一个与 switch-case 给出相同结果的函数，那么记录将是紧凑的（好像它由单个 case 块组成），因此不需要 switch-case"

string[] array2 = new string[44]{(44 elements)};//Array of qualities: HEALTH status

string[] array4 = new string[40] {(40 elements)};//Array of qualities : a HOBBY.
string[] array5 = new string[41] {(41 elements)};//Array of qualities : PHOBIAS.
string[] array6 = new string[50] {(50 elements)};//Array of Luggage.
string[] array8 = new string[39] {(39 elements)};//An array of player's cards.
string[] array7 = new string[50] {(50 elements)};//Array of Additional information.
