C＃在涉及字符串的參數傳遞時感到困惑

Question

真的很困惑這個家庭作業，我不是在尋找答案，而是一些指導。我很困惑我將如何接受用戶輸入，並通過它來從數組中取出這些響應中的一個，具體取決於它們的輸入是1到5.下面是問題。

創建一個名爲Magic8Ball（控制檯或GUI，您的選擇）的程序。該程序應該包含一個方法（由您編寫），用至少五個字符串聲明一個Magic 8-Ball類型短語的數組，例如「答案似乎確定」（您可以編寫短語或使用傳統的方法 - 谷歌魔法8ball短語來查看它們，你的方法應該接受一個參數，這個參數是短語字符串數組的一個索引，你的方法將顯示與傳入方法的索引相關的短語，例如，如果短語[4]中的字符串是「未來看起來陰天」和調用程序傳遞的值4到你的方法，則該方法將顯示「未來顯得渾濁。」包括錯誤處理在你的方法，所以只有有效的索引將產生輸出。

namespace ConsoleApp7 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      int response; 

      string[] quotes; 
      quotes = new string[5]; 

      { 
       quotes[1] = ("Today is going to be a good day"); 
       quotes[2] = ("Tomorrow is going to rain"); 
       quotes[3] = ("Next month will be blissful"); 
       quotes[4] = ("You are very lucky to be here"); 
       quotes[5] = ("The love of your life notices you"); 
      }; 

      WriteLine("Please enter a number between one and five"); 

      response = Convert.ToInt32(ReadLine()); 

      if (response = quotes[1]) 
      { 

      } 
     } 
    } 
}

namespace ConsoleApp7 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      int response; 

      string[] quotes = new string [5]; 


      { 
       quotes[0] = ("Today is going to be a good day"); 
       quotes[1] = ("Tomorrow is going to rain"); 
       quotes[2] = ("Next month will be blissful"); 
       quotes[3] = ("You are very lucky to be here"); 
       quotes[4] = ("The love of your life notices you"); 
      } 

      WriteLine("Please enter a number between one and five"); 

      response = Convert.ToInt32(ReadLine()); 


      WriteLine(quotes[response]);

response是從1到5的數字。要獲得與響應對應的數組項（字符串引號），您需要評估quote[response-1]。這是因爲在C#中陣列是基於0的。這意味着5個項目的數組索引爲0..4。

class Program 
{ 
    static void Main(string[] args) 
    { 
     string[] quotes = new string[] 
     { 
      "Today is going to be a good day", 
      "Tomorrow is going to rain", 
      "Next month will be blissful", 
      "You are very lucky to be here", 
      "The love of your life notices you" 
     }; 

     int response; 
     int.TryParse(Console.ReadLine(), out response); 
     if (response>=1&&response<=quotes.Length) 
     { 
      Console.WriteLine(quotes[response-1]); 
     } 
     else 
     { 
      Console.WriteLine("Invalid input"); 
     } 
    } 
} 

順便說一句，這個問題與傳遞參數無關。
