如何让菜单循环

Question

我期待让菜单循环，所以当我进入帮助菜单，然后返回到主菜单，它将实际运行。相反，当输入任何内容时它都不响应。退出也无论如何不起作用，因此，我将不胜感激任何帮助。谢谢。

using System; 

namespace MasterMind 
{ 
    class Menu 
    { 
     public void DrawMainMenu() 
     { 
      Console.ForegroundColor = ConsoleColor.Green; 
      Console.WriteLine("    MasterMind's Main Menu"); 
      Console.WriteLine("     1: Play"); 
      Console.WriteLine("     2: Help"); 
      Console.WriteLine("     0: Exit"); 
     } 
     public void DrawHelp() 
     { 
      Console.Clear(); 
      Console.WriteLine("Rules Of MasterMind!"); 
      Console.WriteLine("Mastermind is a game about guessing a 4 digit code. The numbers can range from"); 
      Console.WriteLine("1-4 and any other numbers will be rejected. It will say in the CMD"); 
      Console.WriteLine("prompt whether or not you had any of the number correct or false."); 
      Console.WriteLine("Press any key to go back to the main menu."); 
      Console.ReadKey(); 
      Console.Clear(); 
      DrawMainMenu(); 
      Console.ReadLine(); 
     } 
     public void DrawExit() 
     { 
      Console.Clear(); 
      Console.WriteLine("You are about to exit the game"); 
      Console.WriteLine("Are you sure: Y/N"); 
      string userExit = Console.ReadKey().KeyChar.ToString(); 
      if (userExit == "Y") 
      { 
       Environment.Exit(0); 
      } 
      if (userExit == "N") 
      { 
       DrawMainMenu(); 
       Console.ReadLine(); 
      } 
     } 
    } 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      var menu = new Menu(); 
      menu.DrawMainMenu(); 
      string userInput = Console.ReadKey().KeyChar.ToString(); 
      if (userInput == "1") 
      { 

      } 
      if (userInput == "2") 
      { 
       Console.Clear(); 
       menu.DrawHelp(); 
      } 
      if (userInput == "0") 
      { 
       menu.DrawExit(); 
       Console.ReadLine(); 
      } 
     } 
    } 

}

这样的事情可以让你开始。

注意：您可以通过各种方式对结构和逻辑进行改进....我只给你一个例子，有Environment.Exit(0);它可以在... ...它可以通过在while循环有一个“标志”，这是设置，如果你选择“退出”，然后程序只是自然退出可以避免。
