如何檢查用戶是否正確輸入命令 - C＃

Question

我正在爲C＃的控制檯應用程序中的冒險類文本遊戲工作。

我需要一種方法來測試用戶是否正確地輸入命令，並且他們是否不再測試。

我現在嘗試這一權利：

do 
{ 
    Response = Console.ReadLine(); 
    switch (Response.ToLower()) 
    { 
     case "hallway": 
      Location = Locations[2]; 
      Console.WriteLine("You decide to get some fresh air, and step out of the dance room and into the hallway." + "\n" + "There's no one here."); 
      Console.ForegroundColor = ConsoleColor.Cyan; 
      Console.WriteLine("Command List: Look, Look at, Move, Check Status"); 
      Console.ResetColor(); 
      ResponseTester(); 
      break; 
     case "dance room": 
      //[Other code here] 
      break; 
     default: 
      Console.WriteLine("I'm sorry, I don't understand that."); 
      break; 
    } 
} 
while (Response.ToLower() != "hallway" || Response.ToLower() != "dance room"); 

但是它不是很可靠的，因爲當我嘗試它與if/else語句或其他用途，這將只測試一次。有沒有更好的方法來測試？

你需要如下

var invalid = true; 
while (invalid) 
{ 
    Response = Console.ReadLine(); 
    switch (Response.ToLower()) 
    { 
     case "hallway": 
     Location = Locations[2]; 
     Console.WriteLine("You decide to get some fresh air, and step out of the dance room and into the hallway." + "\n" + "There's no one here."); 
     Console.ForegroundColor = ConsoleColor.Cyan; 
     Console.WriteLine("Command List: Look, Look at, Move, Check Status"); 
     Console.ResetColor(); 
     ResponseTester(); 
     invalid = false; 
     break; 
    case "dance room": 
     //[Other code here] 
     invalid = false; 
     break; 
    default: 
     Console.WriteLine("I'm sorry, I don't understand that."); 
     break; 
    } 
    } 

但除此之外，真正獲取輸入需要從處理輸入的遊戲設計單獨重寫一遍。設置一個數組或可接受的單詞列表，然後對其進行測試，然後分別進行處理。所以像這樣的

private List<string> validWords = new List<string>{"hallway","dance room"}; 

private string GetInput() 
{ 
    var response = string.Empty; 
    while (true) 
    { 
     response = Console.ReadLine(); 
     if (validWords.Contains(response)) 
     { 
      break; 
     } 
    } 
    return response; 
} 

private void ProcessInput(string response) 
{ 
    //switch statements go here 
}
