調用方法時出現未處理的異常

Question

我想將列表中的數字傳遞給Player類並將其打印出來，但是當我嘗試編譯它時，我將它拖到了外面。我的錯誤在哪裏？

     } 
    } 


    public class Shuffle : Poker 
    { 
     public static List<int> numbers = new List<int>(); 
     Random random = new Random(); 

     public Shuffle() 
     { 
      for (int runs = 0; runs < 530; runs++) 
      { 
       int number = random.Next(1, 53); 
       if (!numbers.Contains(number)) 
       { 
        numbers.Add(number); 
       } 
      } 
     }

     private static int cardOne = numbers[0]; 
     private static int cardTwo = numbers[1];

Answer 1

你必須接受兩個整數的方法，以及你想叫它不傳遞任何參數：

public static void playerOne(int cardOne, int cardTwo) 

但你這樣稱呼它：

cards.playerOne(); 

你需要通讀你的代碼，看看它是如何工作的，也許閱讀一些C＃基礎知識的文章？

我明白你想要做什麼。你想在方法中使用內部變量，但是你可以在方法的參數中使用它們。

public static void playerOne(int cardOne, int cardTwo) 
{ 
    Console.WriteLine(cardOne); 
    Console.WriteLine(cardTwo); 
} 

應該是：

public static void playerOne() 
{ 
    Console.WriteLine(cardOne); 
    Console.WriteLine(cardTwo); 
}
