無過載方法「命中」需要1個參數。需要返回兩個列表

Question

我在調用main函數時遇到了麻煩，因爲它需要同時返回2個列表。該功能將卡從一個列表添加到另一個列表，然後將其從原始列表中刪除。但是，當我嘗試並調用我得到這個錯誤的函數...沒有重載方法「命中」需要1個參數

using System; 
    using System.Collections.Generic; 
    using System.Text; 

    namespace BlackJackGameX 
    { 
     public class MainClass 
     { 
      public static void Main (string[] args) 
      { 

       Deck Cards = new Deck(); 

       Hand PlayerHand = new Hand(); 

       Console.WriteLine("Welcome to Black Jack\n\nPress Enter To Start"); 
       Console.ReadLine(); 

       PlayerHand.Hit(PlayerHand); 
       PlayerHand.Hit(PlayerHand); 
       PlayerHand.HandPrint(); 


      } 
     } 
    } 

的問題是在這手牌類的命中功能底部

using System; 
using System.Collections.Generic; 
using System.Text; 

namespace BlackJackGameX 
{ 
    public class Hand 
    { 

     Deck CardDeck = new Deck(); 

     public List<Card> PlayerHand; 

     public Hand() 
     { 

     } 

     public void HandPrint() 
     { 
      for (int i = 0; i < PlayerHand.Count; ++i) 
      { 
       Console.WriteLine("You have a " + PlayerHand[i].CardValue + " of " + PlayerHand[i].CardSuit); 

       if (i < PlayerHand.Count) 
       { 
        Console.WriteLine ("&"); 
       } 
      } 

      Console.ReadLine(); 

     } 

     public List<Card> Hit(List<Card> CardDeck, List<Card> PlayerHand) 
     { 
      PlayerHand.Add(CardDeck[1]); 
      CardDeck.Remove(CardDeck[1]); 

      return PlayerHand; 
     } 

    } 
} 

Answer 1

您遇到的錯誤是因爲Hand類中的Hit()方法接受2個參數，而不是1.它期望兩個參數List<Card>()。

您的代碼傳遞的是Hand對象，根本無法工作，無論參數的數量如何。

Answer 2

您的Hit方法預計有兩個List<Card>參數，但只傳遞一個Hand對象。

public List<Card> Hit(List<Card> CardDeck, List<Card> PlayerHand) 
{ 
    ... 
} 

你需要做的是通過Cards對象主要爲Hand構造使手可以使用它什麼：

public class Hand 
{ 
    // You should make this private with a public property to guard it 
    public List<Card> PlayerHand; 

    // No reason to expose this to the outside 
    private Deck cardDeck = new Deck(); 

    public Hand (Deck cards) 
    { 
     cardDeck = cards; 
    } 

    // There's nothing worth returning here, so make it void 
    public void Hit() 
    { 
     // I would probably implement a method in the Deck class 
     // so you could do something like (where RemoveNext returns the card removed): 
     // playerHand.Add(cards.RemoveNext()); 
     playerHand.Add(CardDeck[1]); 
     CardDeck.Remove(CardDeck[1]); 
    } 

而且你Main看起來是這樣的：

public static void Main (string[] args) 
{ 
    Deck cards = new Deck(); 
    Hand playerHand = new Hand(cards); 

    Console.WriteLine("Welcome to Black Jack\n\nPress Enter To Start"); 
    Console.ReadLine(); 

    playerHand.Hit(); 
    playerHand.Hit(); 
    // I would rename this to PrintHand(). HandPrint is a noun. 
    playerHand.HandPrint(); 
}
