c# 如何在函数中使用实例化的对象属性(这是一个列表)？

Question

我有两个类(class)。具有 Name、Balance 和 Cards 属性的玩家类:

class Player
{
    public string Name;
    public decimal Balance;
    public List<Card> Cards; // My question is related to this property
}

还有一个 Card 类:

class Card
{
    public string Name;
    public int Attack;
    public int Defense;
    public decimal Cost;
}

我为玩家实例化了一个对象:

var player = new Player("Ahmad", 100);

还有一张卡片:

var card = new Card("Mino", 3, 3, 200);

然后将卡片添加到玩家的卡片中:

player.Cards[0] = card;

我可以简单地在实例化它的主要方法上显示它，但问题是:如何在函数中访问玩家的卡片？像这样:

///<summary>
/// Function to show current cards
/// </summary>
public static void ViewCards(object player)
{
    var cards = player.Cards  // This line doesn't work
    foreach (var card in cards)
    {
        Console.WriteLine($"{card.Name}");
        Console.WriteLine($"Attack: {card.Attack}");
        Console.WriteLine($"Defense: {card.Defense}");
        Console.WriteLine($"Cost: ${card.Cost}");
    }    
}

Answer 1

更改方法签名更改播放器参数，从 Object 到 Player

public static void ViewCards(Player player)
{
}
