无法获取shuffle方法来收集列表

我遇到了这个愚蠢的问题，我不知道如何解决，我正在创建一个21点游戏，我有一个带有Deck（）和Shuffle（）方法的卡类，以及一个将分发卡的发牌器类。

shuffle方法是我在这个网站上得到的一个扩展方法，很有趣，但我无法让它从Deck（）方法接收卡片列表。。。

我最初确实使用了一本字典，在整理字典时遇到了麻烦，并在这个网站上寻求帮助他们建议使用一个列表，现在我在这里。

这是卡和经销商类别

Card.cs

public static class Card
{
    private static List<string> deckOfCards = new List<string>();

    private static string[] Suite = new string[4] {"Clubs", "Hearts", "Spades", "Diamonds" };
    private static string[] FaceValue = new string[13] {"Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Jack", "Queen", "King" };

    public static void Deck()
    {
        for (int s = 0; s < 4; s++ )
        {
            string sut = Suite[s];
            for (int fV = 0; fV < 13; fV++)
            {
                string value = FaceValue[fV];
                deckOfCards.Add(sut + value);
            }
        }
        // End of For loop.
        Shuffle(deckOfCards);
    }
    public static void Shuffle<T>(this IList<T> list)
    {
        Random rng = new Random();
        int n = list.Count;
        while (n > 1)
        {
            n--;
            int k = rng.Next(n + 1);
            T value = list[k];
            list[k] = list[n];
            list[n] = value;
        }
    }
}

Dealer.cs

class Dealer
{
    private List<string> randomisedCards = new List<string>();
    public Dealer()
    {
        randomisedCards.Shuffle();
    }

    public string dealCard()
    {
        string randCard = randomisedCards[0];
        randomisedCards.RemoveAt(0);
        return randCard;
    }
}

批评是重点推荐，因为这是你学习的方式，但请记住，我还是一个初学者，根本没有经验。
