没有隐含的引用'卡'从'卡'转换为IComparable

Question

如何比较卡片清单？我收到此错误，我不知道它是什么意思或如何解决它。我得到的错误：

  

类型'Card'不能用作泛型类型或方法'secondClass'中的类型参数'T'。没有隐含的引用“卡”转换从“卡”到IComparable

class Node<T>
{
    public int id;
    public T data;
    public Node<T> next;
}

class GameLinkedList<T> where T : IComparable
{
    private Node<T> head;
    private Node<T> temp;
    private int count = 0;

    public void AddFront(T t)
    {
        count++;
        temp = head;
        Node<T> node = new Node<T>();
        node.data = t;
        node.id = count;
        node.next = temp;
        head = node;
    }
}

class Bundle
{
    //private List<Card> deck1;
    GameLinkedList<Card> deck = new GameLinkedList<Card>();
}

class Card
{     
    private Suit suit;
    private Value value;
    private string cardName;
}

您的Card课程需要实施IComparable界面
