c# - 没有对 'card' 的隐式引用从 'card' 到 IComparable 的转换

Question

如何比较卡列表？我收到此错误，但我不知道这意味着什么或如何修复它。我得到的错误:

the type 'Card' cannot be used as type parameter 'T' in generic type or method 'secondClass'. there is no implicit reference to 'Card' convertion from 'Card' to 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 类需要实现IComparable 接口(interface)
