我想将列表中的数字传递给 Player 类并打印它们，但是当我尝试编译它时给我一个例外。我的错误在哪里？

        }
    }


    public class Shuffle : Poker
    {
        public static List<int> numbers = new List<int>();
        Random random = new Random();

        public Shuffle()

                }

            Console.WriteLine(cardThree);
            Console.WriteLine(cardFour);
        }

}

当崩溃发生时，它说： 当崩溃发生时，它说： 当崩溃发生时，它说：

您有一个接受两个整数的方法，并且您尝试在不传递任何参数的情况下调用它：

public static void playerOne(int cardOne, int cardTwo)

但是你这样称呼它：

cards.playerOne();

你需要通读你的代码，看看它是如何工作的，也许阅读一些关于 C# 基础的文章？

我明白你想做什么。您想在方法中使用内部变量，但在方法的参数中包含它们。

public static void playerOne(int cardOne, int cardTwo)
{
    Console.WriteLine(cardOne);
    Console.WriteLine(cardTwo);
}

应该：

public static void playerOne()
{
    Console.WriteLine(cardOne);
    Console.WriteLine(cardTwo);
}
