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的时候给我一个例子。我的错误在哪里？

        Random random = new Random();

        public Shuffle()

            {
                int number = random.Next(1, 53);
                if (!numbers.Contains(number))
                {

        }

    public class Player : Shuffle
    {

        private static int cardOne = numbers[0];
        private static int cardTwo = numbers[1];

Answer 1

你有一个接受两个整数的方法，你试图在不传递任何参数的情况下调用它：

public static void playerOne(int cardOne, int cardTwo)

但你这样称呼它：

cards.playerOne();

您需要仔细阅读代码并了解它的工作原理，或者阅读一些C＃基础知识的文章？

我明白你要做什么。您希望在方法中使用内部变量，但是您可以在方法的参数中使用它们。

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

应该是：

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

调用方法时出现未处理的异常
