我需要让剪刀赢得纸张，摇滚胜利剪刀等等。我目前有声明userChoice！= computerChoice但这不会起作用，因为摇滚会赢得纸张。我不知道如何做这项工作，我已经尝试过思考，目前无法思考任何事情，我只是一个初学程序员。

    const int ROCK = 1;
    const int PAPER = 2;
    const int SCISSORS = 3;

    private void rockButton_Click(object sender, EventArgs e)
    {
        int userChoice = ROCK;
        userPictureBox.Image = Properties.Resources.Rock;

        Random randomNumberGenerator = new Random();
        int computerChoice = randomNumberGenerator.Next(1, 4);
        switch (computerChoice)
        {
            case ROCK:
                computerPictureBox.Image = Properties.Resources.Rock;
                break;

            case PAPER:
                computerPictureBox.Image = Properties.Resources.Paper;
                break;

            case SCISSORS:
                computerPictureBox.Image = Properties.Resources.Scissors;
                break;
        }

        if (userChoice == computerChoice)
            MessageBox.Show("It's a tie.");

        else if (userChoice != computerChoice)
        {
            MessageBox.Show("You win!");
        }

    }

    private void paperButton_Click(object sender, EventArgs e)
    {
        int userChoice = PAPER;
        userPictureBox.Image = Properties.Resources.Paper;

        Random randomNumberGenerator = new Random();
        int computerChoice = randomNumberGenerator.Next(1, 4);
        switch (computerChoice)
        {
            case ROCK:
                computerPictureBox.Image = Properties.Resources.Rock;
                break;

            case PAPER:
                computerPictureBox.Image = Properties.Resources.Paper;
                break;

            case SCISSORS:
                computerPictureBox.Image = Properties.Resources.Scissors;
                break;

        }
        if (userChoice == computerChoice)
            MessageBox.Show("It's a tie.");

        else if (userChoice != computerChoice)
        {
            MessageBox.Show("You win!");
        }
    }

    private void scissorsButton_Click(object sender, EventArgs e)
    {
        int userChoice = SCISSORS;
        userPictureBox.Image = Properties.Resources.Scissors;

        Random randomNumberGenerator = new Random();
        int computerChoice = randomNumberGenerator.Next(1, 4);
        switch (computerChoice)
        {
            case ROCK:
                computerPictureBox.Image = Properties.Resources.Rock;
                break;

            case PAPER:
                computerPictureBox.Image = Properties.Resources.Paper;
                break;

            case SCISSORS:
                computerPictureBox.Image = Properties.Resources.Scissors;
                break;

        }
        if (userChoice == computerChoice)
            MessageBox.Show("It's a tie.");

        else if (userChoice != computerChoice)
        {
            MessageBox.Show("You win!");

Answer 1

创建矩阵dict，其中行 - 人类选择，列 - 计算机选择和dict[i,j] - 结果，胜者：人或计算机。

var dict = new Dictionary<int, Dictionary<int, string>>();
dict[ROCK] = new Dictionary<int, string> { { ROCK , "draw"}, {PAPER, "computer"}, {SCISSORS , "human"} };
dict[PAPER] = new Dictionary<int, string> { { ROCK , "human" }, { PAPER, "draw" }, { SCISSORS, "computer" } };
dict[SCISSORS] = new Dictionary<int, string> { { ROCK , "computer" }, { PAPER , "human" }, { SCISSORS , "draw" } };
var winner = dict[userChoice, computerChoice];

Answer 2

if(userChoice == 1 && computerChoice == 2)
{
MessageBox.Show("You win!")
}
else if(userChoice == 2 && computerChoice == 3)
{
MessageBox.Show("You lose!")
}
else if(userChoice == 3 && computerChoice == 1)
{
MessageBox.Show("You lose!")
}

因为你有摇滚，纸和剪刀的价值。

我的同事告诉我这个，看起来很基本但有逻辑。注意：只需添加其他案例。
