C#窗体程序石头剪刀布比赛，三局两胜，代码

在C#中创建一个简单的窗体应用程序来进行石头剪刀布游戏，涉及的主要步骤包括界面设计、用户输入处理和判断游戏结果。这里提供一个简化版的示例代码：

using System;
using System.Windows.Forms;

public partial class MainForm : Form
{
    private Random random = new Random();
    public enum Choices { Rock, Paper, Scissors }

    public MainForm()
    {
        InitializeComponent();

        StartGame();
    }

    private void StartGame()
    {
        for (int i = 0; i < 2; i++)
        {
            ShowPlayerChoice();
            ShowComputerChoice();
            DisplayResult();
            MessageBox.Show($"Round {i + 1} - Player wins!" if JudgeGame() else "Round {i + 1} - Computer wins!");
            ClearInputs();
        }
        DetermineWinner();
    }

    // 用户输入
    private void buttonRock_Click(object sender, EventArgs e)
    {
        textBoxPlayerChoice.Text = "Rock";
    }

    // 计算机随机选择
    private void ChooseRandom()
    {
        Choices compChoice = (Choices)random.Next(0, 3);
        pictureBoxCompChoice.Image = GetImageForChoice(compChoice);
    }

    // 判断游戏结果
    private bool JudgeGame()
    {
        Choices playerChoice = ConvertToEnum(textBoxPlayerChoice.Text);
        return Compare(playerChoice, pictureBoxCompChoice.Tag as Choices);
    }

    // 渲染玩家选择并显示结果
    private void ShowPlayerChoice()
    {
        // 石头、纸、剪刀图片的设置...
        pictureBoxPlayerChoice.Image = GetImageForChoice(playerChoice);
    }

    private void ShowComputerChoice()
    {
        ChooseRandom();
    }

    // 渲染电脑的选择并隐藏
    private void DisplayResult()
    {
        pictureBoxCompChoice.Visible = false;
    }

    // 游戏结束后的操作
    private void DetermineWinner()
    {
        if (winCount == 2)
            MessageBox.Show("Player wins the game!");
        else if (loseCount == 2)
            MessageBox.Show("Computer wins the game!");
        else
            MessageBox.Show("It's a tie!");

        Close();
    }

    // 其他辅助方法

    private Choices ConvertToEnum(string text)
    {
        // 根据字符串转换为enum值...
    }

    private Image GetImageForChoice(Choices choice)
    {
        // 获取对应图片对象...
    }

    private bool Compare(Choices a, Choices b)
    {
        // 判断游戏规则...
    }

    private int winCount = 0, loseCount = 0;
    private void ClearInputs()
    {
        textBoxPlayerChoice.Text = "";
        pictureBoxPlayerChoice.Image = null;
        pictureBoxCompChoice.Visible = true;
    }
}

这个示例仅包含了基本的游戏框架，实际项目中还需要添加更多的错误检查、用户界面美化以及更细致的游戏规则判断。记住，这只是一个简化的版本，完整的代码会更复杂，需要包含更多细节和异常处理。
