我可以做出switch語句來詢問布爾值是否等於true嗎？

Question

我正在寫一個Tic Tac Toe游戲，想要檢查是否單擊了以下按鈕。 （如果為true，則表示您已經贏了。）我認為switch語句對此更有效，但是紅色標記了下划線，我不明白為什么。

這是我當前的代碼：

    using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

namespace Tic_tac_toe2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        bool buttonisclicked = false;
        bool buttonisclicked1 = false;
        bool buttonisclicked2 = false;
        bool buttonisclicked3 = false;

        public void button1_Click(object sender, EventArgs e)
        {
            Button clickedButton1 = (Button)sender;
            clickedButton1.Text = "X";

            if (clickedButton1.Text == "X")
            {

                buttonisclicked1 = true;
            }
        }

        public void button2_Click(object sender, EventArgs e)
        {
            Button clickedButton2 = (Button)sender;
            clickedButton2.Text = "X";

            if (clickedButton2.Text == "X")
            {

                buttonisclicked2 = true;
            }
        }

        public void button3_Click(object sender, EventArgs e)
        {
            Button clickedButton3 = (Button)sender;
            clickedButton3.Text = "X";

            if (clickedButton3.Text == "X")
            {

                buttonisclicked3 = true;
            }
        }

        private void button4_Click(object sender, EventArgs e)
        {
            Button clickedButton = (Button)sender;
            clickedButton.Text = "X";

            if (clickedButton.Text == "X")
            {

                buttonisclicked = true;
            }
        }

        private void button5_Click(object sender, EventArgs e)
        {
            Button clickedButton = (Button)sender;
            clickedButton.Text = "X";

            if (clickedButton.Text == "X")
            {

                buttonisclicked = true;
            }
        }

        private void button6_Click(object sender, EventArgs e)
        {
            Button clickedButton = (Button)sender;
            clickedButton.Text = "X";

            if (clickedButton.Text == "X")
            {

                buttonisclicked = true;
            }
        }

        private void button7_Click(object sender, EventArgs e)
        {
            Button clickedButton = (Button)sender;
            clickedButton.Text = "X";

            if (clickedButton.Text == "X")
            {

                buttonisclicked = true;
            }
        }

        private void button8_Click(object sender, EventArgs e)
        {
            Button clickedButton = (Button)sender;
            clickedButton.Text = "X";

            if (clickedButton.Text == "X")
            {

                buttonisclicked = true;
            }
        }

        private void button9_Click(object sender, EventArgs e)
        {
            Button clickedButton = (Button)sender;
            clickedButton.Text = "X";

            if (clickedButton.Text == "X")
            {

                buttonisclicked = true;
            }

            void Win()
            {
                switch (buttonisclicked)
                {
                    case bool buttonisclicked1 && buttonisclicked2 && buttonisclicked3 = true:

                        Console.WriteLine("Won");
                        break;
                }


            }
        }

我必須擺脫休息嗎？ 還是不能使用&&運算符？

Answer 1

老實說，我喜歡您要嘗試執行的操作，但是對於布爾值（只能為true或false）這樣的簡單操作，僅需要if語句 ：

if (buttonisclicked1 && buttonisclicked2 && buttonisclicked3) {
    Console.WriteLine("Won");
}

如果希望返回的結果為false，則只需添加到前面的代碼中即可：

else {
    Console.WriteLine("Lost"); // <-- Replace this with whatever you want
}

祝您項目順利！ 希望這會有所幫助。

在做a腳趾游戲時，最好將記分邏輯與事件分開。

您應該在表單中創建此變量：

    private Button[][] _buttons = null;

然后在Form_Load執行以下操作：

        _buttons = new []
        {
            new [] { button1, button2, button3 },
            new [] { button4, button5, button6 },
            new [] { button7, button8, button9 },
        };

現在，您可以創建一個方法，該方法返回一個字符串列表，該字符串在水平，垂直和對角線上對網格進行切片：

    private IEnumerable<string> GetSlices() =>
        Enumerable
            .Range(0, 3)
            .SelectMany(n => new[]
            {
                String.Join("", Enumerable.Range(0, 3).Select(m => _buttons[m][n].Text)),
                String.Join("", Enumerable.Range(0, 3).Select(m => _buttons[n][m].Text))
            })
            .Concat(new[]
            {
                String.Join("", Enumerable.Range(0, 3).Select(x => _buttons[x][x].Text)),
                String.Join("", Enumerable.Range(0, 3).Select(x => _buttons[x][2 - x].Text))
            });

然后，每當您更新按鈕上的文本時，您都可以算出誰贏了，就像這樣：

        var slices = GetSlices();

        if (slices.Any(s => s == "XXX"))
        {
            MessageBox.Show("X Won!");
        }

        if (slices.Any(s => s == "OOO"))
        {
            MessageBox.Show("O Won!");
        }
