Question

我刚刚完成了Head First C＃的练习，在那里我建立了一个打字游戏。这本书让读者知道如何制作它，以便玩家可以在失去后开始新游戏。在用户输掉游戏后，窗口显示消息“游戏结束”。我想弹出一个新窗口，询问用户是否希望在屏幕上关闭游戏后再次播放。我希望有两个按钮;一个说“不”，一个说“是”。我坚持的是如果用户决定再次玩游戏，我应该（或将会）重新启动应用程序。我将复制并粘贴下面的代码：

namespace _7HeadFirstProject
{
    public partial class Form1 : Form
    { 
        Random random = new Random();
        Stats stats = new Stats();

        public Form1()
        {
            InitializeComponent();
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            // Add a random key to the ListBox
            listBox1.Items.Add((Keys)random.Next(65, 90));
            if (listBox1.Items.Count > 7)
            {
                listBox1.Items.Clear();
                listBox1.Items.Add("Game Over");
                timer1.Stop();
            }
        }

        private void Form1_KeyDown(object sender, KeyEventArgs e)
        {
            // If the user pressed a key that's in the ListBox... 
            // ... remove it and then make the game a little faster
            if (listBox1.Items.Contains(e.KeyCode))
            {
                listBox1.Items.Remove(e.KeyCode);
                listBox1.Refresh();
                if (timer1.Interval > 400)
                    timer1.Interval -= 10;
                if (timer1.Interval > 250)
                    timer1.Interval -= 7;
                if (timer1.Interval > 100)
                    timer1.Interval -= 2;
                difficultyProgressBar.Value = 800 - timer1.Interval;

                // The user pressed a correct key, so update the Stats object...
                // ...by calling its Update() method with the argument true
                stats.Update(true);
            }
            else
            {
                // The user pressed an incorrect key, so update the Stats object...
                // ...by calling its Update() method with the argument false
                stats.Update(false);
            }

            // Update the labels on the StatusStrip
            correctLabel.Text = "Correct: " + stats.Correct;
            missedLabel.Text = "Missed: " + stats.Missed;
            totalLabel.Text = "Total: " + stats.Total;
            accuracyLabel.Text = "Accuracy: " + stats.Accuracy + "%";
        }

        private void Form1_FormClosed(object sender, FormClosedEventArgs e)
        {
            MessageBox.Show("Would you like to play again?");
            if

        }
    }
}

不同类：

namespace _7HeadFirstProject
{
    class Stats
    {
        public int Total = 0;
        public int Missed = 0;
        public int Correct = 0;
        public int Accuracy = 0;

        public void Update(bool correctKey)
        {
            Total++;

            if (!correctKey)
            {
                Missed++;
            }
            else
            {
                Correct++;
            }

            Accuracy = 100 * Correct / Total;
        }
    }
}

Answer 1

试试这个：

   if ((MessageBox.Show("Would you like to play again?", "Message", MessageBoxButtons.YesNo)) ==
                DialogResult.Yes)
  { 
     Application.Restart();
  }

你让整个游戏都有效，所以单独保留这种形式。将另一个表单添加到项目中，然后将新表单设置为启动表单。您可以通过打开Program.cs并修改此行来将其设置为启动表单：

 // Instead of Form1 put the name of your new form
Application.Run(new Form1());

双击新表单并将此代码放入其中：

// Note: Your load method may have a different name.
private void Form2_Load(object sender, EventArgs e)
{
    this.StartNewGame();
}

private void GameForm_FormClosed(object sender, FormClosedEventArgs e)
{
    if (MessageBox.Show("Continue?", "Continue?", MessageBoxButtons.YesNo) == DialogResult.Yes)
    {
        this.StartNewGame();
    }
}

private void StartNewGame()
{
    // Your game form may have a different name so change this to that name
    var gameForm = new Form2();
    gameForm.FormClosed += GameForm_FormClosed;
    gameForm.Show();
}

每次用户按下对话框上的“是”按钮，您就会创建一个全新的表格实例（游戏）。在这个新形式中，您还可以使用一个数组来跟踪游戏总数以及每个游戏的分数，以便您可以在用户选择的情况下显示它。所有您需要的是这样的：

var games = new List<Stats>();
// keep adding to it every time you call StartNewGame() method.
