事件觸發時文本屬性不會改變

Question

我正在c＃中快速測驗遊戲，並且在播放時我正在努力使標籤（questionLabel）和按鈕（ans1 - ans4）顯示指定的文本按鈕已被點擊，預先感謝您。

namespace WindowsFormsApplication1 
{ 
     public partial class Form1 : Form 
{ 
    int pointCounter = 0; 
    private SoundPlayer _soundPlayer; 
    int questionNr = 1; 

    public Form1() 
    { 
     InitializeComponent(); 
     _soundPlayer = new SoundPlayer("song.wav"); 
    } 

    private void pictureBox1_Click(object sender, EventArgs e) 
    { 
     System.Diagnostics.Process.Start("http://rads.stackoverflow.com/amzn/click/B007AFS0N2"); 
    } 

    private void Form1_Load(object sender, EventArgs e) 
    { 
     _soundPlayer.PlayLooping(); 
    } 


    private void label1_Click(object sender, EventArgs e) 
    { 

    } 

    private void muteButton_Click(object sender, EventArgs e) 
    { 
     if (muteButton.Text == "Mute") 
     { 

      muteButton.Text = "Unmute"; 
      _soundPlayer.Stop(); 
     } 

     else 
     { 
      muteButton.Text = "Mute"; 
      _soundPlayer.PlayLooping(); 
     } 



    } 

    private void button1_Click(object sender, EventArgs e) 
    { 
      ans1.Visible = true; 
      ans2.Visible = true; 
      ans3.Visible = true; 
      ans4.Visible = true; 
      playButton.Visible = false; 

     while (questionNr >= 2) 
      { 
       if (questionNr == 1) 
       { 
        questionLabel.Text = "What is Chuck's full name?"; 
        ans1.Text = "fushfus"; 
        ans2.Text = "bhfsfs"; 
        ans3.Text = "Chuck"; 
        ans4.Text = "sfhus"; 
       } 
      } 
    } 

    private void ans3_Click(object sender, EventArgs e) 
    { 
     if (questionLabel.Text == "What is Chuck's full name?") 
     { 
      pointCounter++; 
     } 
     else 
     { 

     } 
    } 
     public void PointCounter(){ 
      pointsLabel.Text = pointCounter.ToString(); 
    } 
    } 
}

如果button1是播放按鈕，那麼我想你錯了while（）循環。

它將永遠不會輸入while(questionNr >= 2)，因爲當您創建實例時questionNr爲1。

public partial class Form1 : Form 
{ 
    int pointCounter = 0; 
    private SoundPlayer _soundPlayer; 
    int questionNr = 1; <-- 

    public Form1() { ... } 
} 

變化：

 while (questionNr >= 2) 
     { 
      if (questionNr == 1) 
      { 
       questionLabel.Text = "What is Chuck's full name?"; 
       ans1.Text = "fushfus"; 
       ans2.Text = "bhfsfs"; 
       ans3.Text = "Chuck"; 
       ans4.Text = "sfhus"; 
      } 
     } 

到：

  if (questionNr == 1) 
      { 
       questionLabel.Text = "What is Chuck's full name?"; 
       ans1.Text = "fushfus"; 
       ans2.Text = "bhfsfs"; 
       ans3.Text = "Chuck"; 
       ans4.Text = "sfhus"; 
      }
