                    ans2.Text = "bhfsfs";

如果button1是播放按钮，那么我猜你的while（）循环错了。

它永远不会输入while(questionNr >= 2)，因为在创建实例时，questionNr为1。

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

    public Form1() { ... }
}

变化：

        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";
            }
        }

要：

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

触发事件时Text属性不会更改
