我目前正在为我的课程项目制作一个Rythm游戏，我在实现BGM开/关按钮时遇到了麻烦。
下面是我的简化代码：

• • 表格一**

public partial class Form1 : Form
    {
    public SplashScreen()
        {
            InitializeComponent();
            
            string path= System.Reflection.Assembly.GetEntryAssembly().Location;
            axWindowsMediaPlayer1.settings.volume = 0;
            axWindowsMediaPlayer1.Ctlcontrols.stop();
            axWindowsMediaPlayer1.URL = path.Remove(path.Length - 44) + "\\assets\\main.wav";
        }
        
        
        void BGMoff()
        {
            axWindowsMediaPlayer1.settings.mute = true;
        }
        void BGMon()
        {
            axWindowsMediaPlayer1.settings.mute = false;
        }
        
        
        private void Form1_Load(object sender, EventArgs e)
        {
            Form2 main = new Form2();
            main.BGM_off += BGMoff;
            main.BGM_on += BGMon;
        }
    }

• • 表格二**

public partial class Form2 : Form
        
    {
        public delegate void ClickButton();
        public event ClickButton BGM_off;
        public event ClickButton BGM_on;
        
        bool BGM = true
        
        public void button4_Click_1(object sender, EventArgs e)
        {
            if (BGM)
            {
                button4.BackgroundImage = Properties.Resources.BGMoff;
                BGM = false;
                BGM_off?.Invoke();
            }
            else
            {
                button4.BackgroundImage = Properties.Resources.BGMon;
                BGM = true;
                BGM_on?.Invoke();

            }
        }
    }

这是根据Darin对this thread的评论做出的。我相信我正确地按照步骤访问了axWindowsMediaPlayer，但是我错了。
