实现方法详解

1. 简单实现方法

方法1: 直接在事件处理器中播放音效

private void ButtonWithEventHandler_Click(object sender, RoutedEventArgs e)
{
    // 创建或使用全局播放器
    var player = new MediaPlayer();
    player.Open(new Uri("sounds/click.wav", UriKind.Relative));
    player.Play();
    
    // 或者使用全局播放器
    _globalClickPlayer.Position = TimeSpan.Zero;
    _globalClickPlayer.Play();
}

方法2: 使用附加行为

<Button Content="使用行为" 
        local:SoundBehavior.ClickSound="{StaticResource ClickSoundPlayer}"/>

2. 高级实现方法

悬停+点击音效组合

<Button Content="悬停+点击音效" 
        local:SoundBehavior.HoverSound="{StaticResource HoverSoundPlayer}"
        local:SoundBehavior.ClickSound="{StaticResource ClickSoundPlayer}"/>

自定义音效

private void CustomSoundButton_Click(object sender, RoutedEventArgs e)
{
    // 创建临时音效播放器
    var player = new MediaPlayer();
    player.Open(new Uri("sounds/special_click.wav", UriKind.Relative));
    player.Play();
    
    // 播放完成后自动释放资源
    player.MediaEnded += (s, args) => player.Close();
}

随机音效

private void RandomSoundButton_Click(object sender, RoutedEventArgs e)
{
    if (_randomSounds.Count == 0) return;
    
    int index = _random.Next(0, _randomSounds.Count);
    var player = _randomSounds[index];
    
    player.Position = TimeSpan.Zero;
    player.Play();
}

3. 使用命令实现

public ICommand PlaySoundCommand { get; }

public MainWindow()
{
    PlaySoundCommand = new RelayCommand(ExecutePlaySound);
}

private void ExecutePlaySound()
{
    PlayGlobalClickSound();
}

// XAML
<Button Content="使用命令" Command="{Binding PlaySoundCommand}"/>

高级功能实现

1. 音效管理

// 全局音效管理器
public static class SoundManager
{
    private static readonly Dictionary<string, MediaPlayer> _sounds = new Dictionary<string, MediaPlayer>();
    private static double _globalVolume = 0.7;
    private static bool _isMuted = false;

    public static void LoadSound(string name, string path, double volume = 1.0)
    {
        if (_sounds.ContainsKey(name)) return;
        
        var player = new MediaPlayer();
        player.Open(new Uri(path, UriKind.Relative));
        player.Volume = volume * _globalVolume;
        _sounds[name] = player;
    }

    public static void PlaySound(string name)
    {
        if (_isMuted || !_sounds.TryGetValue(name, out var player)) return;
        
        player.Position = TimeSpan.Zero;
        player.Play();
    }

    public static void SetGlobalVolume(double volume)
    {
        _globalVolume = volume;
        foreach (var player in _sounds.Values)
        {
            player.Volume = volume;
        }
    }

    public static void SetMute(bool isMuted)
    {
        _isMuted = isMuted;
    }
}

// 使用
SoundManager.LoadSound("click", "sounds/click.wav", 0.7);
SoundManager.PlaySound("click");

2. 3D音效效果

private void PlayPositionalSound(Point position)
{
    // 计算相对于窗口中心的位置
    double centerX = ActualWidth / 2;
    double centerY = ActualHeight / 2;
    
    // 计算相对位置 (-1 到 1)
    double relX = (position.X - centerX) / centerX;
    double relY = (position.Y - centerY) / centerY;
    
    // 创建音效播放器
    var player = new MediaPlayer();
    player.Open(new Uri("sounds/click.wav", UriKind.Relative));
    
    // 应用平衡效果 (左右声道)
    player.Balance = Math.Clamp(relX, -1.0, 1.0);
    
    // 应用音量衰减
    double distance = Math.Sqrt(relX * relX + relY * relY);
    player.Volume = Math.Clamp(1.0 - distance * 0.5, 0.2, 1.0);
    
    player.Play();
}

3. 音效池系统

public class SoundPool
{
    private readonly List<MediaPlayer> _players = new List<MediaPlayer>();
    private readonly string _soundPath;
    private readonly double _volume;
    private int _currentIndex = 0;

    public SoundPool(string soundPath, int poolSize = 5, double volume = 1.0)
    {
        _soundPath = soundPath;
        _volume = volume;
        
        // 初始化播放器池
        for (int i = 0; i < poolSize; i++)
        {
            var player = new MediaPlayer();
            player.Open(new Uri(soundPath, UriKind.Relative));
            player.Volume = volume;
            _players.Add(player);
        }
    }

    public void Play()
    {
        // 选择下一个播放器
        var player = _players[_currentIndex];
        
        // 重置位置
        player.Position = TimeSpan.Zero;
        player.Play();
        
        // 移动到下一个播放器
        _currentIndex = (_currentIndex + 1) % _players.Count;
    }
}

// 使用
private SoundPool _clickSoundPool = new SoundPool("sounds/click.wav", 5, 0.7);

private void Button_Click(object sender, RoutedEventArgs e)
{
    _clickSoundPool.Play();
}

专业建议

1. 音效文件处理

• 使用16位PCM WAV格式以获得最佳兼容性
• 保持音效文件短小（通常小于500ms）
• 使用44.1kHz采样率
• 预加载常用音效以减少延迟

2. 性能优化

// 预加载音效
private void PreloadSounds()
{
    // 使用后台线程预加载
    Task.Run(() =>
    {
        var player = new MediaPlayer();
        player.Open(new Uri("sounds/click.wav", UriKind.Relative));
        
        // 预读到内存
        player.Play();
        player.Pause();
        player.Position = TimeSpan.Zero;
    });
}

// 使用NAudio进行低延迟播放
private void PlayLowLatencySound(string path)
{
    using (var audioFile = new AudioFileReader(path))
    using (var outputDevice = new WaveOutEvent())
    {
        outputDevice.Init(audioFile);
        outputDevice.Play();
    }
}

3. 无障碍支持

// 检查用户是否启用了声音
private bool IsSoundEnabled()
{
    // 检查系统设置
    bool systemSoundEnabled = SystemParameters.ClientAudioPlayback;
    
    // 检查用户偏好
    bool userPreference = Properties.Settings.Default.SoundEnabled;
    
    return systemSoundEnabled && userPreference;
}

// 提供视觉反馈替代
private void PlaySoundWithVisualFeedback()
{
    if (IsSoundEnabled())
    {
        PlayGlobalClickSound();
    }
    else
    {
        // 提供视觉反馈
        var button = sender as Button;
        var originalBrush = button.Background;
        
        button.Background = Brushes.Gray;
        
        // 短暂延迟后恢复
        Task.Delay(100).ContinueWith(_ => 
        {
            Dispatcher.Invoke(() => button.Background = originalBrush);
        });
    }
}

这个实现提供了多种按钮点击音效的实现方式，从简单的直接事件处理到高级的音效管理系统和3D音效效果。您可以根据项目需求选择合适的实现方法，
