我有很多的.wav文件的播放，並因爲我創建AudioItem類：Windows Phone的聲音播放
public class AudioItem
{
public string SongName { get; set; }
public string SongText { get; set; }
public AudioItem()
{ }
/// <summary>
/// Initialize AudioItem class
/// </summary>
/// <param name="SongName">The name of the song(with .wav)</param>
/// <param name="SongText">Text to display</param>
public AudioItem(string SongName, string SongText)
{
this.SongName = SongName;
this.SongText = SongText;
}
public void Play()
{
var stream = TitleContainer.OpenStream("Sound/" + SongName);
var effect = SoundEffect.FromStream(stream);
FrameworkDispatcher.Update();
effect.Play();
}
}
在視圖中我有一個項目Listbox：
<ListBox Name="soundtrackLbx">
<ListBox.ItemTemplate>
<DataTemplate>
<Button Name="ListButton" HorizontalAlignment="Stretch" >
<Button.Content>
<StackPanel Orientation="Horizontal">
<Image Margin="10" Height="30" Width="30" Source="Picture/audio.png"/>
<TextBlock Margin="10" HorizontalAlignment="Stretch" Text="{Binding SongText}" FontFamily="Verdana" Tap="TextBlock_Tap" />
</StackPanel>
</Button.Content>
</Button>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
我代碼背後：
public ObservableCollection<AudioItem> AudioItems { get; set; }
public MainView()
{
InitializeComponent();
AudioItems = new ObservableCollection<AudioItem>();
Initialize();
this.soundtrackLbx.ItemsSource = AudioItems;
}
private void Initialize()
{
AudioItems.Add(new AudioItem("ApsolutnoDa.wav", "Apsolutno da"));
AudioItems.Add(new AudioItem("Da.wav", "Da"));
}
private void TextBlock_Tap(object sender, GestureEventArgs e)
{
TextBlock tblock = sender as TextBlock;
string text = tblock.Text;
AudioItem item = AudioItems.SingleOrDefault(a => a.SongText == text);
item.Play();
}
好吧，碰巧.wav有時我聽到他們在玩，有時候我不會，我不知道爲什麼。
