我正在创建一个应用程序.. 我面临一个小问题。我想得到这个东西...我有一个单选按钮。现在,只要单击此单选按钮,我就想循环播放一小段音乐。我正在使用 Visual Studio .. 无法使用表达式。我正在使用以下代码..
public partial class Page3 : PhoneApplicationPage
{
private SoundEffect s1;
public Page3()
{
InitializeComponent();
GameTimer gameTimer = new GameTimer();
gameTimer.UpdateInterval = TimeSpan.FromMilliseconds(10000);
// Call FrameworkDispatcher.Update to update the XNA Framework internals.
gameTimer.Update += delegate { try { FrameworkDispatcher.Update(); } catch { } };
// Start the GameTimer running.
gameTimer.Start();
// Prime the pump or we'll get an exception.
FrameworkDispatcher.Update();
LoadSound("Views/1.wav", out s1);
}
private void LoadSound(String SoundFilePath, out SoundEffect Sound)
{
// For error checking, assume we'll fail to load the file.
Sound = null;
try
{
// Holds informations about a file stream.
StreamResourceInfo SoundFileInfo = App.GetResourceStream(new Uri(SoundFilePath, UriKind.Relative));
// Create the SoundEffect from the Stream
Sound = SoundEffect.FromStream(SoundFileInfo.Stream);
}
catch (NullReferenceException)
{
// Display an error message
MessageBox.Show("Couldn't load sound " + SoundFilePath);
}
}
private void radioButton1_Checked(object sender, RoutedEventArgs e)
{
try
{
s1.Play();
}
catch (NullReferenceException)
{
MessageBox.Show("Can't play, s1 is null.");
}
}
