问题描述

在 windows phone 7 中添加媒体元素?
即使正确提供属性,media 元素也无法播放音频.
media element doesn't play audio even correctly giving the properties.
推荐答案
确实有效.
在代码中:
using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
var stream = TitleContainer.OpenStream("beep.wav");
var effect = SoundEffect.FromStream(stream);
effect.Play();
注意beep.wav"必须配置为内容".
N.B. "beep.wav" must be configured as "Content".
在应用构造函数中添加:
In app constructor add:
this.ApplicationLifetimeObjects.Add(new XNAAsyncDispatcher(TimeSpan.FromMilliseconds(50)));
还要添加以下类:
public class XNAAsyncDispatcher : IApplicationService
{
private DispatcherTimer frameworkDispatcherTimer;
public XNAAsyncDispatcher(TimeSpan dispatchInterval)
{
this.frameworkDispatcherTimer = new DispatcherTimer();
this.frameworkDispatcherTimer.Tick += new EventHandler(frameworkDispatcherTimer_Tick);
this.frameworkDispatcherTimer.Interval = dispatchInterval;
}
void IApplicationService.StartService(ApplicationServiceContext context) { this.frameworkDispatcherTimer.Start(); }
void IApplicationService.StopService() { this.frameworkDispatcherTimer.Stop(); }
void frameworkDispatcherTimer_Tick(object sender, EventArgs e) { FrameworkDispatcher.Update(); }
}
