目前我开发了可以播放声音/音频功能的Windows 10移动应用程序。 当我写这个语句来播放音频/声音时,它会在Tap Tapped事件被点击时显示错误。 源代码如下:
MediaElement mysong = new MediaElement();
try
{
var folder = await StorageFolder.GetFolderFromPathAsync(@"ms-appx://Assets/Media/");
if (folder != null)
{
var file = await folder.GetFileAsync("police_alarm.mp3");
if (file != null)
{
var stream = await file.OpenReadAsync();
mysong.SetSource(stream, file.ContentType);
mysong.Volume = 100;
mysong.Play();
}
}
else
{
MessageDialog dialog = new MessageDialog("Siren can't play !!! Please keep yourself safe !!!", "Error");
await dialog.ShowAsync();
}
}
catch(Exception ex)
{
MessageDialog dialog = new MessageDialog(ex.ToString(), "Error");
await dialog.ShowAsync();
}
是针对此的任何解决方案吗?
谢谢。

问题是您使用了错误的文件夹路径。
var folder = await StorageFolder.GetFolderFromPathAsync(@"ms-appx://Assets/Media/");
请使用以下代码替换文件夹路径。
string root = Windows.ApplicationModel.Package.Current.InstalledLocation.Path;
string path = root + @"\Assets\Media";
var folder = await StorageFolder.GetFolderFromPathAsync(path);
