不支持 URI 前缀

我正在尝试使用以下方法加载和播放波形文件：

SoundPlayer simpleSound = new SoundPlayer(@"pack://application:,,,/MyAssembly;component/Sounds/10meters.wav");
            simpleSound.Play();

但没有成功。我得到一个 System.NotSupportedException :( 见下文。

System.NotSupportedException: The URI prefix is not recognized.
   at System.Net.WebRequest.Create(Uri requestUri, Boolean useUriBase)
   at System.Net.WebRequest.Create(Uri requestUri)
   at System.Media.SoundPlayer.LoadSync()
   at System.Media.SoundPlayer.LoadAndPlay(Int32 flags)
   at System.Media.SoundPlayer.Play()

我查看了谷歌并试图找到解决方案，但没有任何效果。使用直接路径播放文件效果很好

SoundPlayer simpleSound = new SoundPlayer(@"D:\Projects\MyAssembly\Sounds\10meters.wav");
simpleSound.Play();

我还检查了 MyAssembly 内容，资源就在那里。 SoundPlayer 是否不支持打包或者我有什么做得不正确的地方？

I am trying to load and play a wave file using:

SoundPlayer simpleSound = new SoundPlayer(@"pack://application:,,,/MyAssembly;component/Sounds/10meters.wav");
            simpleSound.Play();

With no success. I get a System.NotSupportedException :( see below.

System.NotSupportedException: The URI prefix is not recognized.
   at System.Net.WebRequest.Create(Uri requestUri, Boolean useUriBase)
   at System.Net.WebRequest.Create(Uri requestUri)
   at System.Media.SoundPlayer.LoadSync()
   at System.Media.SoundPlayer.LoadAndPlay(Int32 flags)
   at System.Media.SoundPlayer.Play()

I looked over google and SO trying to find a solution, nothing worked.
Playing the file with a direct path works fine

SoundPlayer simpleSound = new SoundPlayer(@"D:\Projects\MyAssembly\Sounds\10meters.wav");
simpleSound.Play();

I also checked MyAssembly content, the resource is there.
Does SoundPlayer not support packing or there anything I am not doing correctly?

pack:// URI 方案特定于 WPF，因此非 WPF 组件不知道如何处理它...但是，您可以检索此资源的流，并将其传递给SoundPlayer 构造函数：

Uri uri = new Uri(@"pack://application:,,,/MyAssembly;component/Sounds/10meters.wav");
StreamResourceInfo sri = Application.GetResourceStream(uri);
SoundPlayer simpleSound = new SoundPlayer(sri.Stream);
simpleSound.Play();

另一个选项是使用 MediaPlayer 类：

Uri uri = new Uri(@"pack://application:,,,/MyAssembly;component/Sounds/10meters.wav");
MediaPlayer player = new MediaPlayer();
player.Open(uri);
player.Play();

该类支持 pack:// URI 方案

The pack:// URI scheme is specific to WPF, so non-WPF components don't know how to handle it... however, you can retrieve a stream for this resource, and pass it to the SoundPlayer constructor:

Uri uri = new Uri(@"pack://application:,,,/MyAssembly;component/Sounds/10meters.wav");
StreamResourceInfo sri = Application.GetResourceStream(uri);
SoundPlayer simpleSound = new SoundPlayer(sri.Stream);
simpleSound.Play();

Another option is to use the MediaPlayer class:

Uri uri = new Uri(@"pack://application:,,,/MyAssembly;component/Sounds/10meters.wav");
MediaPlayer player = new MediaPlayer();
player.Open(uri);
player.Play();

This class supports the pack:// URI scheme
