How can i play mp3 from Resource using nAudio in WPF?

Question

I'm using nAudio to play a background song in my WPF Application. Now to start a new instace of a song the code to is this:

        private WaveStream CreateInputStream(string fileName)
    {
        WaveChannel32 inputStream;
        if (fileName.EndsWith(".mp3"))
        {
            WaveStream mp3Reader = new Mp3FileReader(fileName);
            inputStream = new WaveChannel32(mp3Reader);
        }
        else
        {
            throw new InvalidOperationException("Unsupported extension");
        }
        volumeStream = inputStream;
        return volumeStream;
    }

Which works fine, but only to a specific file path. Now if i try sending a Pack URL to this function, i get error that the format isn't supported. Anyone ever encouterd this and knows what i should do?

SOLVED : thanks to minitech answer, this code eventully worked :

 StreamResourceInfo resource = Application.GetResourceStream(
          new Uri("YearBook;component/Resources/Music/1.mp3", UriKind.Relative));
        mainOutputStream = CreateInputStream(resource.Stream);
        waveOutDevice.Init(mainOutputStream);


    private WaveStream CreateInputStream(Stream fileName)
    {
        WaveChannel32 inputStream;
        WaveStream mp3Reader = new Mp3FileReader(fileName);
        inputStream = new WaveChannel32(mp3Reader);
        volumeStream = inputStream;
        return volumeStream;
    }

The Mp3FileReader constructor is overloaded to take a stream. I don't know how WPF resources work, but if you can get your file as a Stream object somehow, then you can use that. Here's how you can play a byte[]:

private WaveStream CreateInputStream(byte[] resource) {
    WaveChannel32 inputStream;

    using(MemoryStream ms = new MemoryStream(resource)) {
        WaveStream mp3Reader = new Mp3FileReader(ms);
        inputStream = new WaveChannel32(mp3Reader);
    }

    return inputStream;
}
