playing byte[] using naudio

  1. How can I convert an audio file to byte[] and play it using Naudio? (code will be appreciated)

  2. Also related to question above, how to play audio file in Resource using Naudio? For the second question I have this code:

    IWavePlayer waveOutDevice;
IWaveProvider provider;

public void PlaySound(byte[] sound)
{
  waveoutDevice = new WaveOutEvent();
  provider = new RawSourceWaveStrem(new MemoryStream(sound), new WaveFormat();
  if (waveOutDevice != null)
  waveOutDevice.Stop();
  waveOutDevice.Init(provider);
  waveOutDevice.Play();

}

    In my form constructor I then do something like - 

    PlaySound(Properties.Resources.beepsound)

    beepsound being the sound file....but I just hear a noise when this method is called. What could be wrong?

The WaveFileReader class can accept a Stream as a parameter, so you can use a MemoryStream to encapsulate a byte[] buffer whose contents you have loaded from a file.

Something like this:

byte[] fileContent = File.ReadAllBytes(@"C:\Some\File.wav");
var waveFileReader = new WaveFileReader(new MemoryStream(fileContent), true);

You can use GetManifestResourceStream or similar to get a stream for a resource and use that. If you want to reuse the streams, pass false as the second parameter which will stop them being disposed along with the WaveFileReader instance.
