Playing a MP3 file in a WinForm application

1. first go to the properties of your project
2. click on add references

3. add the library under COM object for window media player then type your code where you want

   
   Source:

       WMPLib.WindowsMediaPlayer wplayer = new WMPLib.WindowsMediaPlayer();
   
       wplayer.URL = @"C:\Users\Adil M\Documents\Visual Studio 2012\adil.mp3";
       wplayer.controls.play();
   

The link below, gives a very good tutorial, about playing mp3 files from a windows form with c#:

This link will lead you to a topic, which contains a lot information about how to play an mp3 song, using Windows forms. It also contains a lot of other projects, trying to achieve the same thing:

For example use this code for .mp3:

WMPLib.WindowsMediaPlayer wplayer = new WMPLib.WindowsMediaPlayer();

wplayer.URL = "My MP3 file.mp3";
wplayer.Controls.Play();

Then only put the wplayer.Controls.Play(); in the Button_Click event.

For example use this code for .wav:

System.Media.SoundPlayer player = new System.Media.SoundPlayer();

player.SoundLocation = "Sound.wav";
player.Play();

Put the player.Play(); in the Button_Click event, and it will work.

1) The most simple way would be using WMPLib

WMPLib.WindowsMediaPlayer Player;

private void PlayFile(String url)
{
    Player = new WMPLib.WindowsMediaPlayer();
    Player.PlayStateChange += Player_PlayStateChange;
    Player.URL = url;
    Player.controls.play();
}

private void Player_PlayStateChange(int NewState)
{
    if ((WMPLib.WMPPlayState)NewState == WMPLib.WMPPlayState.wmppsStopped)
    {
        //Actions on stop
    }
}

2) Alternatively you can use the open source library NAudio. It can play mp3 files using different methods and actually offers much more than just playing a file.

This is as simple as

using NAudio;
using NAudio.Wave;

IWavePlayer waveOutDevice = new WaveOut();
AudioFileReader audioFileReader = new AudioFileReader("Hadouken! - Ugly.mp3");

waveOutDevice.Init(audioFileReader);
waveOutDevice.Play();

Don't forget to dispose after the stop

waveOutDevice.Stop();
audioFileReader.Dispose();
waveOutDevice.Dispose();
