Button pause music player

Question

I’m a programming intern and I’ve decided to do something I’ve never tried before, a music player. I am building the functions that each button should do but I noticed that I made a mistake in the Pause part by actually making the button stop the music, I wanted a lot of help to discover my mistake.

//===================================================================================
//Começa a reproduzir a música escolhida
private void Iniciar_Click(object sender, RoutedEventArgs e)
{
    //Código que reproduz uma música escolhida
    System.Media.SoundPlayer player = new System.Media.SoundPlayer();
    player.SoundLocation = @"C:\Users\Juan\Desktop\Biblioteca do Juan\Praticando WPF\musicPlayer\musicPlayer\Vessel.WAV";
    player.Play();

    //esconder botão iniciar
    Iniciar.Visibility = Visibility.Collapsed;
    Pausar.Visibility = Visibility.Visible;

}

//===================================================================================
//Para a música que está sendo reproduzida
private void Pausar_Click(object sender, RoutedEventArgs e)
{
    //Código que para a música que está rodando
    System.Media.SoundPlayer player = new System.Media.SoundPlayer();
    player.Stop();

    //esconder butão pause
    Iniciar.Visibility = Visibility.Visible;
    Pausar.Visibility = Visibility.Collapsed;
}

Don’t use the class System.Media.SoundPlayer this is a very limited functionality and does not have the method Pause that you need.

Use the class System.Windows.Controls.MediaElement who possesses the methods Play, Pause and Stop.

To select the file to play you change the property Source.

Edited:

The class MediaElement only plays media if it has representation of the XAML tree.

Then in Toolbox select a media element:

In the XAML on the line MediaElement add the property Name="MediaElement1":

private void Iniciar_Click(object sender, RoutedEventArgs e)
{
        var openFileDialog1 = new OpenFileDialog();

        if (openFileDialog1.ShowDialog() == true)
        {
            //Essa linha pode ser colocada na inicialização. 
            //Está quai para mostrar sua necessidade.
            MediaElement1.LoadedBehavior = MediaState.Manual;

            MediaElement1.Stop();


            // Nescessário converter de string para uri
            MediaElement1.Source = new Uri(openFileDialog1.FileName);

            MediaElement1.Play();

            //mostra botão iniciar
            Iniciar.Visibility = Visibility.Visible;
            Pausar.Visibility = Visibility.Collapsed;
        }

}


private void Pausar_Click(object sender, RoutedEventArgs e)
{

    MediaElement1.Stop();

    //esconder butão pause
    Iniciar.Visibility = Visibility.Visible;
    Pausar.Visibility = Visibility.Collapsed;
}
