I'm making a small media player where I add mediafiles to a listbox which works as a playlist for the mediaelement. When I click on an item in the listbox it starts to play. What I would like to do is to make the mediaelement automatically start playing the next song/video in the listbox after the current has ended.
Here's how I add songs to the listbox:
OpenFileDialog ofd = new OpenFileDialog();
ofd.Multiselect = true;
if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
foreach (string file in ofd.FileNames)
{
FileInfo fileName = new FileInfo(file);
listBox.Items.Add(fileName);
}
}
and here's how I can click on an item in the listbox and it starts to play
private void Button_Click(object sender, RoutedEventArgs e)
{
System.Windows.Controls.Button prevButton = player.Tag as System.Windows.Controls.Button;
System.Windows.Controls.Button button = sender as System.Windows.Controls.Button;
FileInfo fileInfo = button.DataContext as FileInfo;
// If a file is playing, stop it
if (prevButton != null)
{
player.Tag = null;
player.Stop();
prevButton.Background = Brushes.White;
// if the one thats playing is the one that was clicked -> don't play it
if (prevButton == button)
return;
}
// Play the one that was clicked
player.Tag = button;
player.Source = new Uri(fileInfo.FullName);
player.Play();
}
Subscribe to the MediaEnded event of the MediaElement or MediaPlayer and then pick the next item from the listbox.
EDIT
How to pick the next item:
The code below hasn't been checked by a compiler!
private int currentSongIndex = -1;
void Player_MediaEnded(object sender, EventArgs e)
{
if(currentSongIndex == -1)
{
currentSongIndex = listBox.SelectedIndex;
}
currentSongIndex++;
if(currentSongIndex < listBox.Items.Count)
{
player.Play(listBox.Items[currentSongIndex]);
}
else
{
// last song in listbox has been played
}
}
