There is such a code (wrapper) for MediaElement'a, and that's when I noticed a lot of new initializations of the class EventHandler'a thought, is this correct? Actually the code below. Is there another way to do the same without creating a new EventHandler each time?
namespace Mynamespace.Controls { public class AnimePlayer : Border { public delegate void StateChangedEventHandler(object sender, AnimePlayerEventArgs animePlayerEventArgs); private readonly IMessageService _messageService; public AnimePlayer(IMessageService messageService) : this( messageService, new MediaElement {LoadedBehavior = MediaState.Manual, UnloadedBehavior = MediaState.Manual}) { } public AnimePlayer(IMessageService messageService, MediaElement mediaElement) { _messageService = messageService; MediaElement = mediaElement; CreateControl(); } private MediaElement MediaElement { get; } public event StateChangedEventHandler PlayerStateChanged; private void CreateControl() { Background = Brushes.Black; Child = new Grid { RowDefinitions = {new RowDefinition(), new RowDefinition {Height = GridLength.Auto}}, ColumnDefinitions = {new ColumnDefinition(), new ColumnDefinition()}, Children = {MediaElement} }; MediaElement.HorizontalAlignment = HorizontalAlignment.Center; MediaElement.VerticalAlignment = VerticalAlignment.Center; Grid.SetColumnSpan(MediaElement, 2); Grid.SetRowSpan(MediaElement, 2); MediaElement.MediaFailed += async (sender, args) => await _messageService.ShowErrorAsync(args.ErrorException); MediaElement.MediaOpened += (sender, args) => OnPlayerStateChanged(new AnimePlayerEventArgs(PlayerState.Playing)); MediaElement.BufferingStarted += (sender, args) => { OnPlayerStateChanged(new AnimePlayerEventArgs(PlayerState.Buffering, MediaElement.BufferingProgress)); }; MediaElement.MediaEnded += (sender, args) => { OnPlayerStateChanged(new AnimePlayerEventArgs(PlayerState.Stopped)); MediaElement.Stop(); MediaElement.Position = TimeSpan.Zero; }; } public void Play() { if (!MediaElement.HasAudio && !MediaElement.HasVideo && MediaElement.Source == null) return; OnPlayerStateChanged(new AnimePlayerEventArgs(PlayerState.Playing)); MediaElement.Play(); } public void Play(Uri mediaUri) { OpenMedia(mediaUri); Play(); } public void Pause() { if (!MediaElement.HasAudio && !MediaElement.HasVideo && MediaElement.Source == null) return; OnPlayerStateChanged(new AnimePlayerEventArgs(PlayerState.Paused)); MediaElement.Pause(); } public void OpenMedia(Uri mediaUri) { MediaElement.Source = mediaUri; } public void OpenMedia(Uri mediaUri, bool playOnOpen) { if (playOnOpen) { Play(mediaUri); return; } OpenMedia(mediaUri); } public void Close() { MediaElement.Close(); } /// <summary> /// Происходит при изменении StateNow /// </summary> /// <param name="animeplayereventargs"></param> protected virtual void OnPlayerStateChanged(AnimePlayerEventArgs animeplayereventargs) { PlayerStateChanged?.Invoke(this, animeplayereventargs); } public class AnimePlayerEventArgs : EventArgs { public AnimePlayerEventArgs() { } public AnimePlayerEventArgs(PlayerState playerState) { StateNow = playerState; } public AnimePlayerEventArgs(PlayerState playerState, double progressBuffering) : this(playerState) { BufferingProgress = progressBuffering; } /// <summary> /// Что делает проигрыватель /// </summary> public PlayerState StateNow { get; internal set; } public double BufferingProgress { get; internal set; } } } /// <summary> /// Состояние аниме проигрывателя /// </summary> public enum PlayerState { /// <summary> /// Проигрывает /// </summary> Playing, /// <summary> /// Приостоновлен /// </summary> Paused, /// <summary> /// Бефферизация /// </summary> Buffering, /// <summary> /// Медиа закрыто, простаивает /// </summary> Closed, /// <summary> /// Остановлен /// </summary> Stopped, /// <summary> /// Открытие мультимедиа /// </summary> MediaOpen } }
