Hinweise

Die SoundPlayer -Klasse stellt eine einfache Schnittstelle zum Laden und Wiedergeben einer WAV-Datei bereit.The SoundPlayer class provides a simple interface for loading and playing a .wav file. Die SoundPlayer -Klasse unterstützt das Laden einer WAV-Datei aus einem Dateipfad, Stream einer URL, einer, die eine WAV-Datei enthält, oder einer eingebetteten Ressource, die eine WAV-Datei enthält.The SoundPlayer class supports loading a .wav file from a file path, a URL, a Stream that contains a .wav file, or an embedded resource that contains a .wav file.

Um mit der SoundPlayer -Klasse einen Sound wiederzugeben, SoundPlayer konfigurieren Sie eine mit einem Pfad zur WAV-Datei, und nennen Sie eine der Play-Methoden.To play a sound using the SoundPlayer class, configure a SoundPlayer with a path to the .wav file and call one of the play methods. Sie können die zu Wiedergabe enden WAV-Datei mithilfe eines der-Konstruktoren oder durch Festlegen der-Eigenschaft SoundLocation oder Stream der-Eigenschaft identifizieren.You can identify the .wav file to play by using one of the constructors or by setting either the SoundLocation or Stream property. Die Datei kann vor der Wiedergabe mit einer der Load-Methoden geladen werden, oder der Ladevorgang kann verzögert werden, bis eine der Wiedergabe Methoden aufgerufen wird.The file can be loaded prior to playing by using one of the load methods, or loading can be deferred until one of the play methods is called. Ein SoundPlayer , das zum Laden einer WAV-Datei aus Stream einer-oder-URL konfiguriert ist, muss die WAV-Datei in den Speicher laden, bevor die Wiedergabe beginntA SoundPlayer configured to load a .wav file from a Stream or URL must load the .wav file into memory before playback begins.

Eine WAV-Datei kann synchron oder asynchron geladen oder wiedergegeben werden.You can load or play a .wav file synchronously or asynchronously. Wenn Sie eine synchrone Lade-oder Wiedergabemethode aufrufen, wartet der aufrufende Thread, bis die Methode zurückkehrt, was dazu führen kann, dass das Zeichnen und andere Ereignisse unterbrochen werden.If you call a synchronous load or play method, the calling thread will wait until the method returns, which may cause painting and other events to be interrupted. Wenn Sie eine asynchrone Lade-oder Wiedergabemethode aufrufen, kann der aufrufende Thread ohne Unterbrechung fortgesetzt werden.Calling an asynchronous load or play method will allow the calling thread to continue without interruption. Weitere Informationen zu asynchronen Methoden aufrufen finden Sie unter Gewusst wie: Ausführen eines Vorgangs im Hintergrund.For more information on asynchronous method calls, see How to: Run an Operation in the Background.

Wenn ein SoundPlayer das Laden einer WAV-Datei abgeschlossen hat, löst es LoadCompleted das-Ereignis aus.When a SoundPlayer has finished loading a .wav file, it raises the LoadCompleted event. Sie können die AsyncCompletedEventArgs in Ihrem Ereignishandler überprüfen, um zu ermitteln, ob die Last erfolgreich oder fehlerhaft war.You can examine the AsyncCompletedEventArgs in your event handler to determine if the load succeeded or failed. Das SoundLocationChanged -Ereignis wird ausgelöst, wenn die Audioquelle auf einen neuen Dateipfad oder eine neue URL festgelegt ist.The SoundLocationChanged event is raised when the audio source is set to a new file path or URL. Das StreamChanged -Ereignis wird ausgelöst, wenn die Audioquelle auf einen neuen Streamfestgelegt ist.The StreamChanged event is raised when the audio source is set to a new Stream. Weitere Informationen zum Behandeln von Ereignissen finden Sie unter behandeln und Auslösen von Ereignissen.For more information about how to handle events, see Handling and Raising Events.

Weitere Informationen zu finden SoundPlayerSie unter Übersicht über die SoundPlayer-Klasse.For more information about SoundPlayer, see SoundPlayer Class Overview.

Hinweis

Die SoundPlayer Klasse kann keine anderen Dateitypen, wie z. b. WMA oder. MP3, wiedergeben.The SoundPlayer class cannot play other file types, such as .wma or .mp3. Wenn Sie andere Dateitypen wiedergeben möchten, können Sie das Windows Media Player-Steuerelement verwenden.If you want to play other file types, you can use the Windows Media Player control. Weitere Informationen finden Sie unter Verwenden des Windows Media Player-Steuer Elements in einer .NET Framework-Lösung und Windows Media Player-Objektmodell Referenz C# für Visual Basic .net und im Windows Media Player SDK.For more information, see Using the Windows Media Player Control in a .NET Framework Solution and Windows Media Player Object Model Reference for Visual Basic .NET and C# in the Windows Media Player SDK.
