SoundPlayerクラスの読み込みと .wav ファイルの再生、シンプルなインターフェイスを提供します。The SoundPlayer class provides a simple interface for loading and playing a .wav file. SoundPlayerクラスは、URL、ファイル パスから .wav ファイルの読み込みをサポートするStream.wav ファイル、または .wav ファイルが含まれる埋め込みリソースを格納しています。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.

使用してサウンドを再生する、SoundPlayerクラス、構成、 SoundPlayer .wav ファイルと再生のいずれかの呼び出しにパスを使用します。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. コンス トラクターのいずれかを使用して、またはいずれかを設定して再生する .wav ファイルを識別する、SoundLocationまたはStreamプロパティ。You can identify the .wav file to play by using one of the constructors or by setting either the SoundLocation or Stream property. Load メソッドのいずれかを使用して再生する前に、ファイルを読み込むことがまたは読み込みは、play メソッドのいずれかが呼び出されるまで延期できます。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. ASoundPlayerから .wav ファイルを読み込むように構成、 Stream URL は、再生を開始する前に、メモリの .wav ファイルを読み込む必要がありますか。A SoundPlayer configured to load a .wav file from a Stream or URL must load the .wav file into memory before playback begins.

読み込みまたは .wav ファイルの同期または非同期で再生できます。You can load or play a .wav file synchronously or asynchronously. 同期のロードを呼び出すメソッドを再生するか、呼び出し元のスレッドはの中断は、描画、およびその他のイベントを引き起こす可能性のあるメソッドからまで待機します。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. 非同期の読み込みまたは play メソッドを呼び出すと、呼び出し元のスレッドを中断せずに続行することができます。Calling an asynchronous load or play method will allow the calling thread to continue without interruption. 非同期メソッド呼び出しの詳細については、次を参照してください。方法: バック グラウンドで操作を実行します。For more information on asynchronous method calls, see How to: Run an Operation in the Background.

ときに、 SoundPlayer .wav ファイルの読み込みが完了しましたが発生、LoadCompletedイベント。When a SoundPlayer has finished loading a .wav file, it raises the LoadCompleted event. 調べることができます、AsyncCompletedEventArgs負荷が成功または失敗したかどうかを判断するイベント ハンドラーでします。You can examine the AsyncCompletedEventArgs in your event handler to determine if the load succeeded or failed. SoundLocationChangedオーディオ ソースが新しいファイル パスまたは URL に設定されている場合、イベントが発生します。The SoundLocationChanged event is raised when the audio source is set to a new file path or URL. StreamChangedを新しいオーディオ ソースが設定されている場合、イベントが発生したStreamします。The StreamChanged event is raised when the audio source is set to a new Stream. イベントを処理する方法の詳細については、次を参照してください。処理とイベントの発生します。For more information about how to handle events, see Handling and Raising Events.

詳細についてはSoundPlayerを参照してくださいSoundPlayer クラスの概要します。For more information about SoundPlayer, see SoundPlayer Class Overview.

注意

SoundPlayerクラスは、.wma、.mp3 などの他のファイルの種類を再生できません。The SoundPlayer class cannot play other file types, such as .wma or .mp3. その他のファイルの種類を再生する場合は、Windows Media Player コントロールを使用できます。If you want to play other file types, you can use the Windows Media Player control. 詳細については、次を参照してください.NET Framework ソリューションで、Windows Media Player コントロールを使用してVisual Basic .NET と c# の Windows Media Player オブジェクト モデル リファレンス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.
