解説

SoundPlayer クラスには、.wav ファイルの読み込みと再生のための簡単なインターフェイスが用意されています。SoundPlayer クラスは、ファイルパス、URL、または .wav ファイルを格納している Stream や埋め込みリソースからの .wav ファイルの読み込みをサポートしています。

SoundPlayer クラスを使用してサウンドを再生するには、SoundPlayer に .wav ファイルのパスを設定し、play メソッドの 1 つを呼び出します。いずれかのコンストラクタを使用するか、SoundLocation プロパティまたは Stream プロパティのどちらかを設定して、再生する .wav ファイルを指定できます。再生する前に、load メソッドの 1 つを使用してファイルを読み込むことも、いずれかの play メソッドが呼び出されるまで読み込みを延期することもできます。Stream または URL から .wav ファイルを読み込むように構成された SoundPlayer は、再生を開始する前に .wav ファイルをメモリに読み込む必要があります。

同期的または非同期的に、.wav ファイルを読み込んだり再生したりできます。同期的に実行される load メソッドまたは play メソッドを呼び出す場合、呼び出し元のスレッドはそのメソッドから制御が戻るまで待機します。この場合、描画などの他のイベントは中断される場合があります。非同期的に実行される load メソッドまたは play メソッドを呼び出す場合、呼び出し元のスレッドは中断されることなく続行できます。非同期メソッド呼び出しの詳細については、「方法 : バックグラウンドで操作を実行する」を参照してください。

SoundPlayer が .wav ファイルの読み込みを完了すると、LoadCompleted イベントが発生します。イベントハンドラで AsyncCompletedEventArgs をチェックして、読み込みが成功したか失敗したかを判断できます。オーディオソースに新しいファイルパスまたは新しい URL が設定されると、SoundLocationChanged イベントが発生します。オーディオソースに新しい Stream が設定されると、StreamChanged イベントが発生します。イベント処理の詳細については、「イベントの利用」を参照してください。

SoundPlayer の詳細については、「SoundPlayer クラスの概要」を参照してください。
