O SoundPlayer classe fornece uma interface simples para carregar e reproduzir um arquivo. wav.The SoundPlayer class provides a simple interface for loading and playing a .wav file. O SoundPlayer classe dá suporte ao carregamento de um arquivo. wav de um caminho de arquivo, uma URL, um Stream que contém um arquivo. wav ou um recurso incorporado que contém um arquivo. wav.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.

Para reproduzir um som usando a SoundPlayer classe, configure um SoundPlayer com um caminho para o arquivo. wav e chame um dos métodos play.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. Você pode identificar o arquivo. wav para reproduzir usando um dos construtores ou configuração tanto a SoundLocation ou Stream propriedade.You can identify the .wav file to play by using one of the constructors or by setting either the SoundLocation or Stream property. O arquivo pode ser carregado antes da reprodução usando um dos métodos de carga ou carregamento pode ser adiado até que um dos métodos play é chamado.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. Um SoundPlayer configurado para carregar um arquivo. wav de um Stream ou a URL deve carregar o arquivo. wav na memória antes do início da reprodução.A SoundPlayer configured to load a .wav file from a Stream or URL must load the .wav file into memory before playback begins.

Você pode carregar ou reproduzir um arquivo. wav de forma síncrona ou assíncrona.You can load or play a .wav file synchronously or asynchronously. Se você chama um carregamento síncrono ou método play, o thread de chamada aguarda até que o método retorna, que pode causar a pintura e outros eventos para ser interrompido.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. Chamar um carregamento assíncrono ou o método play permitirá que o thread de chamada continuar sem interrupções.Calling an asynchronous load or play method will allow the calling thread to continue without interruption. Para obter mais informações sobre chamadas de método assíncrono, consulte como: Executar uma operação em segundo plano.For more information on asynchronous method calls, see How to: Run an Operation in the Background.

Quando um SoundPlayer terminou de carregar um arquivo. wav, ele gera o LoadCompleted eventos.When a SoundPlayer has finished loading a .wav file, it raises the LoadCompleted event. Você pode examinar o AsyncCompletedEventArgs no manipulador de eventos para determinar se a carga foi bem-sucedida ou falhou.You can examine the AsyncCompletedEventArgs in your event handler to determine if the load succeeded or failed. O SoundLocationChanged evento é gerado quando a fonte de áudio é definida como um novo caminho do arquivo ou URL.The SoundLocationChanged event is raised when the audio source is set to a new file path or URL. O StreamChanged evento é gerado quando a fonte de áudio é definida como um novo Stream.The StreamChanged event is raised when the audio source is set to a new Stream. Para obter mais informações sobre como manipular eventos, consulte tratando e gerando eventos.For more information about how to handle events, see Handling and Raising Events.

Observação

O SoundPlayer classe não pode executar outros tipos de arquivos como WMA ou. mp3.The SoundPlayer class cannot play other file types, such as .wma or .mp3. Se você quiser executar outros tipos de arquivo, você pode usar o controle do Windows Media Player.If you want to play other file types, you can use the Windows Media Player control. Para obter mais informações, consulte usando os controles do Windows Media Player em uma solução do .NET Framework e referência de modelo de objeto do Windows Media Player para Visual Basic .NET e C# no 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.
