설명

클래스는 SoundPlayer .wav 파일을 로드하고 재생하기 위한 간단한 인터페이스를 제공합니다. 클래스는 SoundPlayer 파일 경로, URL Stream , .wav 파일이 포함된 또는 .wav 파일이 포함된 포함된 리소스에서 .wav 파일 로드를 지원합니다.

클래스를 사용하여 SoundPlayer 소리를 재생하려면 .wav 파일의 경로를 사용하여 을 구성 SoundPlayer 하고 재생 메서드 중 하나를 호출합니다. 생성자 중 하나를 사용하거나 또는 Stream 속성을 설정하여 재생할 .wav 파일을 식별할 SoundLocation 수 있습니다. 로드 메서드 중 하나를 사용하여 재생하기 전에 파일을 로드하거나 재생 방법 중 하나가 호출될 때까지 로드를 지연할 수 있습니다. SoundPlayer 또는 URL에서 .wav 파일을 로드하도록 구성된 는 Stream 재생이 시작되기 전에 .wav 파일을 메모리에 로드해야 합니다.

.wav 파일을 동기적으로 또는 비동기적으로 로드하거나 재생할 수 있습니다. 동기 로드 또는 재생 메서드를 호출하는 경우 호출 스레드는 메서드가 반환될 때까지 대기하므로 그리기 및 기타 이벤트가 중단될 수 있습니다. 비동기 로드 또는 재생 메서드를 호출하면 중단 없이 호출 스레드를 계속할 수 있습니다. 비동기 메서드 호출에 대한 자세한 내용은 방법: 백그라운드에서 작업 실행을 참조하세요.

SoundPlayer 가 .wav 파일 로드를 마치면 이벤트가 발생합니다LoadCompleted. 이벤트 처리기에서 를 AsyncCompletedEventArgs 검사하여 로드가 성공했는지 또는 실패했는지 확인할 수 있습니다. 오디오 SoundLocationChanged 소스가 새 파일 경로 또는 URL로 설정되면 이벤트가 발생합니다. 오디오 StreamChanged 소스가 새 Stream로 설정되면 이벤트가 발생합니다. 이벤트를 처리 하는 방법에 대 한 자세한 내용은 참조 하세요. 이벤트 처리 및 발생합니다.

에 대한 SoundPlayer자세한 내용은 SoundPlayer 클래스 개요를 참조하세요.

참고

클래스는 SoundPlayer .wma 또는 .mp3 같은 다른 파일 형식을 재생할 수 없습니다. 다른 파일 형식을 재생하려면 Windows 미디어 플레이어 컨트롤을 사용할 수 있습니다. 자세한 내용은 .NET Framework 솔루션에서 Windows 미디어 플레이어 컨트롤 사용 및 Windows 미디어 플레이어 SDK에서 Visual Basic .NET 및 C#에 대한 개체 모델 참조 Windows 미디어 플레이어 참조하세요.
