설명

RequestNotification 열거형을 사용 하 여 사용 합니다 CurrentNotification 의 속성은 HttpContext 파이프라인에서 어떤 이벤트가 현재 처리 중인 확인 하려면 클래스.The RequestNotification enumeration is used with the CurrentNotification property of the HttpContext class to determine what event in the pipeline is currently processing. 시기를 결정 하의 특정 이벤트에 대 한 모든 처리기를 HttpApplication 인스턴스 처리를 완료 한, 사용 된 IsPostNotification 속성.To determine when all the handlers for a specific event of the HttpApplication instance have finished processing, use the IsPostNotification property.

합니다 RequestNotification 형식에 도입 된는 .NET Framework 3.5.NET Framework 3.5합니다.The RequestNotification type is introduced in the .NET Framework 3.5.NET Framework 3.5. 자세한 내용은 버전 및 종속성을 참조하세요.For more information, see Versions and Dependencies.
