예제

다음 예제에서는 속성을 사용 하 여 AppRelativeCurrentExecutionFilePath 페이지와 동일한 디렉터리에 있는 이미지에 컨트롤의 Image URL을 설정 합니다. 디렉터리 구조의 다른 수준에서 이 페이지를 실행하여 결과 AppRelativeCurrentExecutionFilePath 속성 값을 확인합니다.

설명

이 속성을 사용 하 여 애플리케이션 위치를 변경 하는 경우에 그대로 유지 됩니다 하는 URL 정보를 제공 합니다. 따라서 동일한 URL 매핑 코드를, 최종 배포 환경 및 테스트 환경에서 사용 되거나 다른 도메인에서 웹 애플리케이션의 복사본에서 사용할 수 있습니다.
