방법: 웹 서비스 메서드에서 throw한 예외 처리
이 항목은 레거시 기술과 관련된 것입니다. 이제 XML Web services와 XML Web services 클라이언트는 다음을 사용하여 만들어야 합니다. Windows Communication Foundation.
웹 서비스 메서드를 호출하는 다음 클라이언트 코드 예제에서는 웹 서비스 메서드가 throw하는 SoapException을 catch합니다. 클라이언트는 catch된 SoapException의 속성으로 HTML 테이블을 채웁니다. 웹 서비스 클라이언트에서 받은 SOAP 오류를 처리하는 방법에 대한 자세한 내용은 XML Web Services에서 예외 처리 및 throw를 참조하십시오.
