방법: ASP.NET을 사용하여 만든 웹 서비스에서 예외 throw

이 항목은 레거시 기술과 관련된 것입니다. 이제 XML Web services와 XML Web services 클라이언트는 다음을 사용하여 만들어야 합니다. Windows Communication Foundation.

코드 예제

다음 코드 예제에서는 SoapException을 throw하고 Detail 속성을 설정하여 예외에 대한 자세한 정보를 표시합니다. ASP.NET 웹 서비스에서 예외를 throw하는 방법에 대한 자세한 내용은 XML Web Services에서 예외 처리 및 throw를 참조하십시오.
