설명

하위 클래스 Method 에서 재정의되는 경우 이 요청에 사용할 요청 메서드가 속성에 포함됩니다.

참고

WebRequest 클래스는 클래스입니다abstract. 런타임에 인스턴스의 WebRequest 실제 동작은 메서드에서 반환된 하위 클래스에 의해 WebRequest.Create 결정됩니다. 기본값 및 예외에 대한 자세한 내용은 하위 클래스(예 HttpWebRequest : 및 FileWebRequest)에 대한 설명서를 참조하세요.

구현자 참고

이 속성에는 Method 구현된 프로토콜에 대한 유효한 요청 메서드가 포함될 수 있습니다. 기본값은 프로토콜별 속성을 설정할 필요가 없는 기본 요청/응답 트랜잭션을 제공해야 합니다.
