Source:

FtpWebResponse.cs

FTP 서버에서 보낸 응답 데이터를 포함하는 스트림을 검색합니다.

public:
 override System::IO::Stream ^ GetResponseStream();

public override System.IO.Stream GetResponseStream ();

override this.GetResponseStream : unit -> System.IO.Stream

Public Overrides Function GetResponseStream () As Stream

반환

Stream

응답과 함께 반환된 데이터를 포함하는 읽기 가능한 Stream 인스턴스이거나, 서버에서 응답 데이터를 반환하지 않은 경우 Null입니다.

예외

InvalidOperationException

응답에 데이터 스트림이 반환되지 않은 경우
