지정된 HttpListenerResponse의 속성을 이 응답에 복사합니다.

public:
 void CopyFrom(System::Net::HttpListenerResponse ^ templateResponse);
public void CopyFrom (System.Net.HttpListenerResponse templateResponse);
member this.CopyFrom : System.Net.HttpListenerResponse -> unit
Public Sub CopyFrom (templateResponse As HttpListenerResponse)

매개 변수

templateResponse
HttpListenerResponse

복사할 HttpListenerResponse 인스턴스입니다.

예제

다음 코드 예제에서는 템플릿 응답을 복사하여 응답을 만드는 방법을 보여 줍니다.

설명

많은 속성을 기본값에서 고정된 새 값 집합으로 정기적으로 변경하는 경우 인스턴스를 HttpListenerResponse 템플릿으로 사용하는 것이 편리합니다. 템플릿 응답을 한 번 사용자 지정하고 각 응답을 별도로 구성하는 대신 메서드를 CopyFrom 호출하여 템플릿 응답의 속성 값을 기반으로 새 응답을 구성합니다.

다음 속성은 에서 templateResponse 현재 인스턴스로 복사됩니다.
