CallContext.GetHeaders 메서드

정의

네임스페이스:

System.Runtime.Remoting.Messaging

어셈블리:

mscorlib.dll

메서드 호출과 함께 보낸 헤더를 반환합니다.

public:
 static cli::array <System::Runtime::Remoting::Messaging::Header ^> ^ GetHeaders();

[System.Security.SecurityCritical]
public static System.Runtime.Remoting.Messaging.Header[] GetHeaders ();

[<System.Security.SecurityCritical>]
static member GetHeaders : unit -> System.Runtime.Remoting.Messaging.Header[]

Public Shared Function GetHeaders () As Header()

반환

Header[]

메서드 호출과 함께 보낸 헤더입니다.

특성

SecurityCriticalAttribute

예외

SecurityException

직접 실행 호출자에 인프라 권한이 없는 경우

예제

다음 코드 예제에서는 원격 메서드에 헤더를 보내고 원격 메서드가 반환할 때 해당 헤더의 콘텐츠를 콘솔에 출력합니다.
