AppDomain.DoCallBack 메서드

  • 아티클

지정한 대리자에서 식별한 다른 응용 프로그램 도메인에 있는 코드를 실행합니다.

네임스페이스: System
어셈블리: mscorlib(mscorlib.dll)

구문

‘선언
Public Sub DoCallBack ( _
    callBackDelegate As CrossAppDomainDelegate _
)
‘사용 방법
Dim instance As AppDomain
Dim callBackDelegate As CrossAppDomainDelegate

instance.DoCallBack(callBackDelegate)

public void DoCallBack (
    CrossAppDomainDelegate callBackDelegate
)

public:
virtual void DoCallBack (
    CrossAppDomainDelegate^ callBackDelegate
) sealed

public final void DoCallBack (
    CrossAppDomainDelegate callBackDelegate
)

public final function DoCallBack (
    callBackDelegate : CrossAppDomainDelegate
)

매개 변수

  • callBackDelegate
    호출할 메서드를 지정하는 대리자입니다.

설명

callBackDelegate에서는 값으로 마샬링한 MarshalByRefObject 또는 ContextBoundObject를 지정할 수 있습니다.
