IMethodMessage.HasVarArgs 속성

정의

네임스페이스:

System.Runtime.Remoting.Messaging

어셈블리:

mscorlib.dll

메시지에 가변 인수가 있는지 나타내는 값을 가져옵니다.

public:
 property bool HasVarArgs { bool get(); };

public bool HasVarArgs { [System.Security.SecurityCritical] get; }

[<get: System.Security.SecurityCritical>]
member this.HasVarArgs : bool

Public ReadOnly Property HasVarArgs As Boolean

속성 값

Boolean

메서드가 가변 인수를 수락하면 true이고, 그렇지 않으면 false입니다.

특성

SecurityCriticalAttribute

예외

SecurityException

직접 실행 호출자가 인터페이스에 대한 참조를 통해 호출하며 인프라 권한이 없는 경우

예제

다음 예제 코드에서는 사용자 지정 프록시를 해당 재정의 RealProxy.Invoke 메서드 호출에 가변 인수가 있는지 여부를 포함 하 여 콘솔에 메시지 정보를 기록 하기 위해.
