IMethodMessage.ArgCount 속성

정의

‘메서드에 전달된 인수의 개수를 가져옵니다.Gets the number of arguments passed to the method.

public:
 property int ArgCount { int get(); };
[get: System.Security.SecurityCritical]
public int ArgCount { get; }
member this.ArgCount : int
Public ReadOnly Property ArgCount As Integer

속성 값

메서드에 전달된 인수의 개수입니다.The number of arguments passed to the method.

특성

예외

직접 실행 호출자가 인터페이스에 대한 참조를 통해 호출하며 인프라 권한이 없는 경우The immediate caller makes the call through a reference to the interface and does not have infrastructure permission.
