ref 매개 변수(Visual Basic의 경우 ByRef) 매개 변수로 전달될 때 현재 형식을 나타내는 Type 개체를 반환합니다.

public:
 override Type ^ MakeByRefType();

public override Type MakeByRefType ();

override this.MakeByRefType : unit -> Type

Public Overrides Function MakeByRefType () As Type

반환

Type

ref 매개 변수(Visual Basic의 경우 ByRef) 매개 변수로 전달될 때 현재 형식을 나타내는 Type 개체입니다.

예제

다음 코드 예제에서는 동적 모듈, 라는 Sample추상 형식 및 라는 TestMethod추상 메서드를 만듭니다. TestMethod는 형식의 ref 매개 변수(ByRefVisual Basic의 경우) , 형식SampleSample에 대한 포인터 및 형식Sample의 배열을 사용합니다. 형식 Sample의 2차원 배열을 반환합니다. 코드 예제에서는 동적 모듈을 디스크에 저장하므로 Ildasm.exe(IL 디스어셈블러)를 사용하여 검사할 수 있습니다.

설명

메서드는 MakeByRefType 매개 변수 목록에 대한 형식(ByRefVisual Basic의 경우)을 생성하는 ref 방법을 제공합니다.

참고

MSIL(Microsoft Intermediate Language) 구문을 사용하여 현재 TypeBuilder 가 을 MyType나타내는 경우 이 메서드에서 반환된 형식은 입니다 MyType&.
