Public Overridable Function MakeByRefType () As Type

반환

Type(Visual Basic의 경우 ref) 매개 변수로 전달될 때 현재 형식을 나타내는 ByRef 개체입니다.A Type object that represents the current type when passed as a ref parameter (ByRef parameter in Visual Basic).

예외

호출된 메서드가 기본 클래스에서 지원되지 않습니다.The invoked method is not supported in the base class.

현재 형식이 TypedReference입니다.The current type is TypedReference.

또는-or- 현재 형식이 ByRef 형식입니다.The current type is a ByRef type. 즉, IsByReftrue를 반환합니다.That is, IsByRef returns true.

예제

다음 코드 예제에서는 배열에 ref (ByRef Visual basic에서), 및 포인터 형식에는 Test 클래스.The following code example creates array, ref (ByRef in Visual Basic), and pointer types for the Test class.

      // Get a Type object representing the Example class, a
      // MethodInfo representing the "Test" method, a ParameterInfo
      // representing the parameter of type Example, and finally
      // a Type object representing the type of this ByRef parameter.
      // Compare this Type object with the Type object created using
      // MakeByRefType.
      Type^ t2 = Example::typeid;
      MethodInfo^ mi = t2->GetMethod( L"Test" );
      ParameterInfo^ pi = mi->GetParameters()[ 0 ];
      Type^ pt = pi->ParameterType;
      Console::WriteLine( L"Are the ByRef types equal? {0}", (t == pt) );
      
      // Create a Type object that represents a pointer to an
      // Example object.
      t = Example::typeid->MakePointerType();
      Console::WriteLine( L"\r\nPointer to Example: {0}", t );
   }

   // A sample method with a ByRef parameter.
   //
   void Test( interior_ptr<Example^> /*e*/ )
   {

설명

합니다 MakeByRefType 메서드를 생성 하는 방법을 제공 ref 형식 (ByRef Visual basic에서) 매개 변수를 나열 합니다.The MakeByRefType method provides a way to generate ref types (ByRef in Visual Basic) for parameter lists.

경우 MSIL (Microsoft intermediate language), 구문을 사용 하 여 현재 Type 개체가 나타내는 Int32,이 메서드는 반환을 Type 개체를 나타내는 Int32&합니다.Using the syntax of Microsoft intermediate language (MSIL), if the current Type object represents Int32, this method returns a Type object representing Int32&.
