RectangleF 값을 가장 가까운 정수 값으로 반올림하여 지정된 Rectangle를 RectangleF로 변환합니다.

public:
 static System::Drawing::Rectangle Round(System::Drawing::RectangleF value);

public static System.Drawing.Rectangle Round (System.Drawing.RectangleF value);

static member Round : System.Drawing.RectangleF -> System.Drawing.Rectangle

Public Shared Function Round (value As RectangleF) As Rectangle

매개 변수

value

RectangleF

변환될 RectangleF입니다.

반환

Rectangle

Rectangle을(를) 반올림한 정수 값입니다.

예제

다음 코드 예제를 사용 Round 하는 방법을 보여 줍니다는 및 Truncate 메서드. 이 예제는 Windows Form에서 사용하도록 설계되었습니다. 양식에 이 코드를 붙여넣고 양식의 Paint 이벤트를 처리할 때 메서드를 호출 RoundingAndTruncatingRectangles 하여 으로 PaintEventArgs전달 e 합니다.
