정의

네임스페이스:

Source:

Point.cs

지정된 Point 구조를 구조체로 Size 변환합니다.

public:
 static explicit operator System::Drawing::Size(System::Drawing::Point p);

public static explicit operator System.Drawing.Size(System.Drawing.Point p);

static member op_Explicit : System.Drawing.Point -> System.Drawing.Size

Public Shared Narrowing Operator CType (p As Point) As Size

매개 변수

p

Point

Point 변환할 수 있습니다.

반품

Size

Size 변환의 결과입니다.

예제

다음 코드 예제에서는 이러한 형식에 대해 정의된 여러 오버로드된 연산자를 사용하여 점과 크기를 만듭니다. 또한 클래스를 사용하는 방법을 보여 줍니다 SystemPens .

이 예제는 Windows Forms와 함께 사용하도록 설계되었습니다. 이름이 Button지정된 폼을 subtractButton 만듭니다. 코드를 양식에 붙여넣고 양식의 CreatePointsAndSizes 이벤트 처리 메서드에서 메서드를 호출 Paint 하여 다음과 같이 e전달 PaintEventArgs 합니다.

void CreatePointsAndSizes( PaintEventArgs^ e )
{
   // Create the starting point.
   Point startPoint = Point(subtractButton->Size);
   
   // Use the addition operator to get the end point.
   Point endPoint = startPoint + System::Drawing::Size( 140, 150 );
   
   // Draw a line between the points.
   e->Graphics->DrawLine( SystemPens::Highlight, startPoint, endPoint );
   
   // Convert the starting point to a size and compare it to the
   // subtractButton size.  
   System::Drawing::Size buttonSize = (System::Drawing::Size)startPoint;
   if ( buttonSize == subtractButton->Size )
   {
      e->Graphics->DrawString( "The sizes are equal.", gcnew System::Drawing::Font( this->Font,FontStyle::Italic ), Brushes::Indigo, 10.0F, 65.0F );
   }
