Rectangle.IntersectsWith(Rectangle) 方法

定義

判斷這個矩形是否與 rect 交集。

public:
 bool IntersectsWith(System::Drawing::Rectangle rect);
public readonly bool IntersectsWith (System.Drawing.Rectangle rect);
public bool IntersectsWith (System.Drawing.Rectangle rect);
member this.IntersectsWith : System.Drawing.Rectangle -> bool
Public Function IntersectsWith (rect As Rectangle) As Boolean

參數

rect
Rectangle

要測試的矩形。

傳回

如果有任何交集,則這個方法會傳回 true,否則傳回 false

範例

下列程式代碼範例示範 IntersectIsEmptyIntersectsWith 成員。 此範例應該與 Windows Form 搭配使用。 將此程式代碼貼到表單中,並在處理表單的事件 Paint 時呼叫此方法,並傳遞 ePaintEventArgs

private:
   void InstanceRectangleIntersection( PaintEventArgs^ e )
   {
      Rectangle rectangle1 = Rectangle(50,50,200,100);
      Rectangle rectangle2 = Rectangle(70,20,100,200);
      e->Graphics->DrawRectangle( Pens::Black, rectangle1 );
      e->Graphics->DrawRectangle( Pens::Red, rectangle2 );
      if ( rectangle1.IntersectsWith( rectangle2 ) )
      {
         rectangle1.Intersect( rectangle2 );
         if (  !rectangle1.IsEmpty )
         {
            e->Graphics->FillRectangle( Brushes::Green, rectangle1 );
         }
      }
   }
private void InstanceRectangleIntersection(PaintEventArgs e)
{

    Rectangle rectangle1 = new Rectangle(50, 50, 200, 100);
    Rectangle rectangle2 = new Rectangle(70, 20, 100, 200);

    e.Graphics.DrawRectangle(Pens.Black, rectangle1);
    e.Graphics.DrawRectangle(Pens.Red, rectangle2);

    if (rectangle1.IntersectsWith(rectangle2))
    {
        rectangle1.Intersect(rectangle2);
        if (!rectangle1.IsEmpty)
        {
            e.Graphics.FillRectangle(Brushes.Green, rectangle1);
        }
    }
}
  Private Sub InstanceRectangleIntersection( _
      ByVal e As PaintEventArgs)

      Dim rectangle1 As New Rectangle(50, 50, 200, 100)
      Dim rectangle2 As New Rectangle(70, 20, 100, 200)

      e.Graphics.DrawRectangle(Pens.Black, rectangle1)
      e.Graphics.DrawRectangle(Pens.Red, rectangle2)

      If (rectangle1.IntersectsWith(rectangle2)) Then
          rectangle1.Intersect(rectangle2)
          If Not (rectangle1.IsEmpty) Then
              e.Graphics.FillRectangle(Brushes.Green, rectangle1)
          End If
      End If
  End Sub
