Rectangle.IntersectsWith(Rectangle) 方法

定義

命名空間:

System.Drawing

組件:

System.Drawing.Primitives.dll

來源:

Rectangle.cs

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);

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

Boolean

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 Intersect、 IsEmpty 和 IntersectsWith 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 e 為 PaintEventArgs。

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
