Rectangle.IntersectsWith(Rectangle) 方法

定義

命名空間:
System.Drawing
組件:
System.Drawing.Primitives.dll
組件:
System.Drawing.dll
組件:
netstandard.dll

判斷這個矩形是否與 rect 交集。Determines if this rectangle intersects with rect.

public:
 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。The rectangle to test.

傳回

Boolean

如果有任何交集，則這個方法會傳回 true，否則傳回 false。This method returns true if there is any intersection, otherwise false.

範例

下列程式碼範例會示範 Intersect IsEmpty 和 IntersectsWith 成員。The following code example demonstrates the Intersect, IsEmpty and the IntersectsWith members. 此範例應搭配 Windows Form 使用。This example should be used with a Windows Form. 將此程式碼貼到表單中，並在處理表單的事件時呼叫這個方法 Paint ，傳遞 e 為 PaintEventArgs 。Paste this code into a form and call this method when handling the form's Paint event, passing e as 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
