RectangleF.Equality(RectangleF, RectangleF) RectangleF.Equality(RectangleF, RectangleF) RectangleF.Equality(RectangleF, RectangleF) RectangleF.Equality(RectangleF, RectangleF) Operator

Definition

Tests whether two RectangleF structures have equal location and size.

public:
 static bool operator ==(System::Drawing::RectangleF left, System::Drawing::RectangleF right);
public static bool operator == (System.Drawing.RectangleF left, System.Drawing.RectangleF right);
static member ( = ) : System.Drawing.RectangleF * System.Drawing.RectangleF -> bool
Public Shared Operator == (left As RectangleF, right As RectangleF) As Boolean

Parameters

left
RectangleF RectangleF RectangleF RectangleF

The RectangleF structure that is to the left of the equality operator.

right
RectangleF RectangleF RectangleF RectangleF

The RectangleF structure that is to the right of the equality operator.

Returns

true if the two specified RectangleF structures have equal X, Y, Width, and Height properties; otherwise, false.

Examples

The following code example demonstrates how to use the Implicit, RectangleF and Equality members. This example is designed for use with a Windows Form. Paste this code into a form and call the ConvertRectangleToRectangleF method when handling the form's Paint event, passing e as PaintEventArgs.

private:
   void ConvertRectangleToRectangleF( PaintEventArgs^ e )
   {
      // Create a rectangle.
      Rectangle rectangle1 = Rectangle(30,40,50,100);

      // Convert it to a RectangleF.
      RectangleF convertedRectangle = rectangle1;

      // Create a new RectangleF.
      RectangleF rectangle2 = RectangleF(PointF(30.0F,40.0F),SizeF(50.0F,100.0F));

      // Create a custom, partially transparent brush.
      SolidBrush^ redBrush = gcnew SolidBrush( Color::FromArgb( 40, Color::Red ) );

      // Compare the converted rectangle with the new one.  If they 
      // are equal draw and fill the rectangles on the form.
      if ( convertedRectangle == rectangle2 )
      {
         e->Graphics->FillRectangle( redBrush, rectangle2 );
      }

      // Dispose of the custom brush.
      delete redBrush;
   }
};
private void ConvertRectangleToRectangleF(PaintEventArgs e)
{

    // Create a rectangle.
    Rectangle rectangle1 = new Rectangle(30, 40, 50, 100);

    // Convert it to a RectangleF.
    RectangleF convertedRectangle = rectangle1;

    // Create a new RectangleF.
    RectangleF rectangle2 = new RectangleF(new PointF(30.0F, 40.0F),
        new SizeF(50.0F, 100.0F));

    // Create a custom, partially transparent brush.
    SolidBrush redBrush = new SolidBrush(Color.FromArgb(40, Color.Red));

    // Compare the converted rectangle with the new one.  If they 
    // are equal draw and fill the rectangles on the form.
    if (convertedRectangle == rectangle2)
    {
        e.Graphics.FillRectangle(redBrush, rectangle2);
    }

    // Dispose of the custom brush.
    redBrush.Dispose();
}

Private Sub ConvertRectangleToRectangleF( _
    ByVal e As PaintEventArgs)

    ' Create a rectangle.
    Dim rectangle1 As New Rectangle(30, 40, 50, 100)

    ' Convert it to a RectangleF.
    Dim convertedRectangle As RectangleF = _
        RectangleF.op_Implicit(rectangle1)

    ' Create a new RectangleF.
    Dim rectangle2 As New RectangleF(New PointF(30.0F, 40.0F), _
        New SizeF(50.0F, 100.0F))

    ' Create a custom, partially transparent brush.
    Dim redBrush As New SolidBrush(Color.FromArgb(40, Color.Red))

    ' Compare the converted rectangle with the new one.  If they 
    ' are equal, draw and fill the rectangles on the form.
    If (RectangleF.op_Equality(convertedRectangle, rectangle2)) Then
        e.Graphics.FillRectangle(redBrush, rectangle2)
    End If

    ' Dispose of the custom brush.
    redBrush.Dispose()
End Sub
