Testar om två RectangleF strukturer har samma plats och storlek.

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

Parametrar

left
RectangleF

Strukturen RectangleF till vänster om likhetsoperatorn.

right
RectangleF

Den RectangleF struktur som är till höger om likhetsoperatorn.

Returer

Boolean

trueom de två angivna RectangleF strukturerna har lika med X, Y, Widthoch Height egenskaper, annars . false

Exempel

I följande kodexempel visas hur du använder Implicitmedlemmarna , RectangleFoch Equality . Det här exemplet är utformat för användning med ett Windows formulär. Klistra in den här koden i ett formulär och anropa ConvertRectangleToRectangleF metoden när du hanterar formulärets Paint händelse och skicka e som 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)

    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()
