Size.Equality(Size, Size) Operator

Definition

Überprüft, ob zwei Size-Strukturen gleich sind.Tests whether two Size structures are equal.

public:
 static bool operator ==(System::Drawing::Size sz1, System::Drawing::Size sz2);
public static bool operator == (System.Drawing.Size sz1, System.Drawing.Size sz2);
static member ( = ) : System.Drawing.Size * System.Drawing.Size -> bool
Public Shared Operator == (sz1 As Size, sz2 As Size) As Boolean

Parameter

sz1
Size

Die Size-Struktur auf der linken Seite des Gleichheitsoperators.The Size structure on the left side of the equality operator.

sz2
Size

Die Size-Struktur auf der rechten Seite des Gleichheitsoperators.The Size structure on the right of the equality operator.

Gibt zurück

true, wenn sz1 und sz2 dieselbe Breite und Höhe aufweisen, andernfalls false.true if sz1 and sz2 have equal width and height; otherwise, false.

Beispiele

Das folgende Codebeispiel erstellt Punkte und Größen mithilfe mehrerer der überladenen Operatoren, die für diese Typen definiert sind.The following code example creates points and sizes by using several of the overloaded operators defined for these types. Außerdem wird die Verwendung der SystemPens -Klasse veranschaulicht.It also demonstrates how to use the SystemPens class.

Dieses Beispiel ist für die Verwendung mit Windows Forms konzipiert.This example is designed to be used with Windows Forms. Erstellen Sie ein Formular, das Button ein subtractButtonmit dem Namen enthält.Create a form that contains a Button named subtractButton. Fügen Sie den Code in das Formular ein, CreatePointsAndSizes und wenden Sie die- Paint Methode aus der Ereignis Behandlungsmethode e des PaintEventArgsFormulars an, indem Sie als übergeben.Paste the code into the form and call the CreatePointsAndSizes method from the form's Paint event-handling method, passing e as PaintEventArgs.

void CreatePointsAndSizes( PaintEventArgs^ e )
{
   // Create the starting point.
   Point startPoint = Point(subtractButton->Size);
   
   // Use the addition operator to get the end point.
   Point endPoint = startPoint + System::Drawing::Size( 140, 150 );
   
   // Draw a line between the points.
   e->Graphics->DrawLine( SystemPens::Highlight, startPoint, endPoint );
   
   // Convert the starting point to a size and compare it to the
   // subtractButton size.  
   System::Drawing::Size buttonSize = (System::Drawing::Size)startPoint;
   if ( buttonSize == subtractButton->Size )
   {
      e->Graphics->DrawString( "The sizes are equal.", gcnew System::Drawing::Font( this->Font,FontStyle::Italic ), Brushes::Indigo, 10.0F, 65.0F );
   }
