Point.Equality(Point, Point) Operatore

Definizione

Confronta due oggetti Point.Compares two Point objects. Il risultato specifica se i valori delle proprietà X e Y dei due oggetti Point sono uguali.The result specifies whether the values of the X and Y properties of the two Point objects are equal.

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

Parametri

Esempio

Nell'esempio di codice riportato di seguito viene illustrato come utilizzare l' Equality operatore e come costruire un oggetto Point da un Size o due Integer.The following code example demonstrates how to use the Equality operator and how to construct a Point from a Size or two integers. Viene inoltre illustrato come utilizzare le X proprietà e Y .It also demonstrates how to use the X and Y properties. Questo esempio è progettato per essere usato con Windows Form.This example is designed to be used with Windows Forms. Incollare il codice in un form che contiene un pulsante denominato Button1 e associare il Button1_Click metodo all'evento del pulsante Click .Paste the code into a form that contains a button named Button1, and associate the Button1_Click method with the button's Click event.

private:
   void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      // Construct a new Point with integers.
      Point Point1 = Point(100,100);

      // Create a Graphics object.
      Graphics^ formGraphics = this->CreateGraphics();

      // Construct another Point, this time using a Size.
      Point Point2 = Point(System::Drawing::Size( 100, 100 ));

      // Call the equality operator to see if the points are equal,  
      // and if so print out their x and y values.
      if ( Point1 == Point2 )
      {
         array<Object^>^temp0 = {Point1.X,Point2.X,Point1.Y,Point2.Y};
         formGraphics->DrawString( String::Format( "Point1.X: "
         "{0},Point2.X: {1}, Point1.Y: {2}, Point2.Y {3}", temp0 ), this->Font, Brushes::Black, PointF(10,70) );
      }
   }
private void Button1_Click(System.Object sender, System.EventArgs e)
{

    // Construct a new Point with integers.
    Point Point1 = new Point(100, 100);

    // Create a Graphics object.
    Graphics formGraphics = this.CreateGraphics();

    // Construct another Point, this time using a Size.
    Point Point2 = new Point(new Size(100, 100));

    // Call the equality operator to see if the points are equal,  
    // and if so print out their x and y values.
    if (Point1 == Point2)
    {
        formGraphics.DrawString(String.Format("Point1.X: " +
            "{0},Point2.X: {1}, Point1.Y: {2}, Point2.Y {3}",
            new object[]{Point1.X, Point2.X, Point1.Y, Point2.Y}),
            this.Font, Brushes.Black, new PointF(10, 70));
    }
}
Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click

    ' Construct a new Point with integers.
    Dim Point1 As New Point(100, 100)

    ' Create a Graphics object.
    Dim formGraphics As Graphics = Me.CreateGraphics()

    ' Construct another Point, this time using a Size.
    Dim Point2 As New Point(New Size(100, 100))

    ' Call the equality operator to see if the points are equal,  
    ' and if so print out their x and y values.
    If (Point.op_Equality(Point1, Point2)) Then
        formGraphics.DrawString(String.Format("Point1.X: " & _
            "{0},Point2.X: {1}, Point1.Y: {2}, Point2.Y {3}", _
            New Object() {Point1.X, Point2.X, Point1.Y, Point2.Y}), _
            Me.Font, Brushes.Black, New PointF(10, 70))
