new System.Drawing.Point : System.Drawing.Size -> System.Drawing.Point

Public Sub New (sz As Size)

Parameter

sz: Size

Size yang menentukan koordinat untuk yang baruPoint.

Contoh

Contoh kode berikut menunjukkan cara menggunakan Equality operator dan cara membuat Point dari satu Size atau dua bilangan bulat. Ini juga menunjukkan cara menggunakan X properti dan Y . Contoh ini dirancang untuk digunakan dengan Formulir Windows. Tempelkan kode ke dalam formulir yang berisi tombol bernama Button1, dan kaitkan Button1_Click metode dengan peristiwa tombol Click .

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))
    End If

Contoh

Contoh kode berikut menunjukkan cara menggunakan Point konstruktor dan Size.Size dan System.Drawing.ContentAlignment enumerasi. Untuk menjalankan contoh ini, tempelkan kode ini ke dalam Formulir Windows yang berisi label bernama Label1, dan panggil InitializeLabel1 metode dalam konstruktor formulir.

void InitializeLabel1()
{
   // Set a border.
   Label1->BorderStyle = BorderStyle::FixedSingle;
   
   // Set the size, constructing a size from two integers.
   Label1->Size = System::Drawing::Size( 100, 50 );
   
   // Set the location, constructing a point from a 32-bit integer
   // (using hexadecimal).
   Label1->Location = Point(0x280028);
   
   // Set and align the text on the lower-right side of the label.
   Label1->TextAlign = ContentAlignment::BottomRight;

    // (using hexadecimal).
    Label1.Location = new Point(0x280028);

    // Set and align the text on the lower-right side of the label.
    Label1.TextAlign = ContentAlignment.BottomRight;
    Label1.Text = "Bottom Right Alignment";
}

Private Sub InitializeLabel1()

    ' Set a border.
    Label1.BorderStyle = BorderStyle.FixedSingle

    ' Set the size, constructing a size from two integers.
    Label1.Size = New Size(100, 50)

    ' Set the location, constructing a point from a 32-bit integer
    ' (using hexadecimal).
    Label1.Location = New Point(&H280028)

    ' Set and align the text on the lower-right side of the label.
    Label1.TextAlign = ContentAlignment.BottomRight
    Label1.Text = "Bottom Right Alignment"
