Size.Equality(Size, Size) Operator

Definisi

Ruang nama:

System.Drawing

Rakitan:

System.Drawing.Primitives.dll

Sumber:

Size.cs

Menguji apakah dua Size struktur sama.

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

Struktur Size di sisi kiri operator kesetaraan.

sz2

Size

Struktur Size di sebelah kanan operator kesetaraan.

Mengembalikan

Boolean

true jika sz1 dan sz2 memiliki lebar dan tinggi yang sama; jika tidak, false.

Contoh

Contoh kode berikut membuat titik dan ukuran dengan menggunakan beberapa operator yang kelebihan beban yang ditentukan untuk jenis ini. Ini juga menunjukkan cara menggunakan SystemPens kelas .

Contoh ini dirancang untuk digunakan dengan Formulir Windows. Create formulir yang berisi bernama ButtonsubtractButton. Tempelkan kode ke dalam formulir dan panggil CreatePointsAndSizes metode dari metode penanganan peristiwa formulir Paint , meneruskan e sebagai 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 );
   }
}

private void CreatePointsAndSizes(PaintEventArgs e)
{

    // Create the starting point.
    Point startPoint = new Point(subtractButton.Size);

    // Use the addition operator to get the end point.
    Point endPoint = startPoint + new 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.  
    Size buttonSize = (Size)startPoint;
    if (buttonSize == subtractButton.Size)

        // If the sizes are equal, tell the user.
    {
        e.Graphics.DrawString("The sizes are equal.", 
            new Font(this.Font, FontStyle.Italic), 
            Brushes.Indigo, 10.0F, 65.0F);
    }
}

Private Sub CreatePointsAndSizes(ByVal e As PaintEventArgs)

    ' Create the starting point.
    Dim startPoint As New Point(subtractButton.Size)

    ' Use the addition operator to get the end point.
    Dim endPoint As Point = Point.op_Addition(startPoint, _
        New Size(140, 150))
