Point.Addition(Point, Size) Point.Addition(Point, Size) Point.Addition(Point, Size) Point.Addition(Point, Size) Operator

定義

根據指定的 Point 來轉換 SizeTranslates a Point by a given Size.

public:
 static System::Drawing::Point operator +(System::Drawing::Point pt, System::Drawing::Size sz);
public static System.Drawing.Point operator + (System.Drawing.Point pt, System.Drawing.Size sz);
static member ( + ) : System.Drawing.Point * System.Drawing.Size -> System.Drawing.Point
Public Shared Operator + (pt As Point, sz As Size) As Point

參數

pt
Point Point Point Point

要轉換的 PointThe Point to translate.

sz
Size Size Size Size

Size,指定要加入至 pt 座標的數字配對。A Size that specifies the pair of numbers to add to the coordinates of pt.

傳回

轉譯的 PointThe translated Point.

範例

下列程式碼範例會使用為這些類型定義的數個多載運算子, 來建立點和大小。The following code example creates points and sizes using several of the overloaded operators defined for these types. 它也會示範如何使用SystemPens類別。It also demonstrates how to use the SystemPens class.

這個範例是設計來與 Windows Forms 搭配使用。This example is designed to be used with Windows Forms. 建立包含名為Button subtractButton的表單。Create a form that contains a Button named subtractButton. 將程式碼貼入表單, 並從CreatePointsAndSizes表單的Paint事件處理方法呼叫方法, 並以e PaintEventArgs傳遞。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 );
   }
}
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))

    ' 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.  
    Dim buttonSize As Size = Point.op_Explicit(startPoint)
    If (Size.op_Equality(buttonSize, subtractButton.Size)) Then

        ' If the sizes are equal, tell the user.
        e.Graphics.DrawString("The sizes are equal.", _
            New Font(Me.Font, FontStyle.Italic), _
            Brushes.Indigo, 10.0F, 65.0F)
    End If

End Sub
