Size.Equality(Size, Size) Operator

Definition

Namespace:

System.Drawing

Assemblies:

netstandard.dll, System.Drawing.Primitives.dll

Source:

Size.cs

Tests whether two Size structures are equal.

C#

public static bool operator ==(System.Drawing.Size sz1, System.Drawing.Size sz2);

Parameters

sz1

Size

The Size structure on the left side of the equality operator.

sz2

Size

The Size structure on the right of the equality operator.

Returns

Boolean

true if sz1 and sz2 have equal width and height; otherwise, false.

Examples

The following code example creates points and sizes by using several of the overloaded operators defined for these types. It also demonstrates how to use the SystemPens class.

This example is designed to be used with Windows Forms. Create a form that contains a Button named subtractButton. Paste the code into the form and call the CreatePointsAndSizes method from the form's Paint event-handling method, passing e as PaintEventArgs.

C#

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);
    }
}
