RectangleF.Equality Operator (RectangleF, RectangleF)

 

Tests whether two RectangleF structures have equal location and size.

Namespace:   System.Drawing
Assembly:  System.Drawing (in System.Drawing.dll)

public static bool operator ==(
	RectangleF left,
	RectangleF right
)

Parameters

left
Type: System.Drawing.RectangleF

The RectangleF structure that is to the left of the equality operator.

right
Type: System.Drawing.RectangleF

The RectangleF structure that is to the right of the equality operator.

Return Value

Type: System.Boolean

This operator returns true if the two specified RectangleF structures have equal X, Y, Width, and Height properties.

The following code example demonstrates how to use the Implicit(Rectangle to RectangleF), RectangleFand Equality members. This example is designed for use with a Windows Form. Paste this code into a form and call the ConvertRectangleToRectangleF method when handling the form's Paint event, passing e as PaintEventArgs.

private void ConvertRectangleToRectangleF(PaintEventArgs e)
{

    // Create a rectangle.
    Rectangle rectangle1 = new Rectangle(30, 40, 50, 100);

    // Convert it to a RectangleF.
    RectangleF convertedRectangle = rectangle1;

    // Create a new RectangleF.
    RectangleF rectangle2 = new RectangleF(new PointF(30.0F, 40.0F),
        new SizeF(50.0F, 100.0F));

    // Create a custom, partially transparent brush.
    SolidBrush redBrush = new SolidBrush(Color.FromArgb(40, Color.Red));

    // Compare the converted rectangle with the new one.  If they 
    // are equal draw and fill the rectangles on the form.
    if (convertedRectangle == rectangle2)
    {
        e.Graphics.FillRectangle(redBrush, rectangle2);
    }

    // Dispose of the custom brush.
    redBrush.Dispose();
}
