Rect.Empty Property

Gets a special value that represents a rectangle with no position or area.

Namespace:  System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

public static Rect Empty { get; }

Property Value

Type: System.Windows.Rect
The empty rectangle, which has X and Y property values of PositiveInfinity, and has Width and Height property values of NegativeInfinity.

Avoid mathematical computations involving empty rectangles. Because both X and Y are infinite values, processor operations are severely impaired by these operations. Comparisons involving these values will not affect application performance.
