Rect.Equals Method (Rect, Rect)


Indicates whether the specified rectangles are equal.

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

public static bool Equals(
	Rect rect1,
	Rect rect2


Type: System.Windows.Rect

The first rectangle to compare.

Type: System.Windows.Rect

The second rectangle to compare.

Return Value

Type: System.Boolean

true if the rectangles have the same Location and Size values; otherwise, false.

This operation tests for object equality.

In this comparison, two instances of Double.NaN are considered equal.


A rectangle's position and dimensions are described by Double values. Because Double values can lose precision when operated upon, a comparison between two values that are logically equal might fail.

The following example shows how to use the Equals(Rect, Rect) method to determine if one rectangle is equal to another.

private bool rectEqualsExample2()
    // Create a rectangle.
    Rect myRectangle1 = new Rect();

    // The Location property specifies the coordinates of the upper left-hand 
    // corner of the rectangle. 
    myRectangle1.Location = new Point(10, 5);

    // Set the Size property of the rectangle with a width of 200
    // and a height of 50.
    myRectangle1.Size = new Size(200, 50);

    // Create second rectangle to compare to the first.
    Rect myRectangle2 = new Rect();
    myRectangle2.Location = new Point(10, 5);
    myRectangle2.Size = new Size(200, 50);

    // Using the Equals method, see if the second rectangle is 
    // the same as the first rectangle. doesEqual is true because
    // both rectangles are exactly the same in that they both have the 
    // same location and size.
    bool doesEqual = Rect.Equals(myRectangle1, myRectangle2);

    return doesEqual;
