Rect.Inequality Operator

Compares two rectangles for inequality.

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

public static bool operator !=(
	Rect rect1,
	Rect rect2
)
You cannot use methods in XAML.

Parameters

rect1
Type: System.Windows.Rect

The first rectangle to compare.

rect2
Type: System.Windows.Rect

The second rectangle to compare.

Return Value

Type: System.Boolean
true if the rectangles do not have the same Location and Size values; otherwise, false.

This operation tests for object inequality.

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

NoteNote:

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 Inequality operator to determine if two rectangles are not exactly equal.

private Boolean overloadedInequalityOperatorExample()
{
    // Initialize new rectangle.
    Rect myRectangle = new Rect();

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

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

    // Create second rectangle to compare to the first.
    Rect myRectangle2 = new Rect();
    myRectangle2.Location = new Point(0, 0);
    myRectangle2.Size = new Size(200, 50);

    // Check if the two Rects are not equal using the overloaded inequality operator. 
    // notEqual is true because although the size of each rectangle is the same, 
    // the locations are different. 
    bool notEqual = (myRectangle != myRectangle2);

    // Returns true. 
    return notEqual;

}
