# Rect.op_Inequality Method

.NET Framework 3.0
Compares two rectangles for inequality.

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

## Syntax

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

#### Parameters

rect1

The first rectangle to compare.

rect2

The second rectangle to compare.

#### Return Value

true if the two rectangles do not have the same Location and Size; otherwise, false.

## Remarks

This operation tests for object inequality.

In this comparison, NaN is not considered equal to itself.

Note:

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

## Example

The following example shows how to use the op_Inequality method to determine if two rectangles are 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;

}

```
