Indicates whether two rectangles are equal.
Overloads
| Equals(Rect, Rect) |
Indicates whether the specified rectangles are equal. |
| Equals(Object) |
Indicates whether the specified object is equal to the current rectangle. |
| Equals(Rect) |
Indicates whether the specified rectangle is equal to the current rectangle. |
Equals(Rect, Rect)
Indicates whether the specified rectangles are equal.
public:
static bool Equals(System::Windows::Rect rect1, System::Windows::Rect rect2);public static bool Equals (System.Windows.Rect rect1, System.Windows.Rect rect2);static member Equals : System.Windows.Rect * System.Windows.Rect -> boolPublic Shared Function Equals (rect1 As Rect, rect2 As Rect) As BooleanParameters
- rect1
- Rect
The first rectangle to compare.
- rect2
- Rect
The second rectangle to compare.
Returns
true if the rectangles have the same Location and Size values; otherwise, false.
Examples
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;
}
Remarks
This operation tests for object equality.
In this comparison, two instances of Double.NaN are considered equal.
Note
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.

Equals(Object)
Indicates whether the specified object is equal to the current rectangle.
public:
override bool Equals(System::Object ^ o);public override bool Equals (object o);override this.Equals : obj -> boolPublic Overrides Function Equals (o As Object) As BooleanParameters
- o
- Object
The object to compare to the current rectangle.
Returns
true if o is a Rect and has the same Location and Size values as the current rectangle; otherwise, false.
Examples
The following example shows how to use the Equals(Object) method to determine if a rectangle is equal to a specified object.
private bool rectEqualsExample1()
{
// 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 with respect to location and size.
bool doesEqual = myRectangle1.Equals(myRectangle2);
return doesEqual;
