Rect.Equals Method (Rect)

Indicates whether the specified rectangle is equal to the current rectangle.

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

public bool Equals(
	Rect value
)

Parameters

value
Type: System.Windows.Rect

The rectangle to compare to the current rectangle.

Return Value

Type: System.Boolean
true if the specified rectangle has the same Location and Size values as the current rectangle; otherwise, false.

This operation tests for object equality.

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 Equals(Rect) method to determine if a rectangle is equal to a specified rectangle.

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;

}
