public:
 static bool operator !=(System::Windows::Rect rect1, System::Windows::Rect rect2);
public static bool operator != (System.Windows.Rect rect1, System.Windows.Rect rect2);
static member op_Inequality : System.Windows.Rect * System.Windows.Rect -> bool
Public Shared Operator != (rect1 As Rect, rect2 As Rect) As Boolean

Parametri

rect1
Rect Rect Rect Rect

Primo rettangolo da confrontare.The first rectangle to compare.

rect2
Rect Rect Rect Rect

Secondo rettangolo da confrontare.The second rectangle to compare.

Restituisce

true se i rettangoli non hanno gli stessi valori Location e Size; in caso contrario, false.true if the rectangles do not have the same Location and Size values; otherwise, false.

Esempi

Nell'esempio seguente viene illustrato come utilizzare l' Inequality operatore per determinare se due rettangoli non sono esattamente uguali.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;

}
Private Function overloadedInequalityOperatorExample() As Boolean
	' Initialize new rectangle.
	Dim myRectangle As 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.
	Dim myRectangle2 As 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.
	Dim notEqual As Boolean = (myRectangle <> myRectangle2)

	' Returns true.
	Return notEqual

End Function

Commenti

Questa operazione verifica la disuguaglianza degli oggetti.This operation tests for object inequality.

In questo confronto, due istanze di Double.NaN sono considerate uguali.In this comparison, two instances of Double.NaN are considered equal.

Nota

La posizione e le dimensioni di un rettangolo sono Double descritte dai valori.A rectangle's position and dimensions are described by Double values. Poiché Double i valori possono perdere precisione quando vengono usati, un confronto tra due valori logicamente uguali potrebbe non riuscire.Because Double values can lose precision when operated upon, a comparison between two values that are logically equal might fail.

Il metodo equivalente per questo operatore èRect.Equals(Rect, Rect)The equivalent method for this operator is Rect.Equals(Rect, Rect)
