Rect.Inequality(Rect, Rect) 演算子

定義

2 つの四角形を比較し、等しくないかどうかを判断します。Compares two rectangles for inequality.

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

パラメーター

rect1
Rect

最初に比較する四角形。The first rectangle to compare.

rect2
Rect

2 番目に比較する四角形。The second rectangle to compare.

戻り値

Boolean

四角形が同じ Location 値と Size 値を持たない場合は true。それ以外の場合は falsetrue if the rectangles do not have the same Location and Size values; otherwise, false.

次の例は、演算子を使用して、 Inequality 2 つの四角形が正確に等しくないかどうかを判断する方法を示しています。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

注釈

この操作では、オブジェクトが等しくないかどうかをテストします。This operation tests for object inequality.

この比較では、の2つのインスタンス Double.NaN が等しいと見なされます。In this comparison, two instances of Double.NaN are considered equal.

注意

四角形の位置と大きさは、値によって示され Double ます。A rectangle's position and dimensions are described by Double values. Double値が有効になると、値の精度が失われる可能性があるため、論理的に等しい2つの値の比較は失敗する可能性があります。Because Double values can lose precision when operated upon, a comparison between two values that are logically equal might fail.

この演算子の同等の方法は次のようになります。 Rect.Equals(Rect, Rect)The equivalent method for this operator is Rect.Equals(Rect, Rect)
