Point.Equality(Point, Point) Point.Equality(Point, Point) Point.Equality(Point, Point) Point.Equality(Point, Point) Operator

定義

2 つの Point 構造体を比較して、等しいかどうかを確認します。Compares two Point structures for equality.

public:
 static bool operator ==(System::Windows::Point point1, System::Windows::Point point2);
public static bool operator == (System.Windows.Point point1, System.Windows.Point point2);
static member ( = ) : System.Windows.Point * System.Windows.Point -> bool
Public Shared Operator == (point1 As Point, point2 As Point) As Boolean

パラメーター

point1
Point Point Point Point

最初に比較する Point 構造体。The first Point structure to compare.

point2
Point Point Point Point

比較する 2 番目の Point 構造体。The second Point structure to compare.

戻り値

point1 および point2X 座標と Y 座標が等しい場合は true。それ以外の場合は falsetrue if both the X and Y coordinates of point1 and point2 are equal; otherwise, false.

オーバーロードされた (= =) 演算子Pointを使用して2つの構造体が等しいかどうかを確認する方法を次の例に示します。The following example shows how to check if two Point structures are equal using the overloaded (==) operator.

private Boolean overloadedEqualityOperatorExample()
{
    Point point1 = new Point(10, 5);
    Point point2 = new Point(15, 40);

    // Check if two Points are equal using the overloaded equality operator.
    // areEqual is False.
    Boolean areEqual = (point1 == point2);

    return areEqual;

}
Private Function overloadedEqualityOperatorExample() As Boolean
	Dim point1 As New Point(10, 5)
	Dim point2 As New Point(15, 40)

	' Check if two Points are equal using the overloaded equality operator.
	' areEqual is False.
	Dim areEqual As Boolean = (point1 = point2)

	Return areEqual

End Function

注釈

ポイントの座標は、値をDouble使用して記述されます。A point's coordinates are described using Double values. Double値は算術演算を実行するときに有効桁数を失う可能性があるため、 Point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 the value of Double can lose precision when arithmetic operations are performed on them, a comparison between two Point values that are logically equal might fail.
