Vector.Inequality(Vector, Vector) 演算子

定義

2 つのベクターを比較して、等しくないかどうかを判断します。Compares two vectors for inequality.

public:
 static bool operator !=(System::Windows::Vector vector1, System::Windows::Vector vector2);
public static bool operator != (System.Windows.Vector vector1, System.Windows.Vector vector2);
static member op_Inequality : System.Windows.Vector * System.Windows.Vector -> bool
Public Shared Operator != (vector1 As Vector, vector2 As Vector) As Boolean

パラメーター

vector1
Vector

比較する最初のベクトル。The first vector to compare.

vector2
Vector

比較する 2 番目のベクトル。The second vector to compare.

戻り値

vector1vector2X および Y コンポーネントが異なる場合は true。それ以外の場合は falsetrue if the X and Y components of vector1 and vector2 are different; otherwise, false.

次の例では、この演算子 (! =) を使用して、 Vector 2 つの構造体が等しくないかどうかを確認する方法を示します。The following example shows how to use this operator (!=) to check whether two Vector structures are not equal.

private Boolean overloadedInequalityOperatorExample()
{
    Vector vector1 = new Vector(20, 30);
    Vector vector2 = new Vector(45, 70);
    Boolean areNotEqual;

    // Check whether the two Vectors are not equal, using the overloaded 
    // inequality operator.
    // areNotEqual is True.
    areNotEqual = (vector1 != vector2);

    return areNotEqual;

}
Private Function overloadedInequalityOperatorExample() As Boolean
    Dim vector1 As New Vector(20, 30)
    Dim vector2 As New Vector(45, 70)
    Dim areNotEqual As Boolean

    ' Check whether the two Vectors are not equal, using the overloaded 
    ' inequality operator.
    ' areNotEqual is True.
    areNotEqual = (vector1 <> vector2)

    Return areNotEqual

End Function

注釈

ベクターのXプロパティとYプロパティは、値Doubleを使用して記述されます。A vector's X and Y properties are described using Double values. Double値は算術演算が実行されると有効桁数が失われる可能性があるため、 Vector論理的に等しい2つの構造体の比較は失敗する可能性があります。Because the value of a Double can lose precision when arithmetic operations are performed on it, a comparison between two Vector structures that are logically equal might fail.
