Vector.Inequality(Vector, Vector) Operator

Definition

Namespace:

System.Windows

Assembly:

WindowsBase.dll

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

Parameters

vector1

Vector

The first vector to compare.

vector2

Vector

The second vector to compare.

Returns

Boolean

true if the X and Y components of vector1 and vector2 are different; otherwise, false.

Examples

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

Remarks

A vector's X and Y properties are described using Double values. 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.
