Vector.Equality(Vector, Vector) Operator

Definition

Compares two vectors for equality.

C#
public static bool operator ==(System.Windows.Vector vector1, System.Windows.Vector vector2);

Parameters

vector1
Vector

The first vector to compare.

vector2
Vector

The second vector to compare.

Returns

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

Examples

The following example shows how to use this operator (==) to check whether two Vector structures are equal.

C#
private Boolean overloadedEqualityOperatorExample()
{
    Vector vector1 = new Vector(20, 30);
    Vector vector2 = new Vector(45, 70);

    // If the two vectors are equal, areEqual is True,
    // otherwise it is False. In this example it is False.
    Boolean areEqual = (vector1 == vector2);

    return areEqual;
}

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.
