Compares two vectors for equality.
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 ( = ) : System.Windows.Vector * System.Windows.Vector -> boolPublic Shared Operator == (vector1 As Vector, vector2 As Vector) As BooleanParameters
- 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.
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;
}
Private Function overloadedEqualityOperatorExample() As Boolean
Dim vector1 As New Vector(20, 30)
Dim vector2 As New Vector(45, 70)
' If the two vectors are equal, areEqual is True,
' otherwise it is False. In this example it is False.
Dim areEqual As Boolean = (vector1 = vector2)
Return areEqual
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.
