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

Parameters

point1: Point

The first Point structure to compare.

point2: Point

The second Point structure to compare.

Returns

Boolean

true if both the X and Y coordinates of point1 and point2 are equal; otherwise, false.

Examples

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

Remarks

A point's coordinates are described using Double values. 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.
