Point.Equality Operator (Point, Point)

 

Compares two Point structures for equality.

Namespace:   System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)

public static bool operator ==(
	Point point1,
	Point point2
)

Parameters

point1
Type: System.Windows.Point

The first Point structure to compare.

point2
Type: System.Windows.Point

The second Point structure to compare.

Return Value

Type: System.Boolean

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

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.

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;
