.NET Framework Class Library
Point..::.Equality Operator

Compares two Point structures for equality.

Namespace:  System.Windows
Assembly:  WindowsBase (in WindowsBase.dll)
Visual Basic
Public Shared Operator = ( _
    point1 As Point, _
    point2 As Point _
) As Boolean
C#
public static bool operator ==(
    Point point1,
    Point point2
)
Visual C++
public:
static bool operator ==(
    Point point1, 
    Point point2
)
F#
static let inline (=)
        point1:Point * 
        point2:Point  : bool

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.

Visual Basic
        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
C#
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;

}
