Boolean

Es true si las coordenadas X e Y de point1 y de point2 son iguales; en caso contrario, es false.true if both the X and Y coordinates of point1 and point2 are equal; otherwise, false.

Ejemplos

En el ejemplo siguiente se muestra cómo comprobar si dos Point estructuras son iguales utilizando el operador sobrecargado (= =).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

Comentarios

Las coordenadas de un punto se describen mediante Double valores.A point's coordinates are described using Double values. Dado que el valor de Double puede perder precisión cuando se realizan operaciones aritméticas en ellos, es posible que se produzca un error en una comparación entre dos Point valores que son lógicamente iguales.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.
