Point4D.Equality(Point4D, Point4D) Operador

Definición

Compara dos estructuras Point4D para determinar si son iguales.

public:
 static bool operator ==(System::Windows::Media::Media3D::Point4D point1, System::Windows::Media::Media3D::Point4D point2);
public static bool operator == (System.Windows.Media.Media3D.Point4D point1, System.Windows.Media.Media3D.Point4D point2);
static member ( = ) : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Point4D -> bool
Public Shared Operator == (point1 As Point4D, point2 As Point4D) As Boolean

Parámetros

point1
Point4D

Primera estructura Point4D que se va a comparar.

point2
Point4D

Segunda estructura Point4D que se va a comparar.

Devoluciones

Boolean

Es true si las coordenadas X, Y y Z de point4D1 y point4D2 son iguales; en caso contrario, es false.

Ejemplos

En el ejemplo siguiente se muestra cómo usar el operador de igualdad sobrecargado para comprobar si dos Point4D estructuras son iguales.

// Checks if two Point4D structures are equal using the overloaded equality operator.

Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
Boolean areEqual;

areEqual = (point1 == point2);
// areEqual is False

// Displaying Results
syntaxString = "areEqual = (point1 == point2);";
resultType = "Boolean";
operationString = "Checking if two 3D points are equal";
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString);
' Checks if two Point4D structures are equal using the overloaded equality operator.

Dim point1 As New Point4D(10, 5, 1, 4)
Dim point2 As New Point4D(15, 40, 60, 75)
Dim areEqual As Boolean

areEqual = (point1 = point2)
' areEqual is False

' Displaying Results
syntaxString = "areEqual = (point1 == point2)"
resultType = "Boolean"
operationString = "Checking if two 3D points are equal"
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString)

Comentarios

Dos Point4D estructuras son iguales si los valores de sus Xpropiedades , Y, Z, y W son iguales.

Dado que un Double valor puede perder precisión cuando se realizan operaciones aritméticas en ellos, es posible que se produzca un error en una comparación entre dos Point4D valores que son lógicamente iguales.
