Point4D.Inequality(Point4D, Point4D) Operador

Definición

Compara la desigualdad de dos estructuras Point4D.

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 op_Inequality : 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, Z y W de point4D1 y point4D2 son diferentes; de lo contrario, es false.

Ejemplos

En el ejemplo siguiente se muestra cómo usar el operador de desigualdad sobrecargada para comprobar si dos Point4D estructuras no son iguales.

// Checks if two Point4Ds are not equal using the overloaded inequality operator.

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

areNotEqual = (point1 != point2);
// areNotEqual is True

// Displaying Results
syntaxString = "areNotEqual = (point1 != point2);";
resultType = "Boolean";
operationString = "Checking if two 3D points are not equal";
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString);
' Checks if two Point4Ds are not equal using the overloaded inequality operator.

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

areNotEqual = (point1 <> point2)
' areNotEqual is True

' Displaying Results
syntaxString = "areNotEqual = (point1 != point2)"
resultType = "Boolean"
operationString = "Checking if two 3D points are not equal"
ShowResults(areNotEqual.ToString(), syntaxString, resultType, operationString)

Comentarios

Dos Point4D estructuras no son iguales si los valores de sus Xpropiedades , Y, Zy W son diferentes.

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.
