Point3D.Inequality(Point3D, Point3D) Operador

Definição

Compara duas estruturas Point3D quanto à desigualdade.

public:
 static bool operator !=(System::Windows::Media::Media3D::Point3D point1, System::Windows::Media::Media3D::Point3D point2);
public static bool operator != (System.Windows.Media.Media3D.Point3D point1, System.Windows.Media.Media3D.Point3D point2);
static member op_Inequality : System.Windows.Media.Media3D.Point3D * System.Windows.Media.Media3D.Point3D -> bool
Public Shared Operator != (point1 As Point3D, point2 As Point3D) As Boolean

Parâmetros

point1
Point3D

A primeira estrutura Point3D a ser comparada.

point2
Point3D

A segunda estrutura Point3D a ser comparada.

Retornos

Boolean

true se as coordenadas X, Y e Z do point1 e do point2 forem diferentes, caso contrário, false.

Exemplos

O exemplo a seguir mostra como usar o operador de desigualdade sobrecarregado para verificar se duas Point3D estruturas não são iguais.

// Checks if two Point3Ds are not equal using the overloaded inequality operator.

Point3D point1 = new Point3D(10, 5, 1);
Point3D point2 = new Point3D(15, 40, 60);
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 Point3Ds are not equal using the overloaded inequality operator.

Dim point1 As New Point3D(10, 5, 1)
Dim point2 As New Point3D(15, 40, 60)
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)

Comentários

Duas Point3D estruturas não serão iguais se os valores de suas YXpropriedades forem Z diferentes.

Como Double os valores podem perder a precisão quando operações aritméticas são executadas nelas, uma comparação entre duas Point3D instâncias logicamente iguais pode falhar.
