Point3D.Inequality(Point3D, Point3D) Operatore

Definizione

Spazio dei nomi:

System.Windows.Media.Media3D

Assembly:

PresentationCore.dll

Confronta le due strutture Point3D per stabilirne la disuguaglianza.

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

Parametri

point1

Point3D

Prima struttura Point3D da confrontare.

point2

Point3D

Seconda struttura Point3D da confrontare.

Restituisce

Boolean

true se le coordinate X, Y e Z di point1 e point2 sono diverse, altrimenti false.

Esempio

Nell'esempio seguente viene illustrato come usare l'operatore di disuguaglianza di overload per verificare se due Point3D strutture non sono uguali.

// 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)

Commenti

Due Point3D strutture non sono uguali se i valori delle Xrelative proprietà , Ye Z sono diversi.

Poiché Double i valori possono perdere precisione quando vengono eseguite operazioni aritmetiche su di esse, un confronto tra due Point3D istanze che sono logicamente uguali potrebbe non riuscire.
