Restituisce

Boolean

true se le coordinate X, Y e Z di point1 e point2 sono diverse, altrimenti false.true if the X, Y, and Z coordinates of point1 and point2 are different; otherwise, false.

Esempio

Nell'esempio seguente viene illustrato come utilizzare l'operatore di disuguaglianza di overload per verificare se due Point3D strutture non sono uguali.The following example shows how to use the overloaded inequality operator to check whether two Point3D structures are not equal.

// 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 relative X Y proprietà, e Z sono diversi.Two Point3D structures are not equal if the values of their X, Y, and Z properties are different.

Poiché Double i valori possono perdere precisione quando vengono eseguite operazioni aritmetiche su di essi, un confronto tra due Point3D istanze logicamente equivalenti potrebbe non riuscire.Because Double values can lose precision when arithmetic operations are performed on them, a comparison between two Point3D instances that are logically equal might fail.
