Point3D.Inequality(Point3D, Point3D) Оператор

Определение

Сравнивает две структуры Point3D, чтобы выявить различие.Compares two Point3D structures for inequality.

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

Параметры

point1
Point3D

Первая структура Point3D для сравнения.The first Point3D structure to compare.

point2
Point3D

Вторая структура Point3D для сравнения.The second Point3D structure to compare.

Возвращаемое значение

Boolean

Значение true, если координаты X, Y и Z объектов point1 и point2 различаются; в противном случае значение false.true if the X, Y, and Z coordinates of point1 and point2 are different; otherwise, false.

Примеры

В следующем примере показано, как использовать перегруженный оператор неравенства, чтобы проверить Point3D , не равны ли две структуры.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)

Комментарии

Две Point3D структуры не равны, если значения X свойств, и отличаются Y Z .Two Point3D structures are not equal if the values of their X, Y, and Z properties are different.

Поскольку Double значения могут терять точность при выполнении арифметических операций над ними, сравнение двух Point3D логически эквивалентных экземпляров может завершиться ошибкой.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.
