Membandingkan dua Point3D struktur untuk ketidaksamaan.

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

Parameter

point1: Point3D

Struktur pertama Point3D yang dibandingkan.

point2: Point3D

Struktur kedua Point3D untuk dibandingkan.

Mengembalikan

Boolean

trueXjika koordinat , Y, dan Z dari point1 dan point2 berbeda; jika tidak, false.

Contoh

Contoh berikut menunjukkan cara menggunakan operator ketidaksetaraan yang kelebihan beban untuk memeriksa apakah dua Point3D struktur tidak sama.

// 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)

Keterangan

Dua Point3D struktur tidak sama jika nilai Xproperti , , Ydannya Z berbeda.

Karena Double nilai dapat kehilangan presisi ketika operasi aritmatika dilakukan padanya, perbandingan antara dua Point3D instans yang secara logis sama mungkin gagal.
