Définition

Espace de noms:
System.Windows.Media.Media3D
Assembly:
PresentationCore.dll

Compare l'égalité de deux structures Size3D. Deux structures Size3D sont égales si les valeurs de leurs propriétés X, Y et Z sont identiques.

public:
 static bool operator ==(System::Windows::Media::Media3D::Size3D size1, System::Windows::Media::Media3D::Size3D size2);
public static bool operator == (System.Windows.Media.Media3D.Size3D size1, System.Windows.Media.Media3D.Size3D size2);
static member ( = ) : System.Windows.Media.Media3D.Size3D * System.Windows.Media.Media3D.Size3D -> bool
Public Shared Operator == (size1 As Size3D, size2 As Size3D) As Boolean

Paramètres

size1
Size3D

Première structure Size3D à comparer.

size2
Size3D

Deuxième structure Size3D à comparer.

Retours

Boolean

true si les composants X, Y et Z de size1 et size2 sont égaux ; sinon, false.

Exemples

L’exemple suivant montre comment utiliser l’opérateur d’égalité surchargé pour vérifier si deux Size3D structures sont égales.

// Checks if two Size3D structures are equal using the overloaded == operator. 
// Returns a Boolean.

// Declaring Size3D structure without initializing x,y,z values
Size3D size1 = new Size3D();

// Declaring Size3D structure and initializing x,y,z values
Size3D size2 = new Size3D(5, 10, 15);
Boolean areEqual;

// Assigning values to size1
size1.X = 2;
size1.Y = 4;
size1.Z = 6;

// Checking for equality
areEqual = size1 == size2;

// areEqual is False

// Displaying Results
syntaxString = " areEqual = size1 == size2;";
resultType = "Boolean";
operationString = "Checking if two Size3D structures are equal";
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString);

' Checks if two Size3D structures are equal using the overloaded == operator. 
' Returns a Boolean.

' Declaring Size3D structure without initializing x,y,z values
Dim size1 As New Size3D()

' Declaring Size3D structure and initializing x,y,z values
Dim size2 As New Size3D(5, 10, 15)
Dim areEqual As Boolean

' Assigning values to size1
size1.X = 2
size1.Y = 4
size1.Z = 6

' Checking for equality
areEqual = size1 = size2

' areEqual is False

' Displaying Results
syntaxString = " areEqual = size1 == size2"
resultType = "Boolean"
operationString = "Checking if two Size3D structures are equal"
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString)

Remarques

Étant donné que Double les valeurs peuvent perdre de précision lorsque des opérations arithmétiques sont effectuées sur eux, une comparaison entre deux Size3D instances qui sont logiquement égales peut échouer.
