Size3D.Equality(Size3D, Size3D) Operador

Definición

Compara dos estructuras Size3D para determinar si son iguales. Dos estructuras Size3D son iguales si los valores de sus propiedades X, Y y Z son iguales.

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

Parámetros

size1
Size3D

Primera estructura Size3D que se va a comparar.

size2
Size3D

Segunda estructura Size3D que se va a comparar.

Devoluciones

Es true si los componentes X, Y y Z de size1 y size2 son iguales; de lo contrario, es false.

Ejemplos

En el ejemplo siguiente se muestra cómo usar el operador de igualdad sobrecargado para comprobar si dos Size3D estructuras son iguales.

// 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)

Comentarios

Dado que Double los valores pueden perder precisión cuando se realizan operaciones aritméticas en ellos, se podría producir un error en una comparación entre dos Size3D instancias que son lógicamente iguales.
