## Definición

Compara dos estructuras Point4D para determinar si son iguales.Compares two Point4D structures for equality.

``````public:
static bool operator ==(System::Windows::Media::Media3D::Point4D point1, System::Windows::Media::Media3D::Point4D point2);``````
``public static bool operator == (System.Windows.Media.Media3D.Point4D point1, System.Windows.Media.Media3D.Point4D point2);``
``static member ( = ) : System.Windows.Media.Media3D.Point4D * System.Windows.Media.Media3D.Point4D -> bool``
``Public Shared Operator == (point1 As Point4D, point2 As Point4D) As Boolean``

#### Parámetros

point1
Point4D

Primera estructura Point4D que se va a comparar.The first Point4D structure to compare.

point2
Point4D

Segunda estructura Point4D que se va a comparar.The second Point4D structure to compare.

#### Devoluciones

Boolean

Es `true` si las coordenadas X, Y y Z de `point4D1` y `point4D2` son iguales; en caso contrario, es `false`.`true` if the X, Y, and Z coordinates of `point4D1` and `point4D2` are equal; otherwise, `false`.

## Ejemplos

En el ejemplo siguiente se muestra cómo usar el operador de igualdad sobrecargado para comprobar si dos estructuras Point4D son iguales.The following example shows how to use the overloaded equality operator to check whether two Point4D structures are equal.

``````// Checks if two Point4D structures are equal using the overloaded equality operator.

Point4D point1 = new Point4D(10, 5, 1, 4);
Point4D point2 = new Point4D(15, 40, 60, 75);
Boolean areEqual;

areEqual = (point1 == point2);
// areEqual is False

// Displaying Results
syntaxString = "areEqual = (point1 == point2);";
resultType = "Boolean";
operationString = "Checking if two 3D points are equal";
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString);
``````
``````' Checks if two Point4D structures are equal using the overloaded equality operator.

Dim point1 As New Point4D(10, 5, 1, 4)
Dim point2 As New Point4D(15, 40, 60, 75)
Dim areEqual As Boolean

areEqual = (point1 = point2)
' areEqual is False

' Displaying Results
syntaxString = "areEqual = (point1 == point2)"
resultType = "Boolean"
operationString = "Checking if two 3D points are equal"
ShowResults(areEqual.ToString(), syntaxString, resultType, operationString)
``````

## Comentarios

Dos estructuras Point4D son iguales si los valores de sus propiedades X, Y, Zy W son iguales.Two Point4D structures are equal if the values of their X, Y, Z, and W properties are the same.

Dado que un valor Double puede perder precisión cuando se realizan operaciones aritméticas en ellos, una comparación entre dos valores Point4D que son lógicamente iguales podría producir un error.Because a Double value can lose precision when arithmetic operations are performed on them, a comparison between two Point4D values that are logically equal might fail.
