Tuple<T1,T2,T3>.Equals(Object) Método
Definición
Importante
Parte de la información hace referencia a la versión preliminar del producto, que puede haberse modificado sustancialmente antes de lanzar la versión definitiva. Microsoft no otorga ninguna garantía, explícita o implícita, con respecto a la información proporcionada aquí.
Devuelve un valor que indica si el objeto Tuple<T1,T2,T3> actual es igual que el objeto especificado.
public:
override bool Equals(System::Object ^ obj);
public override bool Equals (object obj);
public override bool Equals (object? obj);
override this.Equals : obj -> bool
Public Overrides Function Equals (obj As Object) As Boolean
Parámetros
- obj
- Object
Objeto que se va a comparar con esta instancia.
Devoluciones
true
si la instancia actual es igual que el objeto especificado; en caso contrario, false
.
Ejemplos
En el ejemplo siguiente se llama al Tuple<T1,T2,T3>.Equals(Object) método para determinar si alguno de los objetos de una matriz de Tuple<T1,T2,T3> objetos es igual entre sí. La salida refleja el hecho de que el Equals(Object) método devuelve true
al comparar Tuple<T1,T2,T3> objetos cuyos componentes tienen valores iguales.

Comentarios
El obj
parámetro se considera igual a la instancia actual en las condiciones siguientes:
Es un Tuple<T1,T2,T3> objeto .
Sus tres componentes son de los mismos tipos que la instancia actual.
Sus tres componentes son iguales a los de la instancia actual. La igualdad viene determinada por el comparador de igualdad de objetos predeterminado para cada componente.
