Tuple<T1,T2,T3>.Equals(Object) Método

Definición

Devuelve un valor que indica si el objeto Tuple<T1,T2,T3> actual es igual que el objeto especificado.Returns a value that indicates whether the current Tuple<T1,T2,T3> object is equal to a specified object.

public:
 override bool Equals(System::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.The object to compare with this instance.

Devoluciones

true si la instancia actual es igual que el objeto especificado; en caso contrario, false.true if the current instance is equal to the specified object; otherwise, false.

Ejemplos

En el ejemplo siguiente se Tuple<T1,T2,T3>.Equals(Object) llama al método para determinar si alguno de los objetos de una Tuple<T1,T2,T3> matriz de objetos es igual entre sí.The following example calls the Tuple<T1,T2,T3>.Equals(Object) method to determine whether any of the objects in an array of Tuple<T1,T2,T3> objects are equal to one another. La salida refleja el hecho de que Equals(Object) el método true devuelve al comparar Tuple<T1,T2,T3> objetos cuyos componentes tienen los mismos valores.The output reflects the fact that the Equals(Object) method returns true when comparing Tuple<T1,T2,T3> objects whose components have equal values.

Comentarios

El obj parámetro se considera igual a la instancia actual en las siguientes condiciones:The obj parameter is considered to be equal to the current instance under the following conditions:

  • Es un Tuple<T1,T2,T3> objeto.It is a Tuple<T1,T2,T3> object.

  • Sus tres componentes son de los mismos tipos que la instancia actual.Its three components are of the same types as the current instance.

  • Sus tres componentes son iguales a los de la instancia actual.Its three components are equal to those of the current instance. La igualdad viene determinada por el comparador de igualdad de objetos predeterminado para cada componente.Equality is determined by the default object equality comparer for each component.
