Tuple<T1,T2,T3,T4,T5>.Equals(Object) Método

Definición

Devuelve un valor que indica si el objeto Tuple<T1,T2,T3,T4,T5> 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 define una matriz de objetos de 5 tuplas que contienen datos sobre las temperaturas de los pacientes en dos grupos de pruebas. El primer componente de la matriz proporciona el número del grupo de pruebas y el segundo al quinto componente proporcionan las temperaturas de un paciente a intervalos por hora. Se Tuple<T1,T2,T3,T4,T5>.Equals(Object) llama al método para comparar todos los Tuple<T1,T2,T3,T4,T5> objetos con todos los demás Tuple<T1,T2,T3,T4,T5> objetos. La salida muestra que el Equals método devuelve true solo cuando los cinco componentes de los Tuple<T1,T2,T3,T4,T5> objetos tienen valores iguales.

Comentarios

El obj parámetro se considera igual que la instancia actual en las condiciones siguientes:

  • Es un Tuple<T1,T2,T3,T4,T5> objeto .

  • Sus cinco componentes son de los mismos tipos que la instancia actual.

  • Sus cinco componentes son iguales a los de la instancia actual. La igualdad viene determinada por el comparador de igualdad de objetos predeterminado para cada componente.
