Tuple<T1,T2,T3,T4>.Equals(Object) Método
Importante
Algumas informações se referem a produtos de pré-lançamento que podem ser substancialmente modificados antes do lançamento. A Microsoft não oferece garantias, expressas ou implícitas, das informações aqui fornecidas.
Retorna um valor que indica se o objeto Tuple<T1,T2,T3,T4> atual é igual a um 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
- obj
- Object
O objeto a ser comparado com essa instância.
true
caso a instância atual seja igual ao objeto especificado; do contrário, false
.
O exemplo a seguir define uma matriz de Tuple<T1,T2,T3,T4> objetos que fornecem dados sobre temperaturas em três vezes durante um dia específico. O Equals(Object) método é chamado para comparar cada Tuple<T1,T2,T3,T4> objeto com todos os outros Tuple<T1,T2,T3,T4> objetos. A saída ilustra que o Equals(Object) método retorna true
somente quando todos os quatro componentes dos Tuple<T1,T2,T3,T4> objetos têm valores iguais.

O parâmetro obj
deve ser considerado igual à instância atual nas seguintes circunstâncias:
É um Tuple<T1,T2,T3,T4> objeto.
Seus quatro componentes são dos mesmos tipos que a instância atual.
Seus quatro componentes são iguais aos da instância atual. A igualdade é determinada pela comparação de igualdade do objeto padrão para cada componente.
