Tuple<T1,T2,T3,T4,T5,T6>.Equals(Object) Método

Definição

Retorna um valor que indica se o objeto Tuple<T1,T2,T3,T4,T5,T6> 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

Parâmetros

obj
Object

O objeto a ser comparado com essa instância.

Retornos

Boolean

true caso a instância atual seja igual ao objeto especificado; do contrário, false.

Exemplos

O exemplo a seguir define uma matriz de sextuplas que contêm dados populacionais para Los Angeles e Nova York de 1960 a 2000. O primeiro componente de cada sextupla identifica a cidade. O primeiro, terceiro e quarto sextuplas contêm dados para Nova York. A primeira sextupla é uma duplicata da quarta sextupla. O terceiro sextupla identifica a cidade como "Nova York" em vez de "Nova York". Como mostra o exemplo, apenas a quarta sextupla é igual à primeira sextupla.

Comentários

O parâmetro obj deve ser considerado igual à instância atual nas seguintes circunstâncias:

  • É um Tuple<T1,T2,T3,T4,T5,T6> objeto.

  • Seus seis componentes são dos mesmos tipos que a instância atual.

  • Seus seis componentes são iguais aos da instância atual. A igualdade é determinada pela comparação de igualdade do objeto padrão para cada componente.
