Tuple<T1,T2,T3,T4,T5,T6,T7,TRest>.Equals(Object) Método
Definição
Retorna um valor que indica se o objeto Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> atual é igual a um objeto especificado.Returns a value that indicates whether the current Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object is equal to a specified object.
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.The object to compare with this instance.
Retornos
true caso a instância atual seja igual ao objeto especificado; do contrário, false.true if the current instance is equal to the specified object; otherwise, false.
Exemplos
O exemplo a seguir define cinco Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objetos que contêm números primos.The following example defines five Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objects that contain prime numbers. Em seguida, ele compara o primeiro objeto com cada um dos objetos restantes.It then compares the first object with each of the remaining objects. Como mostra a saída, somente o primeiro e o último Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objetos são iguais, pois eles têm um número idêntico de componentes com valores idênticos.As the output shows, only the first and the last Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objects are equal, because they have an identical number of components with identical values.

Comentários
O obj parâmetro será considerado igual à instância atual se atender a todas as seguintes condições:The obj parameter is considered to be equal to the current instance if it meets all the following conditions:
É um Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objeto.It is a Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object.
Ele tem o mesmo número total de componentes dos mesmos tipos que a instância atual.It has the same total number of components that are of the same types as the current instance.
Seus componentes (incluindo seus componentes aninhados) são iguais aos da instância atual.Its components (including its nested components) are equal to those of the current instance. A igualdade é determinada pelo comparador de igualdade padrão para cada componente.Equality is determined by the default equality comparer for each component.
