Tuple<T1,T2,T3,T4,T5,T6,T7,TRest>.Equals(Object) Метод

Определение

Возвращает значение, показывающее, равен ли текущий объект Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> указанному объекту.

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

Параметры

obj
Object

Объект, сравниваемый с данным экземпляром.

Возвращаемое значение

Boolean

Значение true, если текущий экземпляр равен указанному объекту; в противном случае — false.

Примеры

В следующем примере определяются пять Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> объектов, содержащих простые числа. Затем он сравнивает первый объект с каждым из оставшихся объектов. Как показано в выходных данных, только первые и последние Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> объекты равны, так как они имеют одинаковое количество компонентов с одинаковыми значениями.

Комментарии

Параметр obj считается равным текущему экземпляру, если он соответствует всем следующим условиям:

  • Это Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> объект.

  • Он имеет одинаковое общее количество компонентов, которые относятся к тем же типам, что и текущий экземпляр.

  • Его компоненты (включая вложенные компоненты) равны компонентам текущего экземпляра. Равенство определяется функцией сравнения на равенство по умолчанию для каждого компонента.
