Определение

Возвращает значение, показывающее, равен ли текущий объект Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> указанному объекту.Returns a value that indicates whether the current Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object is equal to a specified object.

 override bool Equals(System::Object ^ obj);
public override bool Equals (object obj);

Public Overrides Function Equals (obj As Object) As Boolean

Параметры

obj
Object Object Object Object

Объект, сравниваемый с данным экземпляром.The object to compare with this instance.

Возвраты

Значение true, если текущий экземпляр равен указанному объекту; в противном случае — false.true if the current instance is equal to the specified object; otherwise, false.

Примеры

В следующем примере определяется пять Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> объектов, содержащих простые числа.The following example defines five Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> objects that contain prime numbers. Затем он сравнивает первый объект с каждым из остальных объектов.It then compares the first object with each of the remaining objects. Как показано в выходных данных, только первый и последний Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> объекты равны, поскольку они имеют одинаковое число компонентов с одинаковыми значениями.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.

Комментарии

obj Параметр рассматривается как равен текущему экземпляру, если он удовлетворяет все перечисленные ниже условия:The obj parameter is considered to be equal to the current instance if it meets all the following conditions:

  • Это Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> объекта.It is a Tuple<T1,T2,T3,T4,T5,T6,T7,TRest> object.

  • Он имеет же общее число компонентов, имеющих те же типы, что и текущий экземпляр.It has the same total number of components that are of the same types as the current instance.

  • Компонентов (включая его вложенные компоненты) считаются равными для текущего экземпляра.Its components (including its nested components) are equal to those of the current instance. Равенство определяется путем сравнения по умолчанию для каждого компонента.Equality is determined by the default equality comparer for each component.
