Uwagi

Spójna kolekcja to struktura danych, która ma określoną liczbę i kolejność wartości.A tuple is a data structure that has a specific number and sequence of values. Tuple<T1,T2,T3,T4,T5>Klasa reprezentuje 5-krotkę lub Quintuple, która jest krotką składającą się z pięciu składników.The Tuple<T1,T2,T3,T4,T5> class represents a 5-tuple, or quintuple, which is a tuple that has five components.

Można utworzyć wystąpienie Tuple<T1,T2,T3,T4,T5> obiektu przez wywołanie Tuple<T1,T2,T3,T4,T5> konstruktora lub metody statycznej Tuple.Create<T1,T2,T3,T4,T5>(T1, T2, T3, T4, T5) .You can instantiate a Tuple<T1,T2,T3,T4,T5> object by calling either the Tuple<T1,T2,T3,T4,T5> constructor or the static Tuple.Create<T1,T2,T3,T4,T5>(T1, T2, T3, T4, T5) method. Możesz pobrać wartość składników krotki przy użyciu właściwości tylko do odczytu,,, Item1 Item2 Item3 Item4 i Item5 wystąpienia.You can retrieve the value of the tuple's components by using the read-only Item1, Item2, Item3, Item4, and Item5 instance properties.

Spójne kolekcje są powszechnie wykorzystywane na cztery różne sposoby:Tuples are commonly used in four different ways:

• Reprezentowanie jednego zestawu danych.To represent a single set of data. Na przykład spójna kolekcja może reprezentować rekord bazy danych, a jej składniki mogą reprezentować poszczególne pola rekordu.For example, a tuple can represent a database record, and its components can represent individual fields of the record.

• Zapewnienie łatwego dostępu do zestawu danych i możliwości wykonywania w nim różnych operacji.To provide easy access to, and manipulation of, a data set. W poniższym przykładzie zdefiniowano tablicę Tuple<T1,T2,T3,T4,T5> obiektów, które zawierają nazwy uruchomionych z powrotem w trybie American piłka, liczbę gier, w których są one odtwarzane oraz liczbę przeniesień, Łączna liczba zdobytych metrów i touchdowns w tych grach.The following example defines an array of Tuple<T1,T2,T3,T4,T5> objects that contain the names of running backs in American football, the number of games in which they played, and the number of carries, total yards gained, and touchdowns scored during those games. Tablica jest przenoszona do ComputeStatistics metody, która oblicza każdą z zapleców liczbę przeniesień na grę, średnią metry na grę, średnią liczbę metrów na przeniesienie i średnią touchdowns na próbkę.The array is passed to the ComputeStatistics method, which calculates each running back's number of carries per game, average yards per game, average yards per carry, and average number of touchdowns per attempt.

• Aby zwrócić wiele wartości z metody bez użycia out parametrów (w języku C#) lub ByRef parametrów (w Visual Basic).To return multiple values from a method without the use of out parameters (in C#) or ByRef parameters (in Visual Basic). Na przykład w poprzednim przykładzie funkcja zwraca dane statystyczne, wraz z nazwą odtwarzacza, w tablicy Tuple<T1,T2,T3,T4,T5> obiektów.For example, the previous example returns its computed statistics, along with the name of the player, in an array of Tuple<T1,T2,T3,T4,T5> objects.

• Przekazywanie wielu wartości do metody za pomocą jednego parametru.To pass multiple values to a method through a single parameter. Na przykład Thread.Start(Object) Metoda ma jeden parametr, który umożliwia podawanie jednej wartości metodzie wykonywanej przez wątek przy uruchamianiu.For example, the Thread.Start(Object) method has a single parameter that lets you supply one value to the method that the thread executes at startup. W przypadku podania Tuple<T1,T2,T3,T4,T5> obiektu jako argumentu metody można dostarczyć procedurę uruchamiania wątku z pięcioma elementami danych.If you supply a Tuple<T1,T2,T3,T4,T5> object as the method argument, you can supply the thread's startup routine with five items of data.
