タプルとは、特定の数と値のシーケンスを持つデータ構造です。A tuple is a data structure that has a specific number and sequence of values. Tuple<T1,T2,T3,T4,T5>クラスは、5 タプルを表します。 または、5 つのコンポーネントを持つタプルである、5 倍です。The Tuple<T1,T2,T3,T4,T5> class represents a 5-tuple, or quintuple, which is a tuple that has five components.

インスタンス化することができます、Tuple<T1,T2,T3,T4,T5>オブジェクトを呼び出すことによって、Tuple<T1,T2,T3,T4,T5>コンス トラクターまたは静的なTuple.Create<T1,T2,T3,T4,T5>(T1, T2, T3, T4, T5)メソッド。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. タプルのコンポーネントの値を取得するには、読み取り専用を使用してItem1Item2Item3Item4、およびItem5インスタンスのプロパティ。You can retrieve the value of the tuple's components by using the read-only Item1, Item2, Item3, Item4, and Item5 instance properties.

タプルは、4 つの方法でよく使用されます。Tuples are commonly used in four different ways:

  • 単一のデータ セットを表します。To represent a single set of data. たとえば、タプルは、データベースのレコードを表すことができ、そのコンポーネントは、レコードの個々 のフィールドを表すことができます。For example, a tuple can represent a database record, and its components can represent individual fields of the record.

  • 簡単にアクセスして、データ セットの操作を提供します。To provide easy access to, and manipulation of, a data set. 次の例の配列を定義するTuple<T1,T2,T3,T4,T5>タッチダウンの数を再生、ゲームや、実行の数の合計、ヤード アメリカン フットボールでは、実行中の名前を格納するオブジェクトとは、これらのゲームの中にスコア付けします。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. 配列が渡される、ComputeStatisticsメソッドで、各実行中のバックのゲーム、平均のヤード キャリーごとのゲーム、平均のメートル単位あたりの実行の数と試行ごとのタッチダウンの平均数を計算します。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.

  • 使用せず、メソッドから複数の値を返すoutパラメーター (C#) またはByRef(Visual Basic) でのパラメーター。To return multiple values from a method without the use of out parameters (in C#) or ByRef parameters (in Visual Basic). たとえば、前の例の配列で、プレーヤーの名前と共に、計算された統計情報を返しますTuple<T1,T2,T3,T4,T5>オブジェクト。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.

  • 1 つのパラメーターを使用してメソッドには、複数値を渡す。To pass multiple values to a method through a single parameter. たとえば、Thread.Start(Object)メソッドが 1 つのパラメーターの起動時にスレッドを実行する方法の 1 つの値を指定することができます。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. 指定した場合、Tuple<T1,T2,T3,T4,T5>メソッドの引数としてオブジェクトのデータの 5 つの項目を含む、スレッドのスタートアップ ルーチンを指定することができます。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.
