組は、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組 (5 つ) を表します。これは5つのコンポーネントを持つタプルです。The Tuple<T1,T2,T3,T4,T5> class represents a 5-tuple, or quintuple, which is a tuple that has five components.

オブジェクトをインスタンス化するには、 Tuple<T1,T2,T3,T4,T5> Tuple<T1,T2,T3,T4,T5> コンストラクターまたは静的メソッドを呼び出し Tuple.Create<T1,T2,T3,T4,T5>(T1, T2, T3, T4, T5) ます。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、、、、およびの各インスタンスプロパティを使用し Item1 Item2 Item3 Item4 Item5 ます。You can retrieve the value of the tuple's components by using the read-only Item1, Item2, Item3, Item4, and Item5 instance properties.

組は、主に次の4つの方法で使用されます。Tuples are commonly used in four different ways:

• データの1つのセットを表す場合は。To represent a single set of data. たとえば、組はデータベース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.

• データセットに簡単にアクセスして操作できるようにするため。To provide easy access to, and manipulation of, a data set. 次の例では、 Tuple<T1,T2,T3,T4,T5> 米国フットボールでの実行中のバックの名前、再生されたゲームの数、およびそれらのゲーム中に発生したキャリーの数、総使用数、touchdowns スコアを含むオブジェクトの配列を定義しています。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. 配列はメソッドに渡されます。このメソッドは、ゲームごとの ComputeStatistics キャリー数、ゲームあたりの平均ヤード、キャリーあたりの平均メートル、および試行あたりの平均 touchdowns 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.

• outパラメーター (C# の場合) または ByRef パラメーター (Visual Basic) を使用せずに、メソッドから複数の値を返す場合は。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、前の例では、オブジェクトの配列で、計算された統計がプレーヤーの名前と共に返され Tuple<T1,T2,T3,T4,T5> ます。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複数の値をメソッドに渡す場合は。To pass multiple values to a method through a single parameter. たとえば、メソッドに Thread.Start(Object) は、起動時にスレッドが実行するメソッドに1つの値を指定できる1つのパラメーターがあります。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. Tuple<T1,T2,T3,T4,T5>メソッドの引数としてオブジェクトを指定する場合は、スレッドのスタートアップルーチンに5つのデータ項目を指定できます。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.
