Comentarios

Una tupla es una estructura de datos que tiene un número específico y una secuencia de valores. La Tuple<T1,T2,T3,T4,T5> clase representa una tupla de 5 o un quintuple, que es una tupla que tiene cinco componentes.

Puede crear instancias de un Tuple<T1,T2,T3,T4,T5> objeto llamando al constructor o al Tuple<T1,T2,T3,T4,T5> método estático Tuple.Create<T1,T2,T3,T4,T5>(T1, T2, T3, T4, T5) . Puede recuperar el valor de los componentes de la tupla mediante las propiedades de instancia de solo Item1lectura , Item2, Item3, Item4, y Item5 .

Las tuplas se usan normalmente de cuatro maneras diferentes:

• Para representar un único conjunto de datos. Por ejemplo, una tupla puede representar un registro de base de datos y sus componentes pueden representar campos individuales del registro.

• Para facilitar el acceso y la manipulación de un conjunto de datos. En el ejemplo siguiente se define una matriz de Tuple<T1,T2,T3,T4,T5> objetos que contienen los nombres de recorriendo en el fútbol americano, el número de partidos en los que jugaron, y el número de cargas, el total de yardas ganadas y los touchdowns anotados durante esos partidos. La matriz se pasa al ComputeStatistics método , que calcula el número de cargas por juego, yardas medias por juego, promedio de yardas por transporte, promedio de yardas por transporte y número medio de touchdowns por intento.

• Para devolver varios valores de un método sin el uso de out parámetros (en C#) o ByRef parámetros (en Visual Basic). Por ejemplo, el ejemplo anterior devuelve sus estadísticas calculadas, junto con el nombre del reproductor, en una matriz de Tuple<T1,T2,T3,T4,T5> objetos .

• Para pasar varios valores a un método a través de un único parámetro. Por ejemplo, el Thread.Start(Object) método tiene un único parámetro que permite proporcionar un valor al método que ejecuta el subproceso en el inicio. Si proporciona un Tuple<T1,T2,T3,T4,T5> objeto como argumento de método, puede proporcionar la rutina de inicio del subproceso con cinco elementos de datos.
