注解

元组是具有特定数目和值序列的数据结构。 该 Tuple<T1,T2,T3,T4,T5> 类表示一个 5 元组或五元组，它是具有五个组件的元组。

可以通过调用Tuple<T1,T2,T3,T4,T5>构造函数或静态Tuple.Create<T1,T2,T3,T4,T5>(T1, T2, T3, T4, T5)方法来实例Tuple<T1,T2,T3,T4,T5>化对象。 可以使用只读Item1、Item2、Item3和Item4Item5实例属性检索元组组件的值。

元组通常以四种不同的方式使用：

  • 表示单个数据集。 例如，元组可以表示数据库记录，其组件可以表示记录的各个字段。

  • 为了提供对数据集的轻松访问和操作。 下面的示例定义了一组 Tuple<T1,T2,T3,T4,T5> 对象，这些对象包含在美国足球中跑回的名称、他们踢的比赛次数、携带次数、获得的总码数以及在这些比赛中得分的触地数。 该数组传递给 ComputeStatistics 该方法，该方法计算每个运行后每个游戏的携带次数、每个游戏的平均码数、每个携带的平均码数，以及每个尝试的平均触地数。

  • 从方法返回多个值，而不使用 out C#) 中的参数 (或ByRefVisual Basic) 中的参数 (。 例如，上一个示例在对象数组 Tuple<T1,T2,T3,T4,T5> 中返回其计算统计信息以及玩家的名称。

  • 通过单个参数将多个值传递给方法。 例如，该方法 Thread.Start(Object) 有一个参数，可用于向线程在启动时执行的方法提供一个值。 如果将对象作为方法参数提供 Tuple<T1,T2,T3,T4,T5> ，则可以提供线程的启动例程，其中包含五个项目的数据。
