Tuple<T1,T2>(T1, T2) 构造函数

定义

初始化 Tuple<T1,T2> 类的新实例。Initializes a new instance of the Tuple<T1,T2> class.

public:
 Tuple(T1 item1, T2 item2);
public Tuple (T1 item1, T2 item2);
new Tuple<'T1, 'T2> : 'T1 * 'T2 -> Tuple<'T1, 'T2>
Public Sub New (item1 As T1, item2 As T2)

参数

item1
T1

此元组的第一个组件的值。The value of the tuple's first component.

item2
T2

此元组的第二个组件的值。The value of the tuple's second component.

注解

你还可以使用静态Tuple.Create<T1,T2>(T1, T2)方法来实例化2元组对象, 而无需显式指定其组件的类型。You can also use the static Tuple.Create<T1,T2>(T1, T2) method to instantiate a 2-tuple object without having to explicitly specify the types of its components. 下面的示例使用Tuple.Create<T1,T2>(T1, T2)方法实例化一个2元组, 其组件的类型String为和DoubleThe following example uses the Tuple.Create<T1,T2>(T1, T2) method to instantiate a 2-tuple whose components are of type String and Double.

var tuple2 = Tuple.Create("New York", 32.68);
Console.WriteLine("{0}: {1}", tuple2.Item1, tuple2.Item2);
// Displays New York: 32.68
Dim tuple2 = Tuple.Create("New York", 32.68)
Console.WriteLine("{0}: {1}", tuple2.Item1, tuple2.Item2)
' Displays New York: 32.68

这等效于对Tuple<T1,T2>类构造函数的以下调用。This is equivalent to the following call to the Tuple<T1,T2> class constructor.

var tuple2 = new Tuple<string, double>("New York", 32.68);
Console.WriteLine("{0}: {1}", tuple2.Item1, tuple2.Item2);
// Displays New York: 32.68
Dim tuple2 = New Tuple(Of String, Double)("New York", 32.68)
Console.WriteLine("{0}: {1}", tuple2.Item1, tuple2.Item2)
' Displays New York: 32.68
