Tuple<T1>(T1) 构造函数

定义

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

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

参数

item1
T1

元组的唯一一个分量的值。The value of the tuple's only component.

注解

你还可以使用静态Tuple.Create方法实例化1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 method to instantiate a 1-tuple object without having to explicitly specify the type of its component. 下面的示例使用Create方法实例化1元组, 其组件的类型Int32为。The following example uses the Create method to instantiate a 1-tuple whose component is of type Int32.

var tuple1 = Tuple.Create(12);
Console.WriteLine(tuple1.Item1);     // Displays 12
Dim tuple1 = Tuple.Create(12)
Console.WriteLine(tuple1.Item1)     ' Displays 12

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

var tuple1 = new Tuple<int>(12);
Console.WriteLine(tuple1.Item1);     // Displays 12
Dim tuple1 = New Tuple(Of Integer)(12)
Console.WriteLine(tuple1.Item1)     ' Displays 12
