Tuple<T1,T2,T3,T4>(T1, T2, T3, T4) 构造函数

定义

命名空间:

System

程序集:

System.Runtime.dll

程序集:

mscorlib.dll

程序集:

netstandard.dll

初始化 Tuple<T1,T2,T3,T4> 类的新实例。

public:
 Tuple(T1 item1, T2 item2, T3 item3, T4 item4);

public Tuple (T1 item1, T2 item2, T3 item3, T4 item4);

new Tuple<'T1, 'T2, 'T3, 'T4> : 'T1 * 'T2 * 'T3 * 'T4 -> Tuple<'T1, 'T2, 'T3, 'T4>

Public Sub New (item1 As T1, item2 As T2, item3 As T3, item4 As T4)

参数

item1

T1

此元组的第一个组件的值。

item2

T2

此元组的第二个组件的值。

item3

T3

此元组的第三个组件的值。

item4

T4

元组的第四个组件的值。

注解

还可以使用静态 Tuple.Create<T1,T2,T3,T4>(T1, T2, T3, T4) 方法实例化 4 元组对象，而无需显式指定其组件的类型。 下面的示例使用Tuple.Create<T1,T2,T3,T4>(T1, T2, T3, T4)此方法实例化其组件的类型DoubleStringDouble为 4 元组，以及。Double

var tuple4 = Tuple.Create("New York", 32.68, 51.87, 76.3);
Console.WriteLine("{0}: Hi {1}, Lo {2}, Ave {3}",
                  tuple4.Item1, tuple4.Item4, tuple4.Item2,
                  tuple4.Item3);
// Displays New York: Hi 76.3, Lo 32.68, Ave 51.87

let tuple4 =
    Tuple.Create("New York", 32.68, 51.87, 76.3)

printfn $"{tuple4.Item1}: Hi {tuple4.Item4}, Lo {tuple4.Item2}, Ave {tuple4.Item3}"
// Displays New York: Hi 76.3, Lo 32.68, Ave 51.87

Dim tuple4 = Tuple.Create("New York", 32.68, 51.87, 76.3)
Console.WriteLine("{0}: Hi {1}, Lo {2}, Ave {3}",
                  tuple4.Item1, tuple4.Item4, tuple4.Item2,
                  tuple4.Item3)
' Displays New York: Hi 76.3, Lo 32.68, Ave 51.87

这相当于对类构造函数的 Tuple<T1,T2,T3,T4> 以下调用。

var tuple4 = new Tuple<string, double, double, double>
                      ("New York", 32.68, 51.87, 76.3);
Console.WriteLine("{0}: Hi {1}, Lo {2}, Ave {3}",
                  tuple4.Item1, tuple4.Item4, tuple4.Item2,
                  tuple4.Item3);
// Displays New York: Hi 76.3, Lo 32.68, Ave 51.87

let tuple4 =
    Tuple<string, double, double, double>("New York", 32.68, 51.87, 76.3)

printfn $"{tuple4.Item1}: Hi {tuple4.Item4}, Lo {tuple4.Item2}, Ave {tuple4.Item3}"
// Displays New York: Hi 76.3, Lo 32.68, Ave 51.87

Dim tuple4 = New Tuple(Of String, Double, Double, Double) _
                      ("New York", 32.68, 51.87, 76.3)
Console.WriteLine("{0}: Hi {1}, Lo {2}, Ave {3}",
                  tuple4.Item1, tuple4.Item4, tuple4.Item2,
                  tuple4.Item3)
' Displays New York: Hi 76.3, Lo 32.68, Ave 51.87
