Tuple<T1,T2,T3,T4>(T1, T2, T3, T4) 建構函式

定義

命名空間:

System

組件:

System.Runtime.dll

來源:

Tuple.cs

初始化 Tuple<T1,T2,T3,T4> 類別的新執行個體。

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)

參數

item1

T1

Tuple 第 1 個元件的值。

item2

T2

Tuple 第 2 個元件的值。

item3

T3

Tuple 第 3 個元件的值。

item4

T4

元組第四個元件的值。

備註

您也可以使用靜態 Tuple.Create<T1,T2,T3,T4>(T1, T2, T3, T4) 方法來具現化 4 元組物件，而不需要明確指定其元件的類型。 下列範例會 Tuple.Create<T1,T2,T3,T4>(T1, T2, T3, T4) 使用 方法來具現化 4 元組，其元件的類型 String 為 、 Double 、 Double 和 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

這相當於對類別建構函式的 Tuple<T1,T2,T3,T4> 下列呼叫。

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
