Initializes a new instance of the Tuple<T1,T2,T3,T4> class.
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)
- item1
- T1
The value of the tuple's first component.
- item2
- T2
The value of the tuple's second component.
- item3
- T3
The value of the tuple's third component.
- item4
- T4
The value of the tuple's fourth component.
You can also use the static Tuple.Create<T1,T2,T3,T4>(T1, T2, T3, T4) method to instantiate a 4-tuple object without having to explicitly specify the types of its components. The following example uses the Tuple.Create<T1,T2,T3,T4>(T1, T2, T3, T4) method to instantiate a 4-tuple whose components are of type String, Double, Double, and 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
This is equivalent to the following call to the Tuple<T1,T2,T3,T4> class constructor.
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
