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)

Parameters

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

Remarks

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

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

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
