Tuple<T1, T2, T3, T4> Constructor

Initializes a new instance of the Tuple<T1, T2, T3, T4> class.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

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

Parameters

item1
Type: T1

The value of the tuple's first component.

item2
Type: T2

The value of the tuple's second component.

item3
Type: T3

The value of the tuple's third component.

item4
Type: 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

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
