Type Parameters

T1
The type of the first component of the tuple.

T2
The type of the second component of the tuple.

T3
The type of the third component of the tuple.

T4
The type of the fourth component of the tuple.

T5
The type of the fifth component of the tuple.

T6
The type of the sixth component of the tuple.

T7
The type of the seventh component of the tuple.

T8
The type of the eighth component of the tuple.

Parameters

item1
Type: T1
The value of the first component of the tuple.

item2
Type: T2
The value of the second component of the tuple.

item3
Type: T3
The value of the third component of the tuple.

item4
Type: T4
The value of the fourth component of the tuple.

item5
Type: T5
The value of the fifth component of the tuple.

item6
Type: T6
The value of the sixth component of the tuple.

item7
Type: T7
The value of the seventh component of the tuple.

item8
Type: T8
The value of the eighth component of the tuple.

Return Value

Type: System.Tuple<T1, T2, T3, T4, T5, T6, T7, Tuple<T8>>
An 8-tuple (octuple) whose value is (item1, item2, item3, item4, item5, item6, item7, item8).

Remarks

Create is a helper method that you can call to instantiate an 8-tuple without having to explicitly specify the types of its components.

Note:
You must call the Tuple.Create<T1, T2, T3, T4, T5, T6, T7, T8>(T1, T2, T3, T4, T5, T6, T7, T8) constructor to create a tuple with nine or more components unless your language provides a special syntax for this purpose. The static (Shared in Visual Basic) methods of the Tuple class cannot be used to create a tuple with nine or more components.

Examples

The following example creates an 8-tuple whose components are prime numbers that are less than 20.

Dim primes = Tuple.Create(2, 3, 5, 7, 11, 13, 17, 19)

var primes = Tuple.Create(2, 3, 5, 7, 11, 13, 17, 19);

This is equivalent to the following example, which uses the Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> class constructor instead of the Create factory creation method. Note that instantiating a Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object in this way involves considerably more code, because you must declare a nested Tuple<T1> object as the Tuple<T1, T2, T3, T4, T5, T6, T7, TRest> object's eighth component to produce an octuple.

Dim primes As New Tuple(Of Integer, Integer, Integer, Integer, _ 
                           Integer, Integer, Integer, _
                           Tuple(Of Integer)) _
                       (2, 3, 5, 7, 11, 13, 17, _
                        New Tuple(Of Integer)(19))

var primes = new Tuple<int, int, int, int, int, int, int,
                 Tuple<int>>(2, 3, 5, 7, 11, 13, 17,
                 new Tuple<int>(19));
