Computes the cartestian product of two collections: all possible pairs of items, with the first item taken from the first collection and the second item taken from the second collection. If the first collection has N items, and the second collection has M items, the cartesian product will have N * M pairs.

Namespace: Wintellect.PowerCollections
Assembly:  PowerCollections (in PowerCollections.dll)

Syntax

C#
public static IEnumerable<Pair<TFirst, TSecond>> CartesianProduct<TFirst, TSecond>(
	IEnumerable<TFirst> first,
	IEnumerable<TSecond> second
)
Visual Basic (Declaration)
Public Shared Function CartesianProduct(Of TFirst, TSecond) ( _
	first As IEnumerable(Of TFirst), _
	second As IEnumerable(Of TSecond) _
) As IEnumerable(Of Pair(Of TFirst, TSecond))
Visual C++
public:
generic<typename TFirst, typename TSecond>
static IEnumerable<Pair<TFirst, TSecond>>^ CartesianProduct (
	IEnumerable<TFirst>^ first, 
	IEnumerable<TSecond>^ second
)

Parameters

first
IEnumerable<(Of <TFirst>)>
The first collection.
second
IEnumerable<(Of <TSecond>)>
The second collection.

Return Value

An IEnumerable<Pair<TFirst, TSecond>> that enumerates the cartesian product of the two collections.
