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.

Type Parameters

TFirst: The type of items in the first collection.
TSecond: The type of items in the second collection.
