MoreEnumerableCartesianT1, T2, TResult(IEnumerableT1, IEnumerableT2, FuncT1, T2, TResult) Method

public static IEnumerable<TResult> Cartesian<T1, T2, TResult>(
	this IEnumerable<T1> first,
	IEnumerable<T2> second,
	Func<T1, T2, TResult> resultSelector
)

<ExtensionAttribute>
Public Shared Function Cartesian(Of T1, T2, TResult) ( 
	first As IEnumerable(Of T1),
	second As IEnumerable(Of T2),
	resultSelector As Func(Of T1, T2, TResult)
) As IEnumerable(Of TResult)

public:
[ExtensionAttribute]
generic<typename T1, typename T2, typename TResult>
static IEnumerable<TResult>^ Cartesian(
	IEnumerable<T1>^ first, 
	IEnumerable<T2>^ second, 
	Func<T1, T2, TResult>^ resultSelector
)

[<ExtensionAttribute>]
static member Cartesian : 
        first : IEnumerable<'T1> * 
        second : IEnumerable<'T2> * 
        resultSelector : Func<'T1, 'T2, 'TResult> -> IEnumerable<'TResult> 

Parameters

first  IEnumerableT1

The first sequence of elements.

second  IEnumerableT2

The second sequence of elements.

resultSelector  FuncT1, T2, TResult

A projection function that combines elements from all of the sequences.

Type Parameters

T1

The type of the elements of first.

T2

The type of the elements of second.

TResult

The type of the elements of the result sequence.

Return Value

Usage Note

The method returns items in the same order as a nested foreach loop, but all sequences except for first are cached when iterated over. The cache is then re-used for any subsequent iterations.

This method uses deferred execution and stream its results.
