C#
IEnumerable<TResult> GroupJoin<T2, TResult>(
	IIndexScanner<T2> source,
	Func<T, IEnumerable<T2>, TResult> resultSelector
)
Visual Basic
Function GroupJoin(Of T2, TResult) ( _
	source As IIndexScanner(Of T2), _
	resultSelector As Func(Of T, IEnumerable(Of T2), TResult) _
) As IEnumerable(Of TResult)

Parameters

source
Type: C1.LiveLinq.Indexing.Search..::..IIndexScanner<(Of <(<'T2>)>)>
The second indexed collection to join to this collection.
resultSelector
Type: System..::..Func<(Of <(<'T, IEnumerable<(Of <(<'T2>)>)>, TResult>)>)>
A function to create a result element from an element from this collection and a collection of matching elements from the second collection.

Type Parameters

T2
The type of the elements of the second collection.
TResult
The type of the result elements.
