Parameters

first IEnumerableT1: The first sequence of elements.
second IEnumerableT2: The second sequence of elements.
third IEnumerableT3: The third sequence of elements.
fourth IEnumerableT4: The fourth sequence of elements.
fifth IEnumerableT5: The fifth sequence of elements.
sixth IEnumerableT6: The sixth sequence of elements.
seventh IEnumerableT7: The seventh sequence of elements.
eighth IEnumerableT8: The eighth sequence of elements.
resultSelector FuncT1, T2, T3, T4, T5, T6, T7, T8, 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.
T3: The type of the elements of third.
T4: The type of the elements of fourth.
T5: The type of the elements of fifth.
T6: The type of the elements of sixth.
T7: The type of the elements of seventh.
T8: The type of the elements of eighth.
TResult: The type of the elements of the result sequence.

Return Value

IEnumerableTResult
A sequence of elements returned by resultSelector.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerableT1. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

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.
