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.
