selecting specific number of cells in array using LINQ

Question

Is it possible to select specific number of of cells in an array based on the index?

for example selecting all cells starting from index 5 to index 15.

I know we can do that using loop or array.copy().

But my question is that possible using LINQ ?

If so, can you paste a demo code ?

and what about effeciency ?

about efficiency both linq approach and copy are efficient and will run at same speed. — M.kazem Akhgary, Mar 12 '16 at 09:34
@M.kazem Akhgary, I'm afraid that using `.Skip(n).Take(m)` is not so efficient as using `Array.Copy`. `Skip/Take` will take O(n + m) time while `Array.Copy` only O(m) time. — Ivan Gritsenko, Mar 12 '16 at 10:25
@IvanGritsenko yes. i didnt notice that. btw for small collections it wouldn't make performance issue. — M.kazem Akhgary, Mar 12 '16 at 10:28

It is possible with the following construction:

arr.Skip(5).Take(10);
