Freely convert between List and IEnumerable

Question

How can I convert a List to an IEnumerable and then back again?

I want to do this in order to run a series

Answer 1

A List is an IEnumerable, so actually, there's no need to 'convert' a List to an IEnumerable. Since a List is an IEnumerable, you can simply assign a List to a variable of type IEnumerable.

The other way around, not every IEnumerable is a List offcourse, so then you'll have to call the ToList() member method of the IEnumerable.
