Question

I am looking for a one liner that transforms List<T> into object[]. It’s one liner, so I am not interested in solutions such as foreach, or for…

Any takers?

Hint: No, both List<T>.ToArray() and List<T>.ToArray<object>() don’t work.

Edit: Why List<T>.ToArray<object>() doesn’t work? Because it can’t compile.

Answer 1

mylist.Cast<object>().ToArray() 

That will only iterate once, by the way, in case you were wondering about the performance. O(n). 🙂

Why? Well, because Cast<object> will use deferred execution and won’t actually do anything until the list is iterated by ToArray().
