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.

Pass the List<String> as a parameter to the constructor of a new ArrayList<Object> . List<Object> objectList = new ArrayList<Object>(stringList);
Object[] toArray() With this method, Java converts the ArrayList object values into an array of objects of the class, Object. All classes are descendants of the class Object (beginning with uppercase O). The object of the class Object, has the method toString(). System.
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().

List<T>.Select(x => x as object).ToArray(); Should return an object[].
