How to convert IList back to List<T> in a BindingSource?

    BindingSource source = new BindingSource();
    source.Add(new List<string>() { "1", "2", "3" });

     //List<string> theList = source.List;//compile fail.  Can't convert from IList to List<T> implicity
     List<string> theList = source.List as List<string>;//fail, null

I've seen people online creating a method to perform an explicit conversion. This seems like total overkill for this task. Is there a better way to get my list back?

You're adding a List<T> as the first item in the list.

To retrieve it, you would write

(List<string>) source.List[0];

Your code would work if you actually bind to a List<T> by setting the DataSource property.
