Generic clear drop down method

So we have all had to clear out a drop down list but what I would like to do is pass the name of a control to a method that would then clear out the items in the drop down list.

For example...

private void ClearDDLS(string nameOfControl)

{

   [nameOfControl].Items.Clear();

}

How can I make this method generic.  I suppose using Reflection but does anyone have an example?
